The Perennial Plant Association announced the 2022 Perennial Plant of the Year as Schizachyrium scoparium and cultivars. “The wider selection of little bluestem and cultivars allows the perennial experts in any region to select and promote the cultivars that do best in their location!” https://perennialplant.org/page/2022PPOY

In the July 30, 2021 article “Bayer To Remove Glyphosate From Residential Products” in online Lawn and Landscape information was shared on Bayer’s decision on glyphosate; it says “The company says the decision is geared at managing litigation risk and not because of any safety concerns. Bayer announced yesterday that the company will replace glyphosate in consumer products with alternative active ingredients starting in 2023. There will be no change in the availability of the company’s glyphosate formulations in the U.S. professional and agricultural markets.”

A recent meeting with colleagues on water issues lead to discussion centering around what is the nursery/landscape/garden center industry and its consumers going to do to accommodate climate change? in particular, now that we are seeing the results in area storms, drought, flooding, high temperatures, fires, reduced water availability for communities and increased energy use.  Do we significantly alter product mixes to deal with regional higher temperatures? do we plant more trees, of course, but how do we deal with all those lost in clearing for agriculture production and housing?  Do we become more involved with regulation and zoning laws to save and create green belts? So many factors to consider.  Keep your eye on the website CleanWater3: Reduce, Remediate, Recycle for more on what we should consider in the future.  In the meantime, as they consider all the questions and what we can do to improve our environment and save our species, the site https://www.cleanwater3.org is a great resource on water, it’s use, quality and conservation. And what about the armadillos moving their habitat north and now digging up yards and serving as roadkill in west Kentucky? A good indicator of warmer temperature?

Jacob Stedman KNLA President sent out the “Save the Date” announcement for the in-person KNLA Summer Outing, September 2, 2021.  “A lot has happened since then (The virtual Winter Outing) but if one thing has stayed the same it is our excitement about coming together to share our passion for the industry.  That is why I am very happy to announce our return to in-person.  We hope you can join us on Thursday, September 2nd at Riverfarm Nursery, http://www.riverfarm.com/, in Goshen, KY.  It will be a full day of demonstrations, walking tours, and educational sessions led by industry leaders from around the region. 

Part of the day will be spent taking an in depth look at their growing operation including their new Pot-in-Pot growing system that is being installed this summer.  It will provide the opportunity for us to see how the trees we plant are grown and cared for before they find a spot in a garden, landscape, or public space. See you in September!”


For reasons only magicians know the link to a list of Cicada resource publications online didn’t work.

I posted a KY IPM Nursery/Landscape Short video on a Lean programming addition to assessing plants on arrival to our University of Kentucky Horticulture YouTube Channel. https://www.youtube.com/user/UKRECHort

- Caring for arriving plants: inspect the container The Kentucky Nursery-landscape Integrated Pest Management KNL-IPM YouTube Videos are sponsored by Kentucky Integrated Pest Management from a USDA NIFA grant. This video is about adding, checking the containers plants arrive in, to your Lean incoming plant health checklist.  Damaged containers could, as in this case, lead to a reduction in plant health and possibly plant death due to drought injury when a broken container allows water to run out bypassing the plant substrate/roots. Even if caught early enough to salvage the plant; plant health is compromised potentially leading to disease, insect, water or nutrient disorders,

The publication - “Wet Feet” of Ornamentals - describes how low-lying areas may hold surface water after excessive irrigation or heavy rain and persistent puddling or saturated conditions can result in algal growth and plants in such an environment may decline and die.  While we may attribute such plant loss to being planted too deep; observations of the level of the ground and standing water after rains can indicate saturated soils and lack of aeration for root survival.  This publication by Nicole Ward Gauthier, Extension Plant Pathologist Tracey Parriman, Extension Horticulture Agent, Brad Lee, Extension Water Quality Specialist, is very useful when deciding on plant siting and plants to use in such conditions.

Another publication that contains information on plant siting and water management is Home and Environment HENV-205, Residential Rain Gardens: Design, Construction, and Maintenance by Suzette Walling, Tracy Farmer Institute for Sustainability and the Environment; Ashley Osborne, Environmental and Natural Resource Issues; Brad Lee, Plant and Soil Sciences; and Richard Durham, Horticulture.  It is targeted at homeowner installation but is useful as a guide for designers and contractors to educate their clients when installing a rain garden as a part of a landscape. http://www2.ca.uky.edu/agcomm/pubs/HENV/HENV205/HENV205.pdf

AmericanHort and The Horticulture Research Institute (HRI) released a statement about the Box Tree Moth being found in St. Catherine’s, Ontario and shipments were made to the U.S.  The Animal and Plant Health Inspection Service, U.S. Department of Agriculture has shared information on finding of this destructive pest of boxwood and the action being taken to prevent spread at https://www.aphis.usda.gov/aphis/ourfocus/planthealth/plant-pest-and-disease-programs/pests-and-diseases/sa_insects/box-tree-moth Open the dropdowns for more info and images.

  They say the source is “Between August 2020 and April 2021, a nursery in St. Catharines, Ontario, Canada, shipped boxwood that may have been infested with box tree moth to locations in six States—25 retail facilities in Connecticut, Massachusetts, Michigan, New York, Ohio, and South Carolina—and a distribution center in Tennessee. As of May 27, 2021, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) had confirmed the presence of box tree moth in three facilities in Michigan, one in Connecticut, and one in South Carolina.” And “On May 26, 2021, APHIS issued a Federal Order to halt the importation of host plants from Canada, including boxwood (Buxus species), Euonymus (Euonymus species), and holly (Ilex species).

Watching a video Drawn to the Garden I heard Helen Stewart (hestewart.com) say we are “committing suicide by not taking care of the soil.”  I couldn’t agree more, whether commercial landscapes, our home gardens, production fields or container substrates.

Sue Massey, of Massey Nursery Sales & Consultation, LLC, e-mailed to inquire about Brood X Cicadas that will impact some parts of Kentucky.  They have caused severe damage in West Kentucky in the past, in particular on valuable newly planted trees like dogwoods.  I created a list of a few resources that may be helpful in being sure they will be in your area and what to do about them if they are.  Questions: plant or not? Plant in containers that can be grouped and screened? screen recently planted liners? or spray with Imidacloprid? Or no treatment and hope for the best?  No treatment will lead to pruning out damage made by cicada egg laying on pencil sized branches.

I have put a list of resource publications online at https://nursery-crop-extension.ca.uky.edu/CcicadasintheNurseryLandscape

A Select Few Cicada Resources

 1. Periodical Cicadas in Kentucky


 2. Comparison of Exclusion and Imidacloprid for Reduction of Oviposition Damage to Young Trees by Periodical Cicadas (Hemiptera: Cicadidae)



 3. Cicada Mania. General information about “Cicadas, the most amazing insect in the world.”  https://www.cicadamania.com/

 4. Periodical Cicada: Guardians of Time

5. Mapping Brood X Periodical Cicadas in Kentucky

Posted on April 13, 2021


6. Managing cicadas in nurseries and landscapes


Nursery Magazine article on spray drift injury is excellent and Steve Black’s, Raemelton Farm, Frederick County, Maryland attention to detail in such an incident develops a protocol all should follow.  Most important he had records of the growth of the plants he grows.  Something all nursery owners have in their heads in order to determine time to sell but maybe not in a form of record keeping.  Maybe that can be determined and created from inventory records.

Dr. Nicole Gauthier gave a fire blight presentation at a recent fruit conference that was very appropriate to those that grow apples, pears, and crabapples – Fire Blight Management – https://youtu.be/Yad1Yw1xnFw Information is applicable to the time of the presentation.  Please use publications mentioned and current Kentucky Pest News https://plantpathology.ca.uky.edu/extension/kpn for time appropriate guidance.

Keeping track of past-employees and students is always interesting.  Sarah Vanek past UK/KHC Nursery Crops Extension Associate was highlighted in Garden Center Magazine, May 6, 2019, by author Brooke Bilyj, for her efforts to increase Instagram followers for Mulhall’s called  - Insta-green: How to get 20,000 Instagram followers - Mulhall’s tips to create a sizzling social media account that draws in customers.  While two years old the pointers are still of value.


Dr. Amy Fulcher, UTK Associate Professor for Sustainable Ornamental Plant Production and Landscape Management, pointed out two publications relative to the coming periodic cicadas Brood X.  ENT-52 (2003) Periodic Cicadas in Kentucky by Drs. Doug Johnson and Lee Townsend, now retired, is an excellent publication for Kentucky nurserymen,   http://www2.ca.uky.edu/agcomm/pubs/ent/ent52/ent52.pdf and Amanda Taylor’s abstract Preventing Periodic Cicada Damage to Nursery Stock in the Foothills of NC (2017) on the use of Surround, produces a kaolin clay coating that discourages egg laying, https://www.nacaa.com/posters/poster_list.php?poster_id=1603 NBC Today show and John Goddard, UT Loudon County Extension Ag Agent both mentioned the Cicada Safari app as a means of tracking cicada hatching and occurrence.

The ENT-52 map shows Brood X all over Kentucky, but we are not sure how much impact this brood will have on far west Kentucky; some may not have many and other areas may be overwhelmed.

The next biggy outbreak for the Pennyrile will be brood XIX (13 yr.) in 2024. Monitor and subscribe to Kentucky Pest News for more information at https://plantpathology.ca.uky.edu/extension/kpn

Some of the best information you can find on nursery production is the Mark Halcomb Handouts.  https://extension.tennessee.edu/mtnpi/Pages/handouts.aspx  They cover everything about nursery production in a concise fashion.  I have it listed as a “must have” at the number one spot on the list in my Ornamental and Environmental Horticulture Books, https://nursery-crop-extension.ca.uky.edu/content/ornamental-and-environmental-horticulture-books with the comments “great resources that thankfully Amy Fulcher has put online in a readily available site.  Thank you, Mark for writing them and Amy for maintaining availability of these still relevant publications.

The first Center for Crop Diversity (CCD) Cut-Flower program was very informative. UK’s Shari Dutton, staff horticulturalist in the Department of Horticulture recipient of the College of Agriculture, Food and Environment’s Outstanding Staff Award did a wonderful job describing plants to use, or not, as cut-flowers with outstanding visuals. It can be watched at the CCD UKY YouTube channel  https://www.youtube.com/watch?v=F41Z1uM6B84 It included comments by Josh Knight about currently available resources at https://www.uky.edu/ccd/production/crop-resources/nursery-ornamental/cut-flowers he also spoke of an annual survey that is used to create a map of Kentucky cut-flower operations that provides information on cut-flower marketers. The easiest way to know about the survey is to subscribe to the CCD Newsletter or read it at https://www.uky.edu/ccd/newsletter and/or follow them on facebook: https://www.facebook.com/ccduky

Dr. Matthew Chappell, UGA Professor, sent out –– Hello! My name is Zia Williamson, and I am a student at the University of Georgia studying entomology and horticulture. As an Honors project under Dr. Matthew Chappell, I am conducting a survey of Green Industry members regarding desirable skills of horticulture graduates. By conducting this survey, we hope to improve the success of students entering the workforce by understanding what skills horticulture industry employers value most in their employees, particularly those new employees who have recently completed a four year horticulture degree program. The survey consists of 10 short questions and should take less than 5 minutes to complete. Any responses are greatly appreciated and will help in improving the overall quality of students who will soon be entering the workforce.  The links above will take you to the survey or you can use the direct link: https://ugeorgia.ca1.qualtrics.com/jfe/form/SV_2lCZfW99D6ZSpRI

I was blessed to have participated in the Southern Nursery Association Trade Show, Researcher’s Conference, and Plant Conferences since shortly after I started at UK in 1978 when it was huge 10 acre trade show, evenings with top-name entertainment, 100s of faculty and students at the research’s conference. It was the place where I met nursery and landscape industry representatives and many of my colleagues in nursery/landscape research and extension from all over the world. Many of whom only attended this one meeting each year.  2020 was the last SNA Researcher’s Conference and Plant Conference.  As retirement is near at hand, I am saddened that the new young academics will no longer enjoy the benefits of this wonderful supportive organization.  Historically, many SNA presidents were Kentuckians and several University of Kentucky faculty received the Porter Henegar Memorial Award for Horticultural Research most recently Dr. Robert Geneve and in the past Dr. Dewayne Ingram, Dr. Robert McNiel and Dr. Winston Dunwell.  Personally, I consider it one of the greatest honors I have ever received.  I had the good fortune to know every award winner from its establishment in 1969.  I made many great friendships attending SNA.  I am saddened by this announcement.

–––The Southern Nursery Association (SNA) has announced that in a unanimous vote the board of directors has made the decision to cease operation of the 121-yr. old organization. Parts of their announcement is below:

“Founded in 1899, the SNA, a non-profit 501 (c) 6 trade association representing the horticulture industry in the southeastern U.S., accomplished many achievements in fulfilling its mission “to unite and advance the horticulture industry through educational, research and marketing efforts.” The SNA produced one of the industry’s largest trade shows from 1950 – 2009, the SNA Research Conference from 1955 to 2020, and the SNA Plant Conference from 1991 to 2020. In addition, the association hosted a State Officer’s Conference to encourage the exchange of information and learn about various issues affecting the industry throughout the region. Through a collaborative effort with industry researchers, the SNA produced The Best Management Practices (BMP) Guide (http://contents.sna.org/bmpv30.html), designed to help growers identify and promote exceptional management practices, methods and procedures. The first publication was in 1996 (v 1.0) and updated in 2007 (v 2.0) and once again in 2013 (v 3.0). With more than 6,000 copies in use today, this ever-popular guide has been recognized as the undisputed benchmark for horticultural BMPs in the U.S.

The SNA published the Proceedings of the SNA Research Conference and featured more than 3,000 titles comprised of more than 12,500 pages on the SNA website. Hundreds of topics in thirteen categories were presented at the conference and the proceedings have been published online, in an easy-to-use format, as an industry service. This exhaustive library will be transferred to the Horticultural Research Institute (HRI) website (www.hriresearch.org) for future reference.”

I became a Master Gardener and spent three years with Gardening Graces LLC, working in landscaping . I’ve been with Raker-Roberta’s Young Plants (formerly C. Raker & Sons) for 13 years, starting in November of 2007, leading our Trials and Special Projects programs. I am also the Director of Organizational Development and Human Resources.  At Raker-Roberta’s, I’m responsible for all of our outdoor and indoor, open and private trials. Each year we plant over 16 acres of perennials and annuals in containers, hanging baskets, in-ground rows and landscaped beds. I am also responsible for our “boutique” projects. These include everything from providing plants for our local communities and schools to assisting Universities with their research projects and trials.  I have degrees in Computer Maintenance, and Management and Organizational Development, and also a crash course in horticulture due to my current position. My technical background is well suited to setting up and conducting trials and research projects and I feel that I have one of the coolest jobs around. I am passionate about sharing my knowledge with everyone I interact with, speaking at schools, Master Gardener, and Garden Club meetings throughout Michigan.

I am giving up on flowering plants in my home garden due to dense shade and transferring to mosses, ferns, Hydrangea arborescens ‘Annabelle’ and cultivars, native azaleas, buckeyes (red is better in 90% shade than bottlebrush), Lycoris, daffodils and hostas although my creatures like them.  I was intrigued by the recent article in American Horticulture Society magazine Moss Garden Masterpiece by Mark Dwyer.  I walk the woods as often as possible and see many different beautiful mosses native to west Kentucky.  I have always kept George Schenk’s book Moss Gardening: including Lichens, Liverworts and other miniatures, Timber Press, handy.  But I wanted to learn more about Kentucky mosses.  A quick search brought up https://www.inaturalist.org/projects/mosses-liverworts-and-hornworts-bryophytes-of-kentucky?tab=species which I have found useful for identifying the mosses I photograph and some to look for.

I read in Garden Center Magazine “the PPA (Perennial Plant Association) is promoting Calamintha nepeta subsp. nepeta as the 2021 Perennial Plant of the Year.  Like a cloud of confetti, tiny white flowers (sometimes touched with pale blue) appear from early summer to fall on this plant.” A quick search found the web page at  https://perennialplant.org/general/custom.asp?page=2021PPOY

Also, in Garden Center magazine was a profile of Rob Stanfa’s, Murray, Kentucky, Rolling Hills Nursery.  Very Nice! https://www.gardencentermag.com/keyword/rolling-hills-nursery/

Japanese Stiltgrass (Nepalese browntop, Microstegium vimineum) was featured in a recent edition of The Lady Slipper, August 2020, newsletter of the Kentucky Native Plant Society in an article   Invasive Plant Corner – Japanese Stiltgrass.  It has invaded my yard completely from border to border.  I mow the lawn but due to almost 100% shade by a creekside it remains.  In flower beds and rough areas near my deer fence it thrives but is very easy to hand remove from plant beds and surrounding areas. I was shocked to see large expanses of Japanese Stiltgrass in shady areas in bottoms near Kentucky Lake (image) and Lake Barkley in Land Between the Lakes.  https://www.knps.org/2020/08/02/invasive-plant-corner-japanese-stiltgrass-microstegium-vimineum/

“Something to look forward to!” In Allan Armitage’s Here’s Something for the Greenhouse Industry to Look Forward To, Greenhouse Grower, August 4, 2020.

https://www.greenhousegrower.com/crops/ornamentals/heres-something-for-the-greenhouse-industry-to-look-forward-to a bit of cut and paste from the article.

  “We discussed (he and his dental hygienist) how the coronavirus has left us all feeling we were starring in the movie ‘Groundhog Day’ over and over again. Worse, other activities seemed to disappear. Visits with far-off family were postponed, movie dates cancelled, and social interactions erased from the calendar.

  And then Kelly (Robertson, Armitage’s Dental Hygienist) said, ‘I miss those the most. I just took for granted I would always have something to look forward to.’

  To me, it is simple. We are in the business of providing ‘something to look forward to.’ Few other industries can claim this, but it is what we are built on.

  ‘Something to look forward to!’ should be our (green industry) marketing mantra. Those five words should appear in anything we do together as an industry (which is unfortunately very little) or at the very least, they should appear on stationery, catalogs, or marketing notes for individual companies.”  Subscribe to Greenhouse Grower for more of Allan’s witty articles https://www.greenhousegrower.com/subscribe/

The 1st Eastern Region International Plant Propagators’ Society Micro Meeting was the Virtual Tour of Knight Hollow Nursery (tissue culture laboratory) presented by Liz Dunham, July 23, 2020 The recording of the Liz’s tour is at https://www.youtube.com/watch?v=U9EKhho7I3I&t=19s  We will keep you updated on future IPPS-Eastern Region Micro Meetings.

Allan M. Armitage’s Herbaceous Perennial Plants: A Treatise on their Identification, Culture, and Garden Attributes: Fourth Edition is available. (Stipes Publishing, 2020). What an undertaking to create a 4th Edition.  The book is the same format as the past three editions and is still a massive, 7x10 inches, 1090 pages. For reasons unrelated to cost and other reasons even I don’t know, I prefer the softcover.  This edition is available in both hardcover and softcover. As always, I strongly recommend one read Some Thoughts of The Author for Allan’s sometimes humorous opinions.  At this time one can get the book from Allan’s Bookstore http://www.allanarmitage.net/shop

From MANTS 2021 e-mail: “It is with great sadness that we announce that MANTS will not be hosting an in-person tradeshow as planned, January 6-8, 2021, at the Baltimore Convention Center. Instead, we are doubling down and solidifying plans for the launch of an online platform on which exhibitors and registered buyers can connect to network and conduct business.” For more information and the whole announcement see MANTS Updates and FAQ http://dev.mants.com/wp-content/uploads/2020/08/Revised_FAQ_Attendees_Final_8-3-20.pdf

The problem of Laurel Wilt in Sassafras was presented in Kentucky Pest News in July 2019 and the latest July 7, 2020 issue.  Forestry specialists have surveyed west Kentucky and found Laurel Wilt on Sassafras in August 2019 in Christian, Todd and Logan Counties in multiple sites. Lindera benzoin (spicebush) is known to be affected by Laurel Wilt https://www.cabi.org/isc/datasheet/109424#tohostsOrSpeciesAffected  .  For more info see http://forestry.ca.uky.edu/laurel-wilt  to monitor spread see https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fseprd669956.pdf or https://www.fs.usda.gov/main/r8/forest-grasslandhealth The USDA puts out a pest alert and the most recent related to Laurel Wilt is at https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fseprd673152.pdf

Thanks to Dr. Matthew Chappell, UGA Professor, providing us with softwood cuttings of Brown Turkey fig, a plant that has the potential to produce two crops per year, we were able to do a little substrate study for rooting figs under mist.  We placed single-wound cuttings dipped in Hormodin 2 [IBA 3000 ppm (0.3%)] talc in individual quart pots under mist 10 seconds every 10 minutes outdoors with wind protection.  The experiment was to compare substrates pine bark fines/perlite 50/50 volume versus ProMix BX/perlite 50/50 volume.  We will present the results this winter but essentially 36 cuttings rooted; mostly from the wound.  10 of the 40 were very heavily rooted; 4 were poor, 25 were well rooted, ready to be potted and expected to grow well; one tiny piece did not root, it will be dropped from the data due to poor quality.  We needed 16 for the next step to produce fruit from container grown plants; with 32 we can add a factor.  Allie Maternowski, Murray State University sophomore, is leading this project and is already studying production of Celeste fig plants as part of the nursery plant production phase of the study.  Her preliminary results of a study on spicebush was presented when a freshman at the Southern Region American Society of Horticultural Science conference in February 2020. If anyone knows of literature on softwood cutting propagation of fig please drop Allie an e-mail Allie.Maternowski@uky.edu

Reading Nature’s Best Hope by Dr. Doug Tallamy lead to a feeling of hope if we all add plants to our landscapes that host pollinators and insects that serve as food for birds and other critters, create biodiverse landscapes, and in places with care remove invasive plants maybe we can save ourselves from extinction (he didn’t say the I did).  Regrettably, I recently read terrible news of research from Dan Potter’s lab by Adam Baker, UK doctoral student, in a UK Now article - UK Entomologists Find Invasive Paper Wasps Preying on Monarch Butterfly Larvae.  Oh, no! https://uknow.uky.edu/research/uk-entomologists-find-invasive-paper-wasps-preying-monarch-butterfly-larvae?j=242966&sfmc_sub=122684339&l=20203_HTML&u=7507608&mid=10966798&jb=0

States start opening Garden Centers and Nurseries. Several northern markets for Kentucky trees and plants are included.  In the Michigan governor's order which says landscapers, lawn-service companies, plant nurseries can resume operating, subject to social-distancing rules. Big-box retailers no longer have to close off garden centers – (https://wwmt.com ). In the recent Nursery Magazine https://www.nurserymag.com/magazine  e-mail there is a link to the California Guide to COVID-19 and Nurseries.  It may include some tips for Kentucky Garden Centers and Nurseries. It is described as: COVID-19 and Nurseries April 9, 2020 This guidance is based on what is currently known about the transmission and severity of COVID-19 and will be updated as needed.


Dr. Bridget Behe’s weekly podcast Connect 2 Consumer has been very informative.  You can subscribe at http://www.connect-2-consumer.com/121-2/  Last weeks, April 21, 2020, 7 Tips for Gearing Up-Remote or Contactless Sales at the IGC was pertinent to Kentucky Garden Centers still listed as “Non-essential retail businesses, while they cannot allow Kentuckians into stores, can still fill phone and online orders through curbside services or delivery.”

                In the last edition I left off an important newsletter I get notification of by e-mail and read start to finish, the UK College of Agriculture, Department of Horticulture, Center for Crop Diversification (https://www.uky.edu/ccd/) Newsletter that you can subscribe to at https://www.uky.edu/ccd/newsletter


                Cindy Finneseth, Kentucky Horticulture Council Executive Director reported at the KNLA Business meeting about a water/irrigation funding incentive and immediately following sent out an e-mail about The Governor's Office of Agricultural Policy (GOAP)that provides grants, incentives and low-interest loans to help farmers and agribusinesses innovate and grow. The GOAPwas established in 1998 to provide a direct link between the Governor of the Commonwealth and one of Kentucky’s most important industries, agriculture. The Kentucky Agricultural Development Board and the Kentucky Agricultural Finance Corporation Board are administered by the GOAP.

                In her e-mail Cindy said “I’d be happy to work with any nurseries that may be considering irrigation installation/upgrades in navigating GOAP and the application submission process. Cost-share is up to 50% and few applications are submitted each year, so the chance of funding is pretty good. https://agpolicy.ky.gov/funds/Documents/project-guidelines_water.pdf The PIP for small projects (up to $10K) is a very easy process.

                To see all the GOAP/KADF programs go to  https://agpolicy.ky.gov/funds/Pages/program-portal.aspx There is an energy program that may work for operations considering solar or upgrading greenhouses.


The great plants woman Margie Jenkins passed away on January 29, 2020 at 98. A leader in the native plant industry; she was always looking for new or neglected plants for landscapes. Her little nursery in Amite, Louisiana had become a mecca for plants people. She will be missed.  Hammond Research Center (speaking of plant meccas) has the Margie Yates Jenkins Azalea collection at the LSU Ag Center in Hammond.  For more information about Margie read her obituary at  https://www.crainfh.com/obituaries/Margie-Jenkins-2/#!/Obituary


One of the founders of e-gro Dr. W. Garrett Owen, starts at the University of Kentucky Department of Horticulture as an Assistant Extension Professor of Controlled Environment Horticulture.  e-gro puts out alerts that are publications on a problem important to greenhouse and nursery production.  One of the latest was on Lungwort control and mulching the substrate surface for control, http://e-gro.org/pdf/2020_903.pdf .  An excellent publication continuing from Sven Svenson’s original work and publications when he, now at Southeast Missouri State University, was at Oregon State. To subscribe to e-gro go to their website at http://e-gro.org


The January 20, 2020 e-mail from EPA Pesticides Programs: Pesticide Program Update included: EPA Finalizes Glyphosate Mitigation and starts with “EPA has concluded its regulatory review of glyphosate—the most widely used herbicide in the United States. After a thorough review of the best available science, as required under the Federal Insecticide, Fungicide, and Rodenticide Act, EPA has concluded that there are no risks of concern to human health when glyphosate is used according to the label and that it is not a carcinogen.”  https://www.epa.gov/ingredients-used-pesticide-products/glyphosate

One of my responsibilities has been to do a necrology report of those in Kentucky’s nursery/landscape/greenhouse industry that died over the past year at the annual KNLA Business Meeting held during the Winter Outing and Expo.  If you are aware of someone I should mention, please send an e-mail to wdunwell@uky.edu

Those lost in 2019 includes: Cora Leah Martin, 53, of Florence, KY, passed away on December 14, 2019 at Hospice Care of St. Elizabeth in Edgewood, KY surrounded by her loving family. Cora retired from Ammon Nursery after 33 years of service as the general manager and co-owner, Robert Korfhage, son of the late Clinton “Frotz” and Margarett Korfhage, Jules Klein, Jules Klein Nursery son of Yew Dell owners the late Theodore and  Martha Lee Klein, Burt Schwab, Nursery Stock broker who with Peter Scarfe, Scarfe’s Nursery, who also died in 2019 were a frequent exhibitors at KNLA events, D.

HortMemo 2019

December 19, 2019



The University of Kentucky Department of Horticulture will be well represented at SNA/MANTS.  Bob Geneve, Josh Kight, and I along with a student or two with be looking for you to say Happy New Year and to discuss the latest and greatest we learn about from the student and researcher presentations and on the trade show floor. http://www.sna.org and http://www.mants.com/


I noticed GrowerTalks mentioned a Kansas State Entomologist Ray Cloyd publication Aphid Management in Greenhouse Production Systems. It is excellent. A PDF is available at https://www.bookstore.ksre.ksu.edu/pubs/MF3442.pdf A brief on avoiding insecticide resistance appeared in Greenhouse Management a year ago  https://www.greenhousemag.com/article/pest-disease-rotational-program-aphid-insecticide-resistance


Buckeye Yard and Garden Online e-mail 2019 - #42 mentioned a publication Is It Pine, Spruce, or Fir? By Curtis E. Young.  I checked in out and Curtis describes the most obvious of differences.  Some have trouble keeping the genus and the characteristic properly memorized so that it is available when needed. https://ohioline.osu.edu/factsheet/anr-80

How about cypress, arborvitae and Chamaecyparis; what’s a cedar? Etc. Well, that’s a bit more difficult and may require study of online sources, books (Bailey’s Conifers, Cox and Ruter’s Landscaping with Conifers and Ginkos and others), and Conifer Society resources.


I get a bunch of e-mail; most is deleted without opening but there are some I always open or save for later.  In addition to International Plant Propagators’ Society Eastern Region  http://ena.ipps.org/, GrowerTalks newsletters https://www.growertalks.com/newsletters, Nursery Management  https://www.nurserymag.com/  and Horticulture Research Institute (HRI) https://www.hriresearch.org/ I really enjoy the ones I get from Chris Helzer, The Prairie Ecologist https://prairieecologist.com/author/theprairieecologist you can sign up to receive the e-mails or just visit the site occasionally.  His pictures are great and they and the text are always interesting.

In a recent e-mail from News Mt Cuba Center was an article on Sourcing Native Plants -  “We teach ‘right plant, right place,’ but there is much to learn about the suitability for a native plant or cultivar in different landscapes, from a windowbox in the city, to a driveway border in the suburbs, to a large-scale restoration planting in a preserve. Last year, researchers from 12 different institutions gathered at Mt. Cuba Center to try to tackle this issue. Their research is now summarized online at https://www.sourcingnativeplants.com

   This research lays groundwork for future studies about native plants and their ecological value in the landscape. It follows another study (Do leaf-eating insects eat nativars?  https://mtcubacenter.org/do-leaf-eating-insects-eat-nativars/) which found that many cultivars of native plants are just as attractive a food source for leaf-eating insects as their wild counterparts, except in cases where the nativar—that is, native plant cultivar—has been altered to produce darker-colored foliage.

   ‘People should feel empowered to experiment with nativars in their gardens, and to request information about plant provenance at garden centers,’ said Jeff Downing, Mt. Cuba Center’s executive director. We invite you to explore the Sourcing Native Plants website and download the full research report here.” https://onlinelibrary.wiley.com/doi/full/10.1111/rec.12931

The upcoming Eastern Region and Southern Region International Plant Propagators’ Society conferences and tours are coming up.  Both have great educational programs, the tours are always worthy; throw in the great opportunity to meet the elders, and the students and you should attend one or both.  IPPS Eastern Region Conference: Green Capital is in Madison, Wisconsin: October 16-19, 2019. http://ena.ipps.org/   IPPS Southern Region is October 12-16, 2019 in Baton Rouge, LA 70808 http://sna.ipps.org/

Nursery Magazine for September 17, 2019 included an interesting article on a “Biopesticide (that) could curb (the) spotted lanternfly invasion. Scientists are 'cautiously optimistic' after testing showed a nearly 50% decrease of nymphs.” A quick online search lead to Joe Boggs entry in the Buckeye Yard and Garden online back in May https://bygl.osu.edu/index.php/node/1249. To be truthful I found Joe’s article while searching for a definition of the term “coepizootic” that occurs in Joe’s article and in the publication in the Proceedings of the National Academy of Science: https://www.pnas.org/content/116/19/9178

PennState and Cornell scientists have found and identified two soil borne fungi that have killed spotted lanternfly in a PA orchard. In envirobites online article on this the authors wrote:  ‘Coepizootic’ (co-epi-zoo-ot-ic) is just a general term for a disease that is temporarily prevalent and widespread in a population. In this case, the disease is due to two different native fungi pathogens. When we think of fungi, ’insect killer’ may not immediately come to mind– but that is precisely the case with these entomopathogenic fungi.”

The University of Kentucky Research and Education Center Grains and Forages building is nearing completing.  Some things still to do ––some simple like resetting the office name plates to be ADA compliant––others a bit scary I had forgotten we have things for the laboratory and storage cages that still need to be moved back from remote spaces. https://wkrec.ca.uky.edu/file/sept24constructionupdatepdf


The prolonged drought has plants showing serious signs of wilt. Our remontant hydrangeas were overhead-watered very heavily to avoid the wilting.  A bit too much it seemed in spite of no shade this year.  The result was we moved the water table up in the containers and ended up with root systems in the top half of the pot only.  I asked gardeners if they had encountered plants in their purchases in which when pulled from the pot had only half a root system, all had stated that they had bought plants like that. Certainly not a reliable survey but interesting.  Looking for more information on watering hydrangeas I went to Amy Fulcher, Jim Owen and Anthony Lebude’s Hydrangea Production: Species-Specific Production Guide and found a nice discussion on page 4. https://extension.tennessee.edu/publications/Documents/PB1840-B.pdf

The June 2019 edition of the Garden Center Magazine included mention of Dr. Geoffrey Denny’s Fertilize It calculator app for fertilizer injectors. The app is at https://webapps.msucares.com/fertilizeit and the article is in the Garden Centre Magazine Q&A section, the last section requiring you scroll down the online magazine or go straight to it by

I visited with Dr. Edward Chester, Professor and Herbarium Curator Emeritus Austin Peay State University about some problems I was having with identification of some herbaceous natives I had photographed near Hematite Lake in Land between the Lakes.  It turns out unlike trees and shrubs where I know the plant by its leaf, bark, flower, fruit and growth habit I only know wildflowers by their flower.  The pictures I was having difficulty with where showing the fruit of a Viola (Violet, I believe the yellow Viola pubscens) species before the fuzzy white capsule opened showing the seeds and a Scutellaria showing the now obvious “skullcap” following petal drop. Our visit was a wonderful chat about plants, places and friends like the late Tom Barnes who Ed spent a week showing Tom plants he needed to photograph for his book Wildflowers and Ferns of Kentucky and collaborations with UK seed biologists Carol and Jerry Baskin.  I have all of Ed’s print publications most that I purchased very inexpensively at the North Entrance to LBL when I first got here in 1979.  A fire at an LBL storage facility destroyed boxes of copies that were never reprinted. I have found the Ferns and Fern Allies publication Ed co-authored useful. It and other publications as PDF files are available at:  https://www.apsu.edu/field-biology/center/publications.php

Stachys officinalis  ‘Hummelo’ is the 2019 Perennial Plant Association (PPA) Perennial Plant of the Year (PPOY).  A full sun plant that spreads by stolons. It is claimed to be an active pollinator plant and deer resistant; keeping in mind hungry deer will eat whatever is available. A visit to the PPA PPOY website requires one to scroll down to learn the current year’s winner. https://perennialplant.org/page/PPOY.  There is an archive PPOY list of “worthy” perennials to add to any landscape plant list at: https://perennialplant.org/page/PastWinners

I have subscribed to the Places Journal https://placesjournal.org e-mail for a number of years.  Recently, I found their archival “blogs” very interesting.  The one I have taken time to read was The Domestication of the Garage J.B. Jackson’s 1976 essay on the American garage; introduction by Jeffrey Kastner. Archival text by J.B. Jackson https://placesjournal.org/article/j-b-jackson-the-domestication-of-the-garage/?utm_source=mailchimp&utm_medium=email&utm_campaign=Newsletter%2003-01-2019&cn-reloaded=1

There has been a recent discussion about European hornets damaging plants in nurseries.  More so than in past years.  If the numbers at our house back in September each night are an indicator there was a very high population out there.  Anyone seeing damage? Jason Oliver, TN Entomologist wrote an article years ago Journal of Entomological Science (Volume 49 [4]: 352-368).

A more recent article discusses spring trapping queens to reduce populations that may be of interest to those who have experienced damage this fall.  With climate change and the potential for more overwintering of European wasps trapping may become part of an IPM program.



Just reminder in addition to the Kentucky Pest News https://kentuckypestnews.wordpress.com and UK Nursery List Serve https://nursery-crop-extension.ca.uky.edu/listserv Matthew Chappell puts out the interesting Nursery and Landscape Insider https://www.growertalks.com/Newsletters/View/?article=2693


Oh, and how about Nicole Ward Gauthier’s Blog UK - Diseases of Fruit Crops & Ornamentals http://nicolewarduk.blogspot.com


I was reading about Emily Dickinson’s interest in plants in Brainpickings.org and came across “Long before she began writing poems, Dickinson undertook a rather different yet unexpectedly parallel art of contemplation and composition — the gathering, growing, classification, and pressing of flowers, which she saw as manifestations of the Muse not that dissimilar to poems.” She had mounted a significant herbarium collection in a notebook. Her book had been digitized by Harvard Library. I went online and found a copy was $600.00; well beyond my price range.  But, it is available free for the viewing online as Dickinson, Emily, 1830-1886. Herbarium, circa 1839-1846. 1 volume (66 pages) in green cloth case; 37 cm. MS Am 1118.11, Houghton Library of the Harvard Library.  https://iiif.lib.harvard.edu/manifests/view/drs:4184689$1i

August 10, 2018

Richard Lewis Haag, a teacher, mentor, advocate, and celebrated landscape architect, died on May 9, 2018. https://tclf.org/tclf-mourns-loss-rich-haag  I met Rich Haag at a LNA Historic meeting planned by Pat Carey and David and Mary Lou Smallwood.  He was well known as a great plantsman in addition to a creative LA. I had become interested in him before that because he was Rudy Haag’s son, a famous landscape architect and founder of the University of Washington, Department of Landscape Architecture.  I encountered mention of him in every book I read on US landscape architects. Dr. Bob McNiel led the UK Horticulture Club on a tour of his Gas Works considered the first bio-remediated park in the world (DJC,180807) and Bloedel Reserve.  I wrote him to say congratulations for all the mentions in Peter Walker and Melanie Simo’s book, Invisible Gardens: The Search for Modernism in the American Landscape, MIT Press, 1996 which tells brief but wonderful stories of a curious young man who knew, studied with and traveled with the LA greats of which he himself became. He is credited with coining the term “nutrimentals” for useful edible plants in the landscape. Then when Thaïsa Way wrote The Landscape Architecture of Richard Haag; From Modern Space to Urban Ecological Design, University of Washington Press, 2015. I thanked her for writing a book on a Kentucky nurseryman’s son. Rich wrote after I had thanked him at age 90, his studio Richard Haag & Associates was still open then (until 2016), for doing the Cultural Landscape Videos “Dear Winston, Your handwritten note lifted my spirit. I am well and actively practicing (determined to get it right! Especially since clients pay for my lifelong learning). Fill your work with love. Rich Haag, FASLA, BCSLA, Hon AIA." Yes, indeed, the motto for the Kentucky Nursery/Landscape industry “Fill your work with love.”

In addition to Kentucky Pest News Alert the relatively new e-mail newsletter Pest Talks by JC Chong, Clemson, is worthy. Subscribe at: https://www.growertalks.com/Newsletters/Signup/?newsletter=pesttalks

Upcoming meetings of note for the Kentucky Nursery/Landscape industry are the KNLA Summer Outing at City Place in LaGrange, http://knla.org/summer-outing ; the Eastern Region International Plant Propagator’s Society (IPPS) Conference and Tours in Newark, Delaware. http://ena.ipps.org/event/Regional-Events/2018-Eastern-Region-Annual-Conference-Newark-Delaware/VlRFR1l3JTNEJTNE ; Louisville Nursery Association (LNA) meeting. October 17, 2018. Earl Thieneman Greenhouses; and the Southern Region IPPS Conference and Tours in Chattanooga, TN http://sna.ipps.org/event/Regional-Events/2018-Southern-Region-43nd-Annual-Conference-Chattanooga-TN/VURGVU13JTNEJTNE I am trying to attend all if possible; see you there.

A part of the Eastern Region International Plant Propagator’s Society area meeting in Lake County, Ohio was touring nurseries.  Two we visited are using rice hulls on top of the container substrate.  Years ago Dr. Sven Svenson wrote “Surface mulches that dry rapidly will reduce liverwort establishment” http://bryophytes.science.oregonstate.edu/page25.htm . The rice hull mulches were 2 inches deep and were observed to control almost all weeds.  There was considerable savings observed in substituting the rice hulls for substrate. The cost difference is $22.00/cu yd. for rice hulls vs $35.00/cu yd. for substrate.  There was the additional savings in weed control chemicals, application labor, and environmental cost of herbicide, fertilizer and water lost to the ground, air and weeds.  Very interesting!

June 29, 2018

A rough year it turns out. The coldest temperature for us in Princeton, KY was -1.3°F on January 2, 2018 temperatures. While it was -45°F on New Year’s Eve in Embarrass, Minnesota, it was not really cold enough in Princeton, KY to cause extensive injury. Every indication was that the injury was late season often with the evidence of small newly emerging leaves burned off and the distortion mimicking a growth regulator herbicide typical of chilling injury.  We no longer have to worry about the Eucalyptus neglecta level of hardiness 12 plants died even the one that had been evergreen for several years. The Eucalyptus will be removed from further evaluation. The bark splitting on vigorous trees seemed to be related to the subtle differences in environment. We suffered serious damage to ‘Alley Cat’ Pomegranate (even in the over wintering house) and Viburnum luzonicumwith them growing out from the ground.  We had some damage on small Crapemyrtles but little to none on our Japanese Maples.  Now we have the rain leading to a close watch for leaf diseases and difficulty keeping pesticides on for Japanese Beetle. 

As part of the continuing study of bark beetles, in particular the Ambrosia beetle, by Drs Zenaida Viloria, Raul Villanueva, Win Dunwell and Ric Bessin it has been noted ambrosia beetles population was relatively low but damage appeared in most nurseries in spring 2018.  We have learned ambrosia beetle start traveling by flying close to the ground in February.  The traps need to be set early in February.  Sprays need to go on as a preventative trunk application (see Complete Southeastern US Pest Control Guide for chemical recommendations;  https://content.ces.ncsu.edu/southeastern-us-pest-control-guide-for-nursery-crops-and-landscape-plantings/complete-southeastern-us-pest-control-guide ) Continuous trapping indicates there are some beetles around at almost all times with occasional jumps in the population. Research has pointed to stress on trees as a cause of ethylene release that tells the beetles this is a weak tree prepped for attack. Following Best Management Practices (http://contents.sna.org/) and while doing everything in one’s power to maintain healthy trees is a given for maximum growth and return with ambrosia beetles it impacts the cost of pest damage and control.  The damage has included orchard trees leading to traps in orchards being added to those in nurseries.

A recent search for a local arborist lead me to the Find an Arborist page of the International Society of Arborists. It tells which are members of ISA and if they have and what their ISA certification is.  In that ISA is truly international you can find a certified arborist for anywhere in the world.

Ball Publishing just launched another GrowerTalks newsletter which is focused on pest issues called “Pest Talks,” written by Dr. Juang-Horng “JC” Chong, associate professor of Entomology at Clemson University. JC is a member of the Southern Nursery Integrated Pest Management (SNIPM) group and is an author of all SNIPM Publications including the recent The 2017 Southeastern US Pest Control Guide for Nursery Crops and Landscape Plantings https://content.ces.ncsu.edu/southeastern-us-pest-control-guide-for-nursery-crops-and-landscape-plantings This newsletter will focus on grower tips, tricks, news and research related to pest management techniques. You can sign up to receive his newsletter here

The 2018 IPPS Eastern Region Preconference Tour will depart from our host hotel in Newark, Delaware bright and early on Sunday, September 23rd heading southwest into Maryland for stops at four outstanding operations: The Perennial Farm, http://www.perennialfarm.com/ Manor View Farm, http://www.manorview.com, Foxborough Nursery, http://www.foxboroughnursery.com and Emory Knoll Farms, https://www.greenroofplants.com For an overview of the IPPS-ER Tour see http://files.constantcontact.com/e3309f7c001/24c9679a-a7f0-4cbf-bf74-6c8c6e92cbca.pdf

Recently Kentucky Pest News included a graphic that showed the movement of the Emerald Ash Borer (EAB) in Kentucky. https://kentuckypestnews.wordpress.com/2018/03/13/emerald-ash-borers-2018.  Jeff Stringer, Professor and Chair of the Department of Forestry, produced a publication to guide those land owners and tree farmers on management of Ash tree stands in Kentucky. While it may be late for those in north eastern Kentucky those of us in west Kentucky seem to have time to make decisions relative to Ash trees before the population increases to the level to eliminate ash from our forests. See: http://www2.ca.uky.edu/kywoodlandsmagazine/Vol7_No2/Recommendations_for_Ash_pg4-7.pdf

Tennessee Boxwood and Sweetbox quarantine; a report from Senior Nursery Inspector, Joe Collins.
At the request of the production nurseries of Tennessee, the Tennessee Department of Agriculture has implemented a boxwood blight quarantine that will become effective February 4, 2018. This WILL impact any KY nurseries that ship (Buxus spp.) boxwoods and/or (Sarcococca spp.) sweetbox to TN.

There are several steps that KY nurseries will need to take before they can resume shipments to TN. First, they will need to become enrolled in a boxwood blight cleanliness program which will be administered through the State Entomologist’s Office. This program is aimed at prevention of the disease and is based upon 6 key steps: exclusion, water management, sanitation, inspection, training and recordkeeping. More information about the cleanliness program can be found at http://www.uky.edu/Ag/NurseryInspection/pdf/boxwood blight cleanliness program.pdf The next step is that each load of boxwoods going to TN will require a state phytosanitary certificate which is issued by the State Entomologist’s Office. Currently there is no charge for these certificates. Lastly, nurseries that ship boxwoods to TN will be required to notify TN Dept. of Ag three days prior to the estimated shipment of the plants.
This quarantine applies to all boxwood and sweetbox (container, B&B, liners, plugs etc). KY nurseries that ship boxwood and sweetbox to TN should contact Joe Collins (joe.collins@uky.edu or 859.218.3341) for more information. It is important to not wait until the last minute to finalize all the details. The boxwood blight cleanliness program may require a site visit by an inspector prior to enrolling in the program and state phytosanitary certificates may require several days to generate.

Kentucky Nursery & Landscape Association announced the KNLA Spring Training and Trade Show dates are January 24-25, 2018 and the location, Ramada Plaza Louisville Hotel and Conference Center, 9700 Bluegrass Parkway Louisville KY 40299.  Some changes have been made to make it better; all programs will be in rooms separate from the trade show to give more room for the trade show and reduce the noise during educational programs.

Allium 'Millenium' is the 2018 Perennial Plant of the year. Perennial Plant Association (PPA) announcement is at http://www.perennialplant.org/index.php/component/k2/item/198-2018-perennial-plant-of-the-year .Plant Delight’s Nursery described it in their catalog “We are pleased to have introduced this stunning Allium nutans hybrid in 2000, from breeder Mark McDonough (aka Mr. Onion). Allium 'Millenium' represents several generations of breeding (onions) and is head and shoulders above any other allium we grow. The compact 1' tall x 1' wide clump of narrow, glossy green, deer-resistant leaves is topped for over a month in late summer with 2" rosy-purple flower heads, which attract flocks of onion-loving butterflies. We grow Allium 'Millenium' in several locations and have never seen any sign of a stray seedling...garliccimo! For years, we have used the spelling, Millennium, but Mark actually registered it as Millenium, so we've corrected our spelling.”

The Boxwood Blight Best Management Practices online viewable or downloadable publication sponsored by AmericanHort, Horticulture Research Institute and the National Plant Board was revised to Version 2.0 in September 2017. The statement; Updates to the recommendations will be made as more information regarding the disease and its management comes to light may require checking the site occasionally or watching for notices in HortMemo or other publications. https://hortknowledgecenter.org/getattachment/7068c31f-fee0-4541-bf4a-ac89350be97b/BoxwoodBlightBMPs2017.pdf?lang=en-US

The 2017 Southeastern US Pest Control Guide for Nursery Crops and Landscape Plantings https://content.ces.ncsu.edu/southeastern-us-pest-control-guide-for-nursery-crops-and-landscape-plantings was a project of the Southern Nursery IPM Working Group (SNIPM) and collaborators. It is an outstanding publication, long needed, discussed and now reality. Drs. Nicole Ward Gauthier and Matthew T. Springer, University of Kentucky, made significant contributions.  The guide is intended to provide up- to-date information about pest control products (Matthew has a chapter on wildlife management) in nursery crops and ornamental landscape plantings, and as a supplement to the more comprehensive integrated pest management (IPM) manuals for trees and shrubs available for download from the SNIPM web site, https://wiki.bugwood.org/SNIPM . Recommendations for the use of agricultural chemicals are included in this publication as a convenience to the reader. The information is intended as a guide to aid in pest control decision-making and not a substitute for reading and following the directions and guidelines on the pesticide label.

The most recent of the SNIPM publications was announced by the lead editor, Matthew Chappell, UGA Associate Professor – Nursery Production in his Grower Talks Nursery & Landscape Insider:  New IPM Guide: From yours truly comes a brand new integrated pest management resource!
IPM for Shrubs in Southeastern U.S. Nursery Production Volume II is the third book released by the Southern Nursery Integrated Pest Management Working Group (SNIPM) – although the content is applicable across North America. The book covers management practices, abiotic stressors, pathogens, insect pests and weed management strategies in five major ornamental genera including hydrangea, loropetalum, holly, rhododendron (including azalea) and Indian hawthorn. https://wiki.bugwood.org/IPM_Shrub_Book_II  We would appreciate you taking a moment when visiting the publication to take the survey so the next effort will be even more useful to you.

I was working on the next SNIPM Shrub book holly chapter and learned the 2017 Holly of the Year, Ilex glabra , Inkberry or Gallberry an evergreen native to most of the eastern US and southern Canada, and is hardy in Zones 5-10. The leaves are glossy and spineless, but with finely toothed margins. Inkberry forms a rounded, multistemmed shrub, typically 3-10’ (1-3 m) tall and wide, though most commercially available cultivars reach only about 5’ and can be sheared if desired. Given these properties, inkberries are suitable for a wide range of landscape uses, including foundation planting, screening, and informal hedges. They thrive in full sun to part shade, and are tolerant of wet soils. Inkberries are a mostly carefree garden plant, and make a valuable contribution to the natural landscape. They flower in late spring on new growth, and their small white flowers are an important source of nectar for foraging honeybees. Female plants produce pea-sized black fruits, which are not especially conspicuous but are highly attractive to birds in winter.
Many named varieties of Ilex glabra can be found in your local garden center; some of the best cultivars include ‘Shamrock’, ‘Compacta’, ‘Densa’, ‘Nigra’, ‘Chamzin’ (NordicTM), and the recently-introduced ‘Nova Scotia’. Direct quote from Holly of the Year 2017 http://www.hollysocam.org/year.htm archives will be  http://www.hollysocam.org/year_17.htm

Nicole Ward Gauthier sent out the following information for Orchardists but much of it applies to crabapples, hawthorn and serviceberry.

Fire Blight Alert and Risk Map Overview
By: Nicole Ward Gauthier, Extension Specialist 

Apple trees are blooming throughout the commonwealth. Infection by the fire blight bacterium occurs during bloom, thus, protectant antibiotics should be applied when risk is high. 

Risk for infection can be assessed using the Fire Blight Disease Prediction Model. Growers can assess local risk by selecting their county and orchard history. This model incorporates the previous 4 days of weather data plus adds a 7-day forecast for estimating leaf wetness and temperature (thereby estimating risk for bacterial growth and infection). There are 66 Mesonet weather stations throughout Kentucky, thus, weather information for the model is based on data from the closest weather station. For a mobile (phone or tablet) friendly version of this site, visit http://weather.uky.edu/dim.html.

Remember that apple and pear trees must be in bloom for predictions to be accurate. The map overview presented here indicates fire blight risk as of April 10, 2017 (Figure 1).  According to the current assessment, risk is low to marginal across the state due to low humidity during the past several days.  A rain event, however, can increase that risk.  Growers are encouraged to check the model regularly for the most accurate analyses and county-specific forecasts.

Information regarding prevention and management of fire blight can be found in:

From Kentucky Pest News: Two dicamba formulations, XtendiMaxTM (Monsanto) and EngeniaTM (BASF), received federal EPA approval in December for use with RoundupReady2Xtend soybean.  In addition to federal registration, a pesticide must also be registered and approved within a state before it can be sold.  The XtendiMaxTM product received state approval in early January for applications in Kentucky.  The EngeniaTM product is still pending state approval, but it is anticipated in the near future.  These products can be applied before or immediately after planting Roundup Ready 2 Xtend Soybeans or as an in-crop application from emergence (cracking) up to and including the beginning bloom (R1 growth stage of soybeans).  Because of the potential for injury of off-target plants there are rules for application in supplemental labels. In Kentucky, applicators will need to be extra cautious about making an application where sensitive crops such as tobacco, grapes, landscape plants, fruit trees, vegetables, greenhouses or home gardens are growing nearby. https://kentuckypestnews.wordpress.com/2017/01/10/new-dicamba-products-receive-approval-for-use-on-rr2xtend-soybean

March 21, 2016 

I have been invited by the Friends of the UK Arboretum to speak about a topic near and dear to my heart – Kentucky native plants this Thursday, March 24, 2016 at 7 p.m. in UK’s Gluck Auditorium.  The topic title is Kentucky Native Plants: Selection and Care - A discussion of selected Kentucky native plants useful in Kentucky landscapes.  The presentation will include observations, propagation, growing and care of these wonderful plants.


Joe Collins, President National Plant Board, Office of the State Entomologist, Dept. of Entomology, Lexington KY http://nationalplantboard.org and http://www.uky.edu/Ag/NurseryInspection shared with the UK Nursery Crops Group that there is a “new plant certification system designed to help reduce the spread of pests. It is called SANC – Systems Approach to Nursery Certification and it is strictly voluntary. SANC is an audit based system of certification. The first step that a nursery must do is to complete a risk assessment which identifies critical control points (CCP) and uses BMPs to address those situations.  
----there are a lot of parts to it---”. Joe recommends taking a look at the SANC website for a description of what it is all about http://sanc.nationalplantboard.org. This is a Q&A which might help as well: http://sanc.nationalplantboard.org/wp-content/uploads/2013/08/SANC-QA1.pdf

Southern IPM sent out the link to Here’s How to Inspect Your Trees for Emerald Ash Borer March 7, 2016 by Entomology Today included in the article is a video on assessing the possibility of EAB infestation.
for a scientific outlook download the Arboriculture and Urban Forestry 41(2): March 2015 article

Chionanthus virginicus â€“ Fringe Tree has been found infected with Emerald Ash Borer in Ohio.  Below are two trees from the Spring Grove Cemetery where the one on the left is showing symptoms of injury; stunted, thin, yellowing leaves and the hole of the exiting insects in trunks. The one on the right is a cut back following infection showing the extreme vigor of a massive root system supporting new growth. Don Cipollini wrote: “I report here evidence that emerald ash borer can attack and complete development in white fringetree, Chionanthus virginicus L., a species native to the southeastern United States that is also planted ornamentally.” https://jee.oxfordjournals.org/content/108/1/370.full First published January 15, 2015, Darn a beautiful native in jeopardy.  Fringe tree is difficult to propagate and we have been testing different sequences of hot and cold to try to speed up the seed germination process. Considering the potential lack of market for fringe tree now that EAB attack has been confirmed we will stick with Bill Hendricks, Klyn Nursery, method of setting flats of seeds in media (sand, perlite) in the corner of overwintering houses and waiting the 2 – 3 years for the seed to germinate.

Nicole’s information on fire blight applies to ornamental crabapples, pears, Photinia and other Rosaceae family plants is distributed through Dr. John Strang’s Kentucky Fruit Facts electronic mailing list. To subscribe, send an email message In order to get those you have to sign up for Dr. John Strang’s Apple Alert Listserve by e-mailing John at jstrang@uky.edu and he will add you to the list.


Fire Blight Alert and Risk Map Overview By Nicole Ward Gauthier
(To be distributed weekly through orchard bloom)
Apple trees are approaching bloom and many pear are in full bloom, especially in southwestern Kentucky. Infection by the fire blight bacterium occurs during bloom, thus, protectant antibiotics should be applied when risk is high.  
Risk for infection can be assessed using the Fire Blight Disease Prediction Model. Growers can assess local risk by selecting their county and orchard history. This model incorporates the previous 4 days of weather data plus adds a 7-day forecast for estimating leaf wetness and temperature (thereby estimating risk for bacterial growth and infection). There are 66 Mesonet weather stations throughout Kentucky, thus, weather information for the model is based on data from the closest weather station. For a mobile (phone or tablet) friendly version of this site, visit http://weather.uky.edu/dim.html
Remember that apple and pear trees must be in bloom for predictions to be accurate. The map overview below indicates fire blight risk as of March 21, 2016.  According to the current assessment, risk is low due to the cool dry weather.  A rain event, however, can increase that risk.  Growers are encouraged to check the model regularly for the most accurate analyses and county-specific forecasts.
Information regarding prevention and management of fire blight can be found in:
Commercial Fruit Pest Management Guide (ID-232)

Anemone x hybrida 'Honorine Jobert' is the Perennial Plant Association 2016 plant of the year. 'Honorine Jobert' Anemone was found in Jobert Gardens in Verdun, France in 1858. It fits into the “tried and true” category of a perennial plant for Kentucky gardens that blooms in late summer or fall. The picture (yes scanned from a slide) was taken at Bernheim Arboretum years ago.

Most recent bloom at the UKREC is Cornus mas ‘Spring Glow’ and Prunus ‘First Lady’. For images; Cornus mas Spring Glow http://tinyurl.com/j5duuvdand http://tinyurl.com/hwhahb5  First Lady  http://tinyurl.com/hdjzdzb or http://www.usna.usda.gov/Newintro/Prunus_FirstLady_LR.pdf

Redbud bark Dr. Don Hershman sent in an image of redbud bark falling off. Eastern redbud tends to shed bark on older trees revealing an orangish-brown inner bark. Recommendations: There is nothing wrong with the tree as long as the shedding bark simply reveals underlying bark rather than bare wood.


UKREC Horticulture Open House will be Thursday, June 23, 2016, 9:00 am to 12:00 noon at the University of Kentucky Research and Education Center, 1205 Hopkinsville St, Princeton, KY 42445.

Dr. Matthew Chappell, UGA Professor Nursery Crops, put out a call to his colleagues for nursery landscape resources and I cut and pasted from the replies (see below):

Cheryl Wilen, Ph.D. Area IPM Advisor, IPM Advisor Extension Coordinator, Endemic and Invasive Pests and Diseases Strategic Initiative Leader, UC Statewide IPM Program & UCCE, San Diego, CA 92123 replied following comments on Joe Neal's publication mentioned a database that was recently completed.  While not specifically for ornamentals, it does allow for searching. http://herbicidesymptoms.ipm.ucanr.edu/index.cfm?src=ipm1

We commented on going to Joe Neal’s website to find publications on Nursery Landscape Weed control in the last HortMemo but to be more specific Joe Neal’s NCSU Nursery/Landscape Weed Program completed an on-line fact sheet series on herbicide injury symptoms.  
Also available on Joe’s web site are fact sheets on PRE herbicides labeled for nursery and landscape uses. 
and, updated tables of all herbicide ai's labeled for woody and herbaceous ornamental crops, Herbicide efficacy rankings. http://www4.ncsu.edu/~jcneal/
Joe reports they are still working to include more images, and a searchable diagnostic "front page"  for the herbicide injury symptoms series, the fact sheets are completed and may be of interest in the coming season... especially if there are glyphosate resistant crops next door..... 

Whitney Yeary, Amy Fulcher and Brian Lieb wrote Nursery Irrigation: A Guide for Reducing Risk and Improving Production. Amy reports that a strong part of the publication is the success stories.  <http://plantsciences.utk.edu/pdf/fulcher_irrigation_manual.pdf>

Quinn Cypher and Amy Fulcher recently published an online publication series covering alternatives to petroleum-based plastic pots including plantable and biodegradable containers. It is titled Beyond Plastic Pots and the publication numbers are W337A-D in case that helps.  https://extension.tennessee.edu/publications/pages/default.aspx?k=W337&cs=This%20Site&u=https%3A%2F%2Fextension.tennessee.edu%2Fpublications

Dr. Amy Fulcher continues working to get IPMPro updated to version 2 with a new look and additional information and functions.  We will keep you up on the status as it gets closer to completion.

See you at KNLA’s Spring Training & Showplace, January 27-28, 2016. Ramada Plaza Louisville Hotel and Conference Centerhttp://knla.org/event/knlas-spring-training-showplace

The Kentucky Nursery and Landscape Association created a KNLA Wholesale Nursery Location Map of nurseries that participated. It can be found at http://knla.org/wholesale-nursery-location-map or you can pick up a printed copy at the KNLA Spring Training & Showplace.

We have had numerous inquiries about the effect of the warm temperatures followed by the dramatic drop in temperature on landscape, nursery and edible plants. At this time it is very hard to tell. Last year in December we had some forsythia in bloom, a few scattered azalea blooms, and typical winter yellow blooms of Mahonia and bloom on witchhazel pretty much as we do now. We have not observed the bark cracking on small Crapemyrtles and other marginally sensitive plants nor any obvious twig death typical of temperature shifts. There would not seem to be cause for worry. But truth be told, we just don’t know. Last year we were pretty sure the -13°F had to have killed the peach buds but some twigs brought into the warm lab produced flowers and the UK Princeton orchard had one of the best crops ever. The chilling hours at a temperature threshold (Less than or equal to) of 41°F in Paducah are 409, Lexington 384, Covington 493 to December 31, 2015. Chilling hours necessary for bloom of cherries is about 800 but persimmon is 200-400 and given warm temperatures could lose hardiness or bloom any moment. There is some variability in fruit trees in our edible landscapes, e.g. highbush blueberry requires 900-1000 hours while southern highbush only need 150-500 depending on variety; peaches vary greatly from 400-1050. We will just have to wait and see. Chilling while required is not the only factor that impacts when a plant blooms. Growing Degree Hour (heat) requirements also have to be met in order to have bud and flower development.

Mt Cuba Center under the leadership of researcher George Coombs has completed a Research Report on their Coreopsis trials for the mid-Atlantic region. The trials were on clay-based soils and may have some application to Kentucky. The summary is “Mt. Cuba Center 's coreopsis trial evaluated the performance of both annual and perennial tickseed. The best performing perennial species (those marketed as hardy to Zone 6) were C. palustris'Summer Sunshine', C. tripteris 'Flower Tower ', C. tripteris 'Gold Standard', C. verticillata 'Zagreb', C. integrifolia 'Last Dance', C. 'Gilded Lace', and C. verticillata 'Golden Gain'. Among the cultivars sold as annuals, 'Salsa', 'Jive', 'Golden Dream', 'RP #1' (Little Penny), and 'Pineapple Pie' stood above the rest for their superior garden performance. The report (along with others on the right margin) can be found at http://www.mtcubacenter.org/horticultural-research/trial-garden-research/annual-coreopsis-report-2014

Joe Neal has listed numerous weed control and herbicide publications on his home page under the headings Resources and Weed Control Fact sheets. http://www4.ncsu.edu/~jcneal for those interested in nursery/landscape weed control he is developing an herbicide damage image resource that will be available in the future.

While we are talking about Nursery Crops Pest Management a group under the leadership of Joe Neal is putting together a Southern Nursery Crops Pest Management publication that will cover the whole area with annually updated chemical recommendations. In the meantime the Virginia Tech publication by Chuan Hong, Peter Shultz, and Jeffrey Derr covers nursery crop disease, insect and weed pests and can be found as a PDF at https://pubs.ext.vt.edu/456/456-017/Section-5_Nursery_Crops-1.pdf

I have been working on a chapter on Ilex, Hollies, for the second IPM Shrub book that will be out next spring and came across the American Holly Society’s 2015 Holly of the Year. They selected Ilex crenata ‘Helleri’. A quick look in Fred Galle’s 1997 book Hollies and I find that Helleri holly has been around a while. It was a seedling selected in 1934 by J. Heller, manager of Newport Nursery. Galle states that at the time his book was published (1997) “Popular dwarf landscape plant; used as the standard to judge dwarf clones.” ‘Helleri’ is a female plant with small dark green leaves and black berries. As with most I. crenata plants the black fruit does not show well against the green foliage.

From HAS – “Help us choose the next special holly! The Holly of the Year committee invites members of the HSA to nominate their favorite hollies to be Holly of the Year. Send up to five (I know its hard to only nominate only five) to Bill Cannon, send them by e-mail to ilexbc@verizon.net . The hollies with the most nominations will get the nod for the next five years.”

While we all knew Abies nordmanniana, Nordman Fir, was a great plant for Kentucky and considering ours from Theodore Klein planted in 1980 during a drought in dusty dry summer soil and watered the day of planting and not since has performed excellently and had to be tolerant of drought it has been proved.
Pool, et. al., 2013, reported that Nordmann Fir "growth was unaffected by drought" indicating it is a great choice for an attractive evergreen for non-irrigated landscapes in Kentucky.

Amy Fulcher wanted to invite you to attend the "Sustainable Nursery Irrigation: Controlling Growth and Reducing Risk from Changing Irrigation Water Resources and Regulations Workshop" on September 25 in McMinnville, TN.  They have an outstanding group of nationally recognized speakers! Stefan Maupin, Tennessee Farm Bureau Federation; Tom Yeager, University of Florida; Jim Owen, Virginia PolyTechnic and State University Donna Fare, USDA; Jane Stanley, Saunders Brothers Nursery; Brian Leib, UT Ag Engineer and Amy Fulcher, UT Nursery Crops. The workshop will begin at the TSU Research Station (am) and move to Blankenship Farms and Nursery (pm) in McMinnville, TN for the hands-on portion of the program.  The workshop website attachments have more information. http://plantsciences.utk.edu/fulcher_sust_nursery_irrigation_wkshp.htm.


Amy Fulcher also asked me to make you aware of a series of five 3 minute videos on mitigating risk due to pests by using systems-based pest management on the UT Nursery Crops Science YouTube channel at https://www.youtube.com/channel/UCS3SvKF9NeE3_b0bpKkjeuQ .  You all may be familiar with Jennifer Parke and others' work adapting systems-based pest management from the food processing industry for nursery crops to help in the fight against sudden oak death.  The videos include lots of great tips and helpful reminders of easy-to-implement practices that help prevent the spread of insects, mites, weeds and diseases during nursery crop production.  Feel free to share with extension agents, area specialists, and growers who may benefit.  Videos were developed by UT undergraduate, Halee Jones, and former UT postdoctoral scientist, Dr. Diana Cochran and were funded by the Southern Risk Management Education Center.

Lagerstroemia winter injury

The Kentucky Nursery & Landscape Assoc. (KNLA) 15th Annual Summer Outing will be September 3, 2014 at Buffalo Trace, 113 Great Buffalo Trace, Frankfort, KY 40601; (502) 696-5926.

See you there!

It is with regret we announce that Sarah Vanek, Extension Associate for Nursery Crops, and her family are moving to Nebraska. We will miss Sarah’s Lean programs, Listserve posts and service to the nursery industry. We wish her and her family well.

Dr. Dewayne Ingram has written a fine publication - Understanding Soilless Media Test Results and Their Implications on Nursery and Greenhouse Crop Management can be found online at: http://www2.ca.uky.edu/agc/pubs/HO/HO112/HO112.pdf 

I was reading David Byer's Crapemyrtle: A Grower's Thoughts to get some info about cutting propagation of the hardy Lagerstroemia fauriei 'Kiowa' so it can be produced in Kentucky nurseries for Kentucky landscapes. In the process I learned cutting propagation of Kiowa Crapemyrtle is near impossible but other L. fauriei cultivars are easier. I will get some other cultivars to add to our L. fauriei cutting research.
In the process of reading I came across words of wisdom that, while David’s observations, seem to ring true. He says:
"My rules for maximizing winter hardiness of these beautiful plants are:
1- Choose cultivars that experience has shown to be most hardy.
2- Plant them only in full sun.
3- Never fertilize crapemyrtle.
4- Never water crapemyrtle.
5- Never prune crapemyrtle.
I realize these are extreme rules that few would choose to follow completely, but experience proves them to be reliable," 
Note "Crapemurder" and irrigation riser in image with barksplitting. My (Win) observation in 2014 is that crapemyrtles that suffered severe pruning "crapemurder" or were newly planted were those most likely damaged (trunk bark splitting).

While speaking of observations related to Crapemyrtle Ruth Dix now retired from the US National Arboretum and who worked closely with Crapemyrtle breeder and David Beyer's dear friend Dr. Don Egolf told me that once Crapemyrtle are established and gain more than 2-2 ½ inch caliper they are less susceptible to cold injury.

Adam Dale and Steve Frank's 2014 publication The Effects of Urban Warming on Herbivore Abundance and Street Tree Condition states what seems obvious - Raleigh, NC trees in warm sites are in poorer condition than those in cooler sites. The paper discusses the influence of environment on insect pests. A good reference. Raleigh<PLoS ONE 9(7): e102996. doi:10.1371/
journal.pone.0102996> http://www.plosone.org/article/fetchObject.action?uri=info%3Adoi%2F10.1371%2Fjournal.pone.0102996&representation=PDF

I am trying to find Kentucky Wisteria, Wisteria frutescens var. macrostachya, in the wild for seed collection. I thought I had it but in talking with David Creech about the length of the blooms it appears I have the shorter bloom native American Wisteria, Wisteria frutescens the parent for 'Amethyst Falls' which we have and it has, similar to the species, short racemes.

IPM for Shrubs in Southeastern US Nursery Production: Vol I is now available online at http://wiki.bugwood.org/SNIPM just click on the IPM Shrub Book under the title New IPM Book for Southeastern Nursery Growers. A lot of time and effort by my colleagues went into adding this first Shrub book to previous work; the IPMPro App and IPM Tree Book: IPM for Select Deciduous Trees in Southeastern US Nursery Production. I am proud to be associated with the outstanding SNIPM group.

The Perennial Plant Association has selected Panicum virgatum ‘Northwind’ as the Perennial Plant Association’s 2014 Perennial Plant of the Yearâ„¢. We have grown it in the UKREC Botanical Garden successfully and find it good as an individual specimen or in mass.  It was recently moved from the landscape to our nursery research gravel beds remediation areas indicating it would be useful in a rain garden. http://www.perennialplant.org/index.php/component/k2/item/141-2014-perennial-plant-of-the-year

AmericanHort, the horticulture industry’s new trade association, formally began January 1 with the closing on December 31, 2013 of the consolidation of the American Nursery & Landscape Association and OFA – The Association of Horticulture Professionals. http://americanhort.org

You may have heard that the Nematology Laboratory at Princeton which tested for Soybean Cyst Nematode has been closed.  While this is true the Nursery Test is different from that which was done for soybean production and UK will continue to do the test needed for Nursery Certification.

Please note there is a new form for SCN sample analyses which contains information on the process. It can be found at: http://www2.ca.uky.edu/agcollege/plantpathology/ext_files/SCN_Analysis_Form_for_Nursery_Trade.pdf

I read on the Hoffman Nursery Site that “Panicum virgatum ‘Northwind’ is the 2014 Plant of the Year awarded by the Perennial Plant Association.  Roy Diblik of Northwind Perennial Farm introduced Panicum virgatum ‘Northwind’ in the early 1990s. It came from seed he collected in 1982 near railroad tracks off of Highway 25 in South Elgin, Illinois. As the seedlings grew, Roy noticed one unusual plant growing upright, rather than arching, with beautiful blue-green leaves.”  See more at: http://hoffmannursery.com/panicum-northwind-plant-of-the-year/#sthash.WyZM4c18.dpu


I had the good fortune to attend the American Holly Society meeting and be an invited speaker.  I do not normally get nervous but when I went to breakfast and found Jules and Bessie Klein, Earl Cully and Aaron, Elwin and Porsche Orton, Mike Hayman, John Swintoski, Scott Buerlin, Kevin Collard, and bunches more of those I hold in very high regard I rushed back to my room and modified my talk to include as many as possible and after being weak kneed to start I got over it and had a wonderful time talking about hollies and my friends in the room.


Martin Stone, Western Kentucky University Professor and Peggy Mckillip, WKU Horticulture Researcher at the Baker Arboretum were on a Kentucky Garden Club Landscape Course program with me.  There I learned that the Downing Museum burned in July with the paintings on display damaged, one painting burned and a tapestry lost to the fire. Thankfully, Martin, students and volunteers removed the art work in storage in the basement from the building undamaged.  Special art restorers are on site working on the damaged art and the section of the museum damaged is being replaced.  While in Bowling Green I visited Mitchel Leichhardt and found him well and that he had installed some new landscape plantings of boxwood (mini-hedge edging), crapemyrtles and perennials.

Want to win an ipad?   Complete this sensor-based irrigation networks survey! Researchers from around the country are trying to determine how sensor-based irrigation networks can benefit the ornamental plant production industry. We would like your help to better understand current practices.  To do this, we have developed a short survey.  

This survey should take 5-10 minutes to complete.  Your participation is the key to the success of this project.  Access the survey by clicking the link below (or typing the address into your internet browser): https://www.research.net/s/ornamental


***All completed surveys will be entered for a chance to win one (1) Apple ipad!***


The information we gather will help create baseline information, and to determine the potential of the sensor systems to improve specific greenhouse, container nursery, and field nursery practices.  It will also help us measure the impacts of changing practices over time and help define research goals at the local, regional, and national levels, to help growers address current and future needs.


All information you provide will be kept STRICTLY CONFIDENTIAL, and only summary information about the industry and aggregated estimates of economic and environmental impacts will be presented. Your individual responses will not be shared with any state or federal regulatory agency, and will be protected as required by Federal law, as part of the University of Maryland human subjects agreement that you will be asked to agree to before you begin the survey.


Any questions or comments can be directed to John Majsztrik: jcmajsz@umd.edu


A forum entitled Climate Change: Values, National Security, and Free Enterprise has been organized by Dr. Paul Vincelli, Professor and Provost's Distinguished Service Professor. He has gathered an exciting and unique lineup of highly respected individuals to provide thoughtful and enlightening presentation on climate change. The forum is to be held on the evening of April 4th on the campus of the University of Kentucky.  The event will be live-streamed.  Please see the following URL for details:http://www2.ca.uky.edu/environment-files/ccflyervincelli.pdf

The Forum is part of the April 2-4, 2013 Environmental Conference: http://www2.ca.uky.edu/environment/enviro_event_2013


Several great papers where in the December 2012 Journal of Environmental Horticulture. Well they are all great papers but one’s I found particularly interesting were:

Ed Gilman and Michael Orfanedes’ Root Pruning and Planting Depth Impact Root Morphology in Containers (J. Environ. Hort. 30:173-181).  As you can tell from the title root pruning and planting depth do influence root morphology with root pruning resulting in higher quality root systems on live oak and two tropical plants.  The authors state in their abstract “Increasingly, producers and consumers are realizing that roots play a major role in nursery tree quality. To remain competitive, producers need to find economically viable methods of increasing quality standards.” 
Gary Know, Bill Klingeman, Mathews Paret and Amy Fulcher’s Management of Pests, Plants Diseases and Abiotic Disorders of Magnolia Species in the Southeastern United States (J. Environ. Hort. 30:228-234) is an outstanding overview of Magnolia production pest management.  Dr. Gary Knox of UFL at Quincy is a magnolia expert and if in your winter travels to warmer climes you are near Quincy, FL west of Tallahassee you should visit his evaluation plots filled with numerous species and cultivars of magnolia.  If you do not have access to the Journal of Environmental Horticulture you can read the information in the IPM for Select Deciduous Trees in Southeastern US Nursery Production book linked from The Southern Nursery Integrated Pest Management (SNIPM) working group page at http://wiki.bugwood.org/SNIPM

UK Plant Diagnostician Paul Bachi sent me a site to keep track of Phytophthora ramorum as it is found in nurseries.  As the site changes each month because the USA PHYTOPHTHORA RAMORUM NURSERY CHRONOLOGY newsletters are pdfs and the file name contains the date of posting it may be easier to go to the sudden oak death nursery-information site to the get the pdf for that month 

Justin MenkeJustin Menke won a Southern Nursery Sidney B. Meadows Scholarship Award for 2012. Justin is an undergraduate student at the University of Kentucky majoring in Landscape Architecture.

J. Bon Hartline, 94, of Anna, Illinois, died Saturday, May 26, 2012 at his home.  I considered him a friend and corresponded with him via letters and HortMemo over the years. He was born March 22, 1918.  He owned and operated Hartline Fruit Farm and Holly Nursery in Anna.  He discovered and introduced many plants including Chief Paduke American Holly, Council Fire Possumhaw Holly, and numerous other holly cultivars as well as naming ‘Chase Manhattan’ Ginkgo (a great story there: Bon was telling the visiting Ted Dudley, USNA and some other guests something to the effect that the form of the Ginkgo if promoted to the Bonzai Society could lead to Chase Manhattan Bank).  Bon was a beloved horticulturist, fruit grower, nurseryman and plantsman known internationally.  He and Ferry were special people to gardeners in the Evansville, IN area when I first moved to Kentucky in 1978. He was a member of the Holly Society and the Rhododendron Society.  He was a member of a group of the greatest horticulturists that ever lived.  The group included people I was fortunate to know: Bob Simpson, Simpson’s Orchard and Nursery (now Simpson’s Nursery); Theodore Klein, Yew Dell Nursery; and Buddy Hubbuch, Bernheim Arboretum Horticulturist. When I last visited, with Betsy Simpson (Bob’s daughter), Ben Cecil and Dan VanBidder, Bon was 91 and had just sold the last experimental aircraft he had built.  If his back had not given out on him I am sure he would have been working on a plane when he died. A very special man indeed!

His daughter, Mary Ann Hartline wrote me. “Mr. Dunwell- My father died in May. He was 94 years old and his body had just given up.  Thank you for your continued interest.  Mary Ann Hartline. P.s. I plan on keeping the yard going. ”  That “the yard” and all its plants will still be there is great, the original Chase Manhattan Ginkgo is there by the driveway, as is the weirdest Magnolia grandiflora I ever saw along with northern most Cunninghamia I had seen at the time I first saw it in the 1980s and an Ilex decidua hedge to name a few.  Of course the home contains Bon’s leaded glass art hanging in the windows and as windows.

This discussion reminds me of Melvin Moffitt’s statements that the socialization of those in the industry at meetings is very important.  I first met Bon and Ferry at a Rhododendron Society Meeting in Evansville.  I first traveled to their home with a fellow experimental aircraft pilot, McCracken County Extension Agent Doug Wilson.  From those meetings I met them and their friends everywhere including Holly Society Meetings and a Yew Dell event.

Upcoming meetings “worthy” of attending and enjoying industry socialization:

IPMPro mentioned in the last edition of HortMemo has set the standard for Nursery/Landscape/Arborist Apple and Android apps now the same group has introduced IPMLite for Landscape gardeners.  Amy Fulcher at the University of Tennessee is the lead developer of a group of Southeastern Horticulturists (including Win Dunwell), Plant Pathologists, Entomologists, and Weed Scientists at seven land-grant universities who created the Apple and Android apps. 

The mobile app IPMLite adds a new high-tech tool to the gardener’s toolbox. This app will help keep them aware via alerts of pests as they develop over the season at their location, as well as provide them how-to information on insect and disease management, pruning and fertilization schedules, and more.

IPMLite enables users to:

  • Receive text-like alerts for time-sensitive pest issues and plant care - alert date adjusted to location so they are always aware of current pest issues
  • View images, pest lifecycle, and management options for major pests of woody plants
  • Reference how-to information and images of cultural practices
  • Track pests and cultural practices in calendar view or a chronological list 

IPMLite was built for the USDA Plant Hardiness Zones 4 through 8 (with capability for Zone 9a and 9b), which includes 20-plus states from west of the Mississippi River, east and north to Pennsylvania and New Jersey, and south to the Gulf Coast.

IPMPro is $24.99 and IPMLite is $9.99 and are available through Apple (iPhone and iPad) and Android marketplaces.

The ANLA Management Clinic a standard event at the Galt House for as long as I can remember is changing to a combined event with OFA.  In a posting at greenhouse product news http://www.gpnmag.com/ofa-anla-planning-new-event-2013 one reads the following statement “OFA CEO Michael Geary, CAE (sic), responding to questions about this event said, ‘“I can tell you it will not be on a beach somewhere – or in Louisville, KY – but we do want an accessible location.’ ------- ‘We’ll get back to you on the name.’”  So it will not be in Louisville and not named the ANLA Management Clinic.  I guess we will just have to follow the plans in newsletters, postings and industry magazines.  ANLA and OFA have Facebook pages that will have the info.

The next UK Nursery Crops educational opportunity will be the June 14 th IPM Scouting Workshop at Trimble County Extension Office, 43 High Country Lane, Bedford, KY and Kenton Abrams Nursery, 8206 North Highway 421, Milton, KY. Contact Win Dunwell 270.365.7541 x 209 or wdunwell@uky.edu

I found a useful online publication Nursery Crop Selection and Market Niches by Gary Knox and Matthew Chappell. The introduction starts out with - Each year, one of the first questions asked by both seasoned and new nursery producers, managers, and owners is: “What plants should be propagated and/or grown in the upcoming season(s)?” Answering this question requires a complex set of inputs ranging from the type of nursery operation that exists to physical location and market trends. - It can be found at http://edis.ifas.ufl.edu/ep455

An IPM for Herbaceous Perennials Book is online. Stanton Gill wrote “We have a brand new, fresh IPM publication for herbaceous perennial nursery growers with insects, disease, biological and chemical control options, fertility management with emphasis on BMP, water management, weed control, and growth regulators. It was joint publication between Karen Rane (UMD), Joyce Latimer (VPI), Brian Wipker (NCS), Andy Senesac (Cornell) , Andrew Ristvey (UMD) and myself (UMD). It is 349 pages long and found online at our web page of www.IPMNET.umd.edu, found under the publication heading. It was just posted in the last month. Since it so long it is downloaded in three sections.” It can be downloaded as 3 pdf’s at: Part 1, http://www.ipmnet.umd.edu/nursery/docs/Part%201-%20EB359PerennialBook-2012-UofMarylandExtension.pdf ; Part 2 http://www.ipmnet.umd.edu/nursery/docs/Part%202-%20EB359PerennialBook-2012-UofMarylandExtension.pdf ; part 3 http://www.ipmnet.umd.edu/nursery/docs/Part%203-%20EB359PerennialBook-2012-UofMarylandExtension.pdf 

From Sarah Vanek’s Kentucky Nurseries ListServe - The Kentucky Department of Agriculture will again be offering the Kentucky Landscape Plant Availability Guide.  Through the online Plant Availability Guide, customers can search for a specific plant product and be provided with a list of nurseries in Kentucky that sell that product.  These are primarily wholesalers but some are retailers.  The guide can also provide a comprehensive list of all the plants offered by a specific business.  In addition, it provides the contact information for these businesses, so potential customers can contact the businesses directly.  To see how the guide works, visit: http://www.kyagr.com/marketing/plantmktg/plantguide/plant.htm

Wholesalers need to submit their current inventories to KDA.  Information about how to do this is included in the letter from KDA that was sent to past participators.  If you did not receive the letter, you are not currently listed in KDA’s Plant Availability Guide.

If you are interested in participating, please see the attached letter for more information.  New entries will need to be added using a template provided at the following website: http://www.kyagr.com/marketing/plantmktg/ornamental.htm

Entries can be added by sending a catalog instead, but this will significantly delay the process of adding your inventory to the database.

If you have any questions, please contact Adam Watson, Produce Marketing Specialist and PACE Staff Coordinator at KDA; adam.watson@ky.gov or 502.564.4983 ext. 281 or Sarah Vanek, sarah.vanek@uky.edu or 859.257.1273

UK Nursery Crops Educational Programs and Resources 2012 


The Southern Nursery Association Porter Henegar Award is a true honor to those that have won it, but having served as chair of the committee I would point out that only one can be presented with this honor but the forty previous recipients nominate several deserving researchers.  I had the pleasure of presenting the 2012 SNA Porter Henegar Award to Dr. Charlie Hall, the Ellison Chair Professor, Texas A&M.  Charlie is a well-known Agricultural Economist who makes economics understandable for members of the Nursery/Landscape industry.  Subscribe to Charlie’s Blog Making Cents of Green Industry Economics to get an indication of his talent. 

KNLA presented an Appreciation Plaque to Dr. Paul Cappiello, Director Yew Dell Gardens, for all the work he so generously volunteers to assist the nursery industry in Kentucky.  As an example he worked especially hard organizing the International Plant Propagator’s Society meeting in Louisville which brought nursery owners and their employees from all over the world to Louisville.

John and Bob Korfhage, Korfhage Landscape & Designs, were inducted into the KNLA Honorary Hall of Fame; a well-deserved recognition for their many years of devoted service to KNLA and the industry.  Both John and Bob have served as KNLA President.  Serving as KNLA President means several years as a board member, then Vice President, then President, then Past-President.  They both were recognized leaders in the nursery/landscape industry at very young ages which lead to their being elected to the office of KNLA President when Korfhage Landscape & Designs was just getting started.  Congratulations and a heartfelt thank you to both.

Nursery Blog Hits the Ground Running
The Southern Region Nursery Production and Ornamental IPM blog http://blog.caes.uga.edu/sehpis a collection of timely tips and articles by contributors from 19 Land-grant University horticulture faculty and/or Cooperative Extension specialists from eight universities in the Southeastern U.S. Our goal is to work together as a team to bring you the information you need in a timely manner and in an easy to digest format. The blog will cover many topics, all ornamental production related, with the majority having an overarching theme based in integrated pest management. All members of the blog team are part of the Southern Nursery Integrated Pest Management (SNIPM) working group; with members in Georgia, Kentucky, North Carolina, South Carolina, Virginia, Texas and Tennessee; representing Entomology, Horticulture, and Plant Pathology. Detailed information and contact information for this working group, established in 2009, can be accessed at http://wiki.bugwood.org/SNIPM
Why is the Nursery Blog necessary?
Nursery crop production (both field and container) of ornamental trees and shrubs is an important sector of US agriculture, especially in the southeastern United States. Ornamental plants are the second most valuable crop in the United States with a market value of $27 billion in 2008 (National Nursery Survey, 2010). The nursery and greenhouse industry is valued at $588 million in North Carolina and $1 billion in Georgia. Additionally, nursery crops ranked 1st and 5th among crops for NC and GA, respectively. Collectively, nursery and greenhouse production in the Appalachian Region (KY, NC, TN, VA and VW) represent $1.95 billion dollars of sales in 2009. Nurseries in these states employed over 25,000 workers. 
The Goal
In a world of rapidly evolving technology we, cooperative extension personnel, believe that we must reach beyond printed and digital publications in order to decrease the time it takes researchers and extension personnel to distribute vital information to growers. In agriculture (and business in general) information can be the difference between profits and losses. In an agriculture production system, such as ornamental production, that information needs to be delivered as quickly as possible. That is our goal and we hope to serve your needs quickly and thoroughly.


Our sympathies to the families of Ms. Ann Lilliard and David Smallwood who passed away recently.  Special people friends of one and all.

Needing Pesticide CEUs plan to attend the November 4 th training at McCracken County Extension office. See announcement in HortMemo Upcoming Meetings list.


I am still working on the program for the December 1, 2011 IPM for the Green Industry Workshop at the UKREC, 1205 Hopkinsville St., Princeton, KY. We will keep you apprised of the progress via HortMemo, Facebook and Twitter.


Dr. Dewayne Ingram is one of the few working on Life Cycle Assessment of nursery production practices. In the process of searching for more information on the topic I was clicking to follow the ANLA Information Center Twitter page of Kellee&Jonathan http://twitter.com/#!/anlaKC when I learned there that ANLA had an ANLA Knowledge Web site http://www.anla.org/knowledgecenter/collections/index.cfm and Dr. Charlie Hall, an economist who makes economics and related topics understandable, is the leader of a Discussion Forum Charlie’s Angle (amusing word play there) and Episode 5 was Our Environmental Footprint: An Inconvenient Truth or Consumer Opportunity. On the right of the page there is a video containing Charlie’s take on the topic. There is a 15 second advertisement before Charlie starts speaking; hang in there. As always an information search leads to unexpected places and I ended up listening to all five episodes of Charlie’s Angle because Charlie’s way of describing topics with props and analogies and a bit of humor, e.g. What does his relatives making Moonshine have to do with Our Value Proposition Episode 2 http://www.anla.org/knowledgecenter/collections/index.cfm?Collection_ID=92


Carey Grable has posted a You Tube video of Vaden Fenton’s Plasticulture Demonstration Program - University of Kentucky Department of Horticulture. The video shows how plastic layers work and demonstrates a water wheel setting of peppers. Thanks to Joe Williams and Vaden for equipment operation and the Agriculture Development Fund and Kentucky Horticulture Council for funding to make this video.

http://www.youtube.com/user/UKRECHort#p/a/u/0/kw8J-70k324 I recently viewed a presentation of a liner production facility that used plasticulture exactly like that demonstrated for producing woody plant liners.


The Water Education Alliance for Horticulture is working with University of Florida Cooperative Extension, OFA, FNGLA, and the German grower association Zentralverband Gartenbau and several experts at universities and companies on topics to help growers conserve, recirculate, and treat irrigation water.

Sarah Vanek sent out the following to the KY Nursery Listserve “I would like to put together a comprehensive list of Kentucky wholesale nursery businesses, and I need your help in doing so.  The goal in creating this list is to provide a centralized location for buyers, such as landscapers and garden centers, to find more local sources of plant material.  I know there are a number of factors involved when buyers chose where to purchase their inventory, but this list will hopefully serve as a starting point for those who are interested in finding more local sources.


If you are a wholesaler and would like your business to be included on the list, please email me, sarah.vanek@uky.edu with the following information: Business Name, Phone, E-mail, City and County, Website (if you have one), a few sentences of advertisement briefly describing your wholesale products (please limit this portion to 75 words or less); include at least the general types of plants you offer (shade trees, ornamental trees, evergreens, shrubs, perennials, etc.); if you would like to, you may also include features unique to your product (e.g. individually labeled for garden center, grown as pot-in-pot, biodegradable containers, etc.), just be sure to keep it to 75 words or less. The information to be provided in this document is by no means intended to reflect each business’s entire inventory, but will serve only as a starting point for discussions between businesses.  I strongly encourage participants to include a website where buyers can find more information about the products and/or business. I plan to post this list online, distribute it through the Kentucky Nursery Listserv, and share it with buyers looking for local plant sources.  Participants will need to notify me if their information changes."

Bouldin Corporation developed WastAway http://www.wastaway.com. On their web site it says “WastAway has developed an innovative process that takes unsorted household garbage and converts it into a product called Fluff®, ---. Fluff is similar in consistency to wood pulp, and can be processed for use as a growing medium for plants and turf, can be gasified to generate steam, can be converted to synthetic fuels such as ethanol, diesel, and gasoline, or can be compressed and extruded to make products such as construction materials.” I saw this product at Hale and Hines Nursery in McMinnville, TN. They are successfully using Fluff® as a component to their container media. For an image click here

Amy Fulcher’s last day is October 28, 2010. To say she will be missed is an understatement.


Vaden Fenton’s cole crop, cabbage and broccoli, demonstration plot would be of interest to anyone incorporating edibles into their landscape - Fall Cole Crop: Extending Your Season Field Tour. October 11, 2010, 3:30 p.m. CDT. University of Kentucky Research and Education Center, 1205 Hopkinsville St, Princeton, KY. Watch for signs pointing to the field off Highway 91 south north of the center entrance or go to the Center for directions.


In Wharton and Barbour’s Trees and Shrubs of Kentucky Linderabenzoin, Spicebush, the fruit images and description are on page 123 not page 133 as in the index and at bottom of flower and habit pages (108 & 253).


The Explorer’s Garden: Shrubs and Vines by Daniel J. Hinkley. 2009, Timber Press, Portland, Oregon, was one of the four 2010 American Horticulture Society’s (AHS) 2010 Book Award Winners. I wrote a review of the book that can be found by clicking on the link and scrolling down the reviews.


The 2010 Kentucky Turfgrass Conference will be October 18-20, 2010 at the Holiday Inn and Convention Center, Bowling Green, KY. For info see http://www.kentuckyturfgrasscouncil.org or http://www.uky.edu/Ag/ukturf/KTC%20-%202010%20Conference.html


The Kentucky Division of Forestry, University of Kentucky Forestry Extension, and the US Forest Service encourages you to mark your calendars for the Emerald Ash Borer Urban Preparedness Conference to be held in Lexington, KY on December 8 – 9, 2010 at the Embassy Suites.


January 24-25, 2011 many of the leading University Nursery Researchers will be in Louisville for the NC-1186: Water Management and Quality for Ornamental Crop Production and Health, annual meeting. A Nursery Industry Sharing session will be the afternoon session on January 25, 2011. Brief invited presentations by industry representatives will start this sharing opportunity. This meeting is prior to the Kentucky Landscape Industries Winter Conference and the Mid-States Trade Show which will be in conjunction with the ANLA Management Clinic all the week of January 24 th.


Steve Foltz’s Ohio Nursery Short Course presentation Throw Down Panel – Native, Potential Invasives, LEED is on Tuesday, January 25, 2011 at 10:45-11:45 ET. If you have been keeping up with Steve’s article Sustainability of Native and Non-Native Plants, January 2010, pp. 26-31, in the American Nurseryman or heard his recent presentations you know he is on a sustainability roll and he has opinions about native plants and what constitutes an invasive plant. This panel discussion sounds like fun. As always the OSU Nursery Short Course offers a great program.

Dr. Amy Fulcher starts her faculty position at the University of Tennessee, Knoxville November 1st. She will be the Sustainable Ornamental Plants Extension/Research faculty member of the Department of Plants Sciences (previously Plant Sciences and Landscape Systems). In the future you will be able to find her new e-mail address at http://plantsciences.utk.edu/faculty.htm. That she will be missed is a gross understatement. I do not know of anyone so dedicated to nursery production and the people that own, manage, and work in nurseries. Her passion is expressed by her excellence. Congratulations Amy; your excellence is recognized in Kentucky and far beyond its borders.

Ever since I saw a picture of the fruit of a female Sassafras albidum on the cover of Wharton and Barbour’s Trees & Shrubs of Kentucky I wanted to get a picture of my own. Well, every year I was too late. I was going by resources that said the fruit ripened in August, even September. This year I altered my morning walk several times a week to pass a female plant in a thicket. Then I found another plant with better foliage nearby. Sassafras albidum fruit are a blue-black drupe with a red pedicel. Resources often say the fruit ripens in August or September but these images were taken July 30 & 31, 2010. Image 1, Image 2, Image 3.

I just could not help this premature announcement so I could put Amy Fulcher’s new title in print:  Dr. Amy Fulcher will speak at the KNLA Summer Outing, Spetember 8, 2010, Ammon Nurseries, Burlington, KY on “A Horticulturist’s Perspective on Scale Pests of Woody Plants”  - This presentation will cover some of the scale pests that are surfacing in nurseries and landscapes.  Taken from a horticulturist’s perspective, the presentation will briefly outline each scale’s identification, lifecycle, potential to damage crops, impact on production and sales, integrated pest management-based control strategies, and how to stop scale pests before they get established at your business.  Novel control strategies will also be discussed.  Some of the scale pests that will be covered are Japanese maple scale, European fruit lecanium scale, calico scale, and oystershell scale.


From a reference UK diagnostian Paul Bachi found Half hours with insects by Alpheus Spring Packard dated 1877 the following appears which notes a species of apple borer which “is sometimes destructive to the apple, though the red maple seems to have been its original home.”

Dr. John Lindstrom, University of Arkansas, gave us some Amsonia plants to trial as part of the SERA-27 plant evaluations.  He has named it Amsonia ‘Blue Bridges’.  I have found this plant to be quite distinct with a large white terminal bloom with a bluish blush.  Ours stand about 30 inches tall.  Jon has also introduced Amsonia â€˜Big Jon’ a particularly tall Amsonia that we are just starting to test; the bloom seems typical but it is still in a container.  He gave us one plant, June cuttings rooted readily and we have enough plants for a landscape trial.


I was paging through Chlorophyll in His Veins by Bobby Ward to write a review and came across the description of xSinocalycalycanthus raulstonii â€˜Hartlage Wine’ Theodore Klein Plant Award Winner for 2009.


Itea virginica â€˜Theodore Klein’ seems to have a fatter shorter bloom that ‘Henry’s Garnet’.  Checked Dirr, 2009, and he agrees.  Also the foliage is nicer as I have observed and Dirr says “has shown the highest resistance to leaf spot and flea beetle in Zone 7.”  Thanks to the late Thom Harmon for giving out plants at a LNA meeting so I am confident I have the right plant. (my first one from a commercial source looks identical to ‘Henry’s Garnet’)

HortMemo has been kept up in recent years.


2,4-D continues to be a common herbicide used in the early spring when ornamental plants are most readily damaged. Recently I was reading Kentucky Pest News, March 23, 2010, and found in SHADE TREES & ORNAMENTALS the following very interesting articles.  The last one relates to a possible use of 2,4-D that could result in ornamental plant injury.  Let’s hope the protecting of pasture clover limits 2,4-D use near nurseries.

-Pear Fire Blight: Maryblyt Predictions Can Aid in Disease Management

-Boxwood Leafminers

-Eastern Tent Caterpillars Feeding

-Buttercups in Grazed Pasture Fields - ……Buttercups are short-lived perennials or winter annuals that produce shiny yellow petals in the early spring.  …..   If chemical control options are desired, most herbicides registered for use on grass pastures that contain 2,4-D, dicamba+2,4-D (eg. WeedMaster), aminopyralid+2,4-D (ForeFront), triclopyr (eg. Crossbow, PastureGard), or metsulfuron (eg. Cimarron) will effectively control this plant. However, legumes such as clovers interseeded with grass pastures can be severely injured or killed by these herbicide products. For optimum results apply an herbicide in the early spring (early March or April) before flowers are observed, when buttercup plants are still small and actively growing. For best herbicide activity wait until daytime air temperatures is greater than 55 F for two to three consecutive days. 


I read in an e-mail from Mark Halcomb about Jim Robbins’, University of Arkansas, Newsletter called Arkansas Re-leaf Newsletter for the Commercial Green Industry.  This edition can be found at http://www.aragriculture.org/News/ReLeaf/2010/march2010.pdf or you can go the archives http://www.aragriculture.org/News/ReLeaf/default.htm and look at any or all his newsletters.


So are we interested in the Ipad?  While I have no experience with it other than picking one up and finding it heavy, the credit card apps for Iphone some use to offer credit card transactions  (when infrequent use or bank costs have made it impossible) have been made available for the Ipad.  This application may be handy for small businesses that want to provide for credit card purchases on site (nurseries being able to make transactions out with the customer instead of walking back to the office or at a small retail center or Farmer’s Market/Flea Market).  Not to recommend any one over another when I do not use them but you might check what is possible by visiting https://squareup.com/ and https://squareup.com/features for a review see  http://techcrunch.com/2009/12/01/jack-dorsey-square/n a quick search of ITunes shows other services are available.

Bernheim Arboretum and Research Forest Vistors’ Center designers won EPA's Lifecycle Building Challenge which recognizes innovative green building ideas to reduce environmental and energy impacts of buildings and assists the building industry in reducing more than 88 million tons of building-related construction and demolition debris sent to landfills in the United States each year. The Professional Building category was won byKira Gould, William McDonough + Partners, Charlottesville, VA for their design of Bernheim Arboretum and Research Forest Visitors' CenterThe visitors' center design roots the building firmly in its woodland context by blurring distinctions between the indoors and outdoors, and by incorporating the surrounding forest into the building's lifecycle analysis. Construction emphasized safe, closed material loops of biological nutrients, which break down to safely return to forest soil; and technical nutrients, which can be remanufactured into new objects. The mechanical connections and reconfigurable modules allow for building alterations. The project performs 51% better than the ASHRAE-compliant base case used to measure the greenhouse gas reduction.  Kira Gould, William McDonough + Partners, Charlottesville, VA also won the Best Greenhouse Gas Reduction award sponsored by the American Institute of Architects Committee on the Environment (COTE) for Bernheim Arboretum and Research Forest Visitors' Centervisitor center.  William McDonough is the co-author of Cradle to CradleBernheim Facebook Page contained this information and lead to: http://www.epa.gov/greenbuilding/pubs/lbc3.html#winners

FROM:            Win Dunwell, Extension Horticulturist

SUBJECT:      Miscellaneous Information and Announcements.


Chris Summer described Tsuga canadensis 'Scotty Perry' as his pick for LNA Plant of the Month for September 2009.  I took some images of it and with them and a written narrative of what he said and posted them


I was visiting with Mitchell Leichhardt and learned of an extremely fragrant David Austin Rose ‘Gertrude Jekyll’ that was growing in his garden.  The rose is named for the great garden designer Gertrude Jekyll (pronounced JEE-kÉ™l), a rose fancier who wrote Roses for English Gardens that is available free online.  I am not sure if a large shrub rose is everyone’s cup of tea but the flower is very pretty and the true rose fragrance is worthy.  See here.


I was embarrassed to learn the seed pod on a plant in Heritage Seedlings stock block that I asked Mark Krautman, the Stewartia specialist, to identify was Stewartia pseudocamellia.  I guess I need to evaluate Stewartias for west Kentucky to see which survive, bloom and produce seed.  Currently we have none in gardens.  Thankfully, being older, I am not longer afraid to ask what something is and just smile at the embarrassment having learned something in the process.  Mark told Dewayne Ingram and I while at his nursery that he liked the Carpinus betulus â€˜Pinoccheo’ that is lakeside at Bernheim.  Dirr mentions that plant and that is was from Arborvillage, Holt, MO and there is a specimen at the JC Raulston Arboretum.  Anyone have it?  Why is Pinocchio in the Carlinus name spelled with an e?  Mark mentioned the means he uses to select his plant product mix along the lines of J.C.’s rationale: 1. Be a nursery plant; 2. Easy to propagate, grows well; 3. Has values consumer wants.


Mark Elzinga of Elzinga & Hoeksema Greenhouses a bedding plant grower, has developed the New Millennium Greenhouse production site with a $4 million investment in geothermal, solar, wind, and energy-efficiency technologies to grow organic produce.  In his presentation he said there were “a lot of snake oil salesmen out there” so one had to study, learn --- “Sustainability is a continuous journey, it is constantly changing—“.  And while his business is “profit driven” he has made his employees into a “green team” constantly checking for ways to improve.  Most of his technology is applicable to ornamental plant production and he applies as much of the technology as possible to produce his bedding plant crops.

On the drive to the KNLA Summer Outing I saw the biggest planting of Eupatorium purpureum, Joe Pye weed, ever at around mile marker 80 along the south side of the West Kentucky Parkway.  The plants are thick for several miles in the areas disturbed to move the tree line back from the road bed. There was a diversity that was incredible some of the heads where probably 3 feet high.


If you are interested in “Making Cents”; Charlie Hall has a blog http://ellisonchair.blogspot.com/  that is pretty useful.  You can subscribe and get the updates as they are posted.  I find it to be a very professional and interesting.


And so I have joined the social networking environment.  I am just getting started and have yet to really learn how to make the best use of Twitter and Facebook.  I think Twitter will be the primary site I will try to post to with some regularity and you can get to it at http://twitter.com/WDunwellUKNCDC


I went to the Far West Show and while wandering through the new plants booth was surprised to see Mike Haymen’s Nyssa ‘Hayman’s Red’, Red Rageâ„¢ featured.  People got to vote on which plants they liked the best from the many in the area.  I also saw Tom Ranney’s Hydrangea arborescens Invincibelleâ„¢ Spirit Hydrangea, Hydrangea arborescens 'NCHA1' PPAF CBRAF

Introduced by Proven Winners® ColorChoice® Bred by Dr. Tim Ranney, North Carolina State University, Zones 3-9, Available as liners from Spring Meadow Nursery, Inc. in Spring 2010 and some nurseries will have #1 and #2 containers available in 2010.  Check it out at http://www.colorchoiceplants.com/invincibelle.htm or my picture from a smaller plant in the show.


I was also intrigued by Keith Warren’s Carpinus ‘Wireless’ for under powerlines.  It flat tops if not forced to a central leader. 


While we are on-line I learned a lot about e-marketing garden centers from Phil Adikes’ presentation. I have since put some of my web pages on Google Analytics to monitor usage.  Phil’s presentation was animated and very interesting.  I will use some of what he and Bridget Behe presented on my site.  I will share a few bullets in future issues and on Twitter.  Phil’s site is  http://gardencenternews.com

Mike Dirr’s new Sixth Edition of the Manual of Woody Landscape Plants: Their Identification, Ornamental Characteristics, Culture, Propagation, and Uses is now available. As soon as I heard this great news from Bill Fountain, UK Professor who teaches woody plant identification, I ordered a copy from Stipes Publishing. So far I have noticed a few changes; a favorite plant of Tony Nold, the late Buddy Hubbuch, and Ben Cecil, Euonymus sachalinensis (fr. Schmift), is now E. planipes (Koehne) and a plant given to me as part of a Will Witte plant distribution at the 1993 Southern Plant Conference in Chattanooga, TN as E. japonicas â€˜Bekkomasaki’ not listed in the last “Dirr’s Manual” is listed in this one as E. japonicus â€˜Benkomasaki’. I have given credence to Mike and changed the label. I believe Will said he got his from J.C. Raulston Arboretum in 1987. And so it is, I have had it in my hands just one day and already looking up my favorites and moving my comments from the last edition to this one. Fun stuff!


The American Society for Horticultural Science met in St. Louis this week and I was interested by several presentations (will mention others in a later HortMemo) one that caught my attention was by Henderson, KY native Kyle Daniel, OSU Graduate Student with Hannah Mathers and Luke Case. To quote a statement in the abstract “Roundup Original and Roundup Pro exhibited the greatest number of cracks between all Genus of trees, while the Kleenup Pro and Scythe exhibited less cracks. This could be attributed to the increased surfactant contained within the Roundup products.” We have been discussing this issue in the past; at Amy Fulchers IPM Workshop 2008 I based part of my bark cracking presentation on Dr. Hannah Mathers ONLA March 2008 The Buckeye article “Let Them See Their Mothers: Eluding the Roundup Tragedy”. Dr. Mathers in essence r ecommended to minimize Glyphosate Injury: 1) Use Glyphosate with no adjuvant load. 2) Calibrate Spray Equipment. 3) Apply the correct amount of Glyphosate. 4) Two passes in rows to prevent overspray. 5) Take extra caution spraying near thin barked trees. I have posted her Table 1. Registered Glyphosate Products 2006: that tells whether a product has an adjuvant load or not.


I visited Forest Keeling Nursery while in St. Louis for the ASHS meeting. We grow our oak seedlings in a pot that is 14 inches long they grow theirs in a 2.5x2.5x2.5 inch pot including giant seeded ones like Bur Oak. I was impressed by the size of their plants in a short time. It was a great tour with Wayne Lovelace, his daughter Kim and container grower Lupe. Visiting his seed orchard soon to be spaced at 40 feet between trees told me I need to space out my “Gilbertsville” willow oak orchard (6’ centers).

WATCH FOR - Poison Hemlock: A Growing Concern in Kentucky, an article by J. D. Green in Kentucky Pest News calls for another spring use of 2,4-D besides the treatments for Roundup-resistant Marestail, Conyza Canadensis, (see Martin and Witt, http://www.uky.edu/Ag/kpn/kpn_02/pn020520.htm)  that have increased spring spraying of 2,4-D resulting in distorted plants, losses due to aesthetically unsaleable plants, loss of growth (normally a season), and a lack of uniformity in plantings.  J. D. wrote in KPN, number 1200, June 16, 2009, “In grass pastures and hayfields herbicide products containing 2,4-D can be effective when applied to young, actively growing plants in the rosette stage of growth. Spot treatments with products containing 2,4-D, triclopyr, or glyphosate can also be used depending on the location.”  I like the mention of spot treatments and that glyphosate is effective and would be preferred to the volatile 2,4-D for control of Poison Hemlock (Conium maculatum).

'Milano Maraschino', H. 'Milano Rocket', H. 'Milano Violet Mark', H. 'Octavian Cherry Doll', H.  'Octavian Exotic Marble', H. 'Octavian Glow', H. 'Octavian Marble Model' and H. 'Octavian Marble Ring'.  We would also like to have his Chrysanthemum 'Milano Pink'.  The Octavian precursor in the name indicates a diploid daylily and the Milano means the plant is triploid.

The UK and OSU Half-Rate Pesticide Application for Nurseries Workshop is July 14, 2009 at Green Ridge Tree Farm, 6100 Bardstown Road, Elizabethtown, KY 42701. To see the program and registration form go to PDF iconhalf-ratepestwrkshp2009.pdf


We need you to complete a pest management survey at http://tinyurl.com/KYipmsurvey in order to make developing a multi-state pest management strategic plan a success. All Pest management survey responses are anonymous and kept confidential. 


The nursery crop group at the University of Kentucky is working with a regional group of Extension specialists from GA, SC, NC, & TN to survey current pest (insect, disease, & weed) management practices and current pest priorities of growers in southeastern, wholesale, ornamental nurseries. The project is funded by the Southern Region Integrated Pest Management Center (SRIPMC) and supported by the Kentucky Nursery and Landscape Association (KNLA) and by each cooperating state’s nursery and landscape trade organization. 


This insight into current and emerging pest priorities will allow research and Extension professionals to design their programs to investigate and resolve the most pressing pest issues in the green industry. 


Your time and effort to complete the survey will allow us to develop a multi-state crop profile (CP) and pest management strategic plan (PMSP). The pest management tools produced will be available in print and on-line.


Completion and submission of the survey is implied consent.  All responses are anonymous and confidential. Your efforts will benefit you, as well as benefit other growers in Kentucky and the southeast.

Thank you for your time to fill in the survey from the Regional Nursery Science Working Group: Amy Fulcher and Dr. Win Dunwell, University of Kentucky; Drs. Anthony LeBude, Joe Neal, Kelly Ivors, and Steven Frank, NCSU, and Craig Adkins, NCSU Cooperative Extension; Drs. Sarah White, JC Chong, and Steven Jeffers, Clemson University; Drs. Matthew Chappell, Kris Braman, and Jean Williams-Woodward, University of Georgia; Drs. Alan Windham and Frank Hale, University of Tennessee.


The IPM Nursery Crops workshop held at Oldham County Extension Office and River Farm Nursery was fantastic. Dr. Dan Herms exposed some myths such as – recommending fertilizing plants to increase resistance to pests when research has shown that the plant trades energy for pest resistance for growth. Dr. Greg Schwab, UK Soil Scientist shared information about soils and nitrogen enhancers being using in agricultural applications. Amy Fulcher the program organizer and presenter talked about Nitrogen basics. Then to River Farm Nursery where Pat Carey had set up demonstrations including allowing for scouting his nursery and digging a huge hole in the ground so Dr. Schwab could show and tell about fragipans and their influence on crop production. This program was definitely “worthy” as reported by all in attendance including me.


It is with regret that I announce that Dr. Gerald “Jerry” R. Brown, retired University of Kentucky Professor and Fruit Extension Specialist passed away May 30, 2009. Jerry was truly special; following a bicycle accident that left him a tetraplegic he showed a remarkable resilient spirit. Over the years we at the UKREC would look forward to hearing from Jerry and his visits and attendance at our functions were special treats. We will and do miss him; we promise to keep his memory alive.

The Nursery Crops IPM 2009 Workshop with Dr. Dan Herms, Entomology OSU, Amy Fulcher, UK Horticulture and Dr. Greg Schwab, UK Plant and Soil Science will beThursday, June 4, 2009; 0800-1600. The Workshop will start at the Oldham County Extension Office, 1815 North Highway 393, La Grange, KY 40031-8632, 502.222.9453 and end with hands-on scouting at River Farm Nursery.  CEUs have been applied for. The contact and organizer of this meeting is Amy Fulcher, 859.257.1273 e-mail afulcher@uky.edu, for program and registration information and form: PDF iconnurserycropsipmworkshop.pdf


Amy Fulcher sent out an e-mail about --- “the UK Nursery Crops program working in collaboration with USDA and Ohio State University to implement air blast sprayer calibrations and a half-rate pesticide program.  This is a program that has been widely successful in nurseries in Ohio and has saved growers money due to reduced pesticide costs as well as has tremendous environmental benefits.  We will be hosting a program at a central KY nursery (TBA) on July 14 th, 2009 and want to invite growers and extension professionals from all crops that use air assisted sprayers to participate.  I will send promotional material in a month or two, but I appreciate any mention of the program that you can make in newsletters in the way of a “save the date”.”  Once again CEUs will be applied for. 


Eastern Region International Plant Propagator’s will have their annual meeting in Cleveland, OH.  ER IPPS is soliciting propagation or production practice posters for this meeting.  The poster chairman is Vern Black, Bailey Nurseries, Inc., 1325 Bailey Road, St. Paul, MN 55119: 800.829.8898 x 360 Fax: 800.829.8894; e-mail: vern.black@baileynursery.com I have posted the form and instructions online at PDF icon2009ippsposterforms09.pdf

Does anyone grow or know anyone who grows Platanus x acerifolia 'Sutternii' ? (Earl Cully, Heritage Trees, Inc called in that Jason Tabor of Anna Nursery is growing some from materials Earl supplied)


I previously mentioned enjoying the late plantsman J. C. Raulston’s sabbatical travelogue archived in the Friends of the NCSU Arboretum Newsletters http://www.ncsu.edu/jcraulstonarboretum/publications/newsletters/newsletters.php In the process of reviewing the new 2009 paperback edition of Dan Hinkley’s 1999 The Explorers Garden: Rare and Unusual Perennials I found on his website equally interesting travelogues and essays /


I got a chuckle reading the great article Cultivating plants and Friendships in the February 2009 Digger magazine on Roger and Arda Berryhill’s 46 years running their Berryhill Nursery that we have visited with UK Horticulture and Landscape Architecture students several times. The reason for the chuckle is Arda is quoted “I suppose a lot of us in the nursery business would be more successfully financially if we didn’t love plants so much.” true or not? Your call. She also indicates that “Changes in market, technology drive the industry”: stating that they started their business with the then new technology of container growing; now do more pot-in-pot and have recognized recent demand for natives. In the same Digger there is an article by Elizabeth Peterson Customers turn to what’s green in which she states “Sustainable living, staying at home and growing your own food are among the hot trends for 2009.”


In the process of logging in to the Green Industry Knowledge Center I thought what a great resource for the Kentucky nursery/landscape industry. On the Home page one reads “We are an interdisciplinary group of research and extension professionals who are dedicated to provide you with up-to-date, unbiased information on a range of production issues associated with the commercial nursery and greenhouse agricultural industries. Our Mission: To provide best management practice information for the cultural production, technological and engineering challenges which producers and industry professionals may face, growing ornamental crops in the eastern region of the United States. Our Vision: To help nursery and greenhouse growers and allied industries stay informed, improve production practices, protect the environment and maintain profitability.” The many resources can be found at http://www.waternut.org/index.html

Plants in the UKREC Botanic Garden: I have been surprised that we still have an Euonymus japonica â€˜Bekko Masaki’ it is now about 15 years old and looks great and in spite of repeated winter freeze damage, it tolerated the April 2007 freeze and is now 4 foot tall and 18 inches wide in the shade of a Cornus mas â€˜Spring Glow’ we got from J. C. Raulston that is a “pride and joy plant” with it’s 2 months of yellow winter bloom. I grew an Idesia polycarpa from seed I picked up at Wave Hillmany years ago. It has not produced the fruit it is known for and has suffered dieback in the poor soil, open sun environment. My “precious” Carpinus turczaninovii I got from Lee Squires, Cave Hill Cemetery was so severely damaged by the April 2007 freeze that it was removed in the fall of 2008. The branch tips of our Lagerstroemia fauriei â€˜Kiowa’ were damaged by the April freeze but have grown out. The wonderful exfoliating cinnamon bark of ‘Kiowa’ is spectacular and makes it worth growing. ‘Kiowa’ has not impressed us with it’s short season white bloom. We are really excited that Paul Saunders, the man who distributed boxwood cultivars for the National Boxwood Trials and prepared Boxwood: Choosing the Best, National Boxwood Trial Report 2006, stopped by with plants to add to our boxwood collection.

There is a plan to use ‘Silver Cloud’ Redbud as the cover image for the 2008 UK Nursery/Landscape Research Report. I was investigating the variegation of the leaves and remembered Dr. Bob Geneve explaining “jumping gene” variegations to me. I decided to include that in the image description and here it is: Cercis canadensis â€˜Silver Cloud’ – Silver Cloud redbud is an outstanding Theodore Klein selection found in his nursery field of seedling redbuds. The white on green foliage is striking and holds up reasonably well through the summer. The variegation observed in Silver Cloud redbud is most likely the result of a “jumping gene” caused by a transposon. Transposons are pieces of DNA that move from one location to another on a chromosome. If the transposon moves into a gene important for pigment production, that cell is unable to produce that pigment. The resultant irregular patterns show up as blotches, dots, irregular lines and streaks. Dr. Barbara McClintock, won the 1983 Nobel Prize for describing this pigment variegation in corn grains.

Ginko info: I was talking with Bill Johnstone and Richard Wolford at an LNA meeting about the many names attributed to the horizontal rambling ginko they found when cleaning out some old nursery rows at Miss Lillard’s some years ago.  I have heard Ginko biloba â€˜Horizontalis’, Ginko biloba â€˜Wolford’s’ and just “that one Richard puts into his landscape designs”.  Bill and Richard came up with Ginko biloba â€˜Noble’s Horizontalis’.  Richard propagates his from cuttings and lets them go from the ground frequently as multiple trunks while others, such Ben Cecil of Sunnyray’s Nursery, are growing them from grafts and training to single trunks like the one at Bob and Pat Hill’s Hidden Hill Nursery.


The SNA Trade Show is moving from a summer show to a winter show for 2009.  It will be February 12-13, 2009 at the Cobb Gallery Centre, http://www.cobbgalleria.com/.  I have not found any information posted to the SNA website < http://www.sna.org/> but anticipate it soon.


The cost of Soybean Cyst Nematode (SCN) testing for the nursery certification program has been increased to $100.00.  The increase is to provide technologies that can confirm that the cyst nematode found is actually SCN and not one of the many other cyst nematodes that are not involved in quarantines.  If you need to certify that your nursery fields are free of SCN take a regular soil sample for a free SCN test to your county Extension office.  If the result is that there are cyst nematodes present do the SCN nursery test to confirm that the nematode(s) found are in fact SCN.  Special thanks to Drs. Paul Vincelli and Don Hershman for their efforts to make this test more accurate.


Stephanie Tittle asked me about gardens to visit in Spain.  Her request struck a cord because I have been reading the late J. C. Raulston’s narrative of his 1988 European traveling sabbatical and I was actually just starting his Spain adventure.  For those that have not read J.C.’s narrative it is a great read if you enjoy visiting gardens.  He starts out in the Friends of the Arboretum Newsletter Number 18 September 1988 issue with “---I briefly sketch some of the experiences of my university “Sabbatic” (sic) leave.”  “Briefly” it isn’t at what must be 150 pages, but a fun read all the same which includes some interesting personal accounts.  His introductory statement is a truism as far as I am concerned, he wrote “One of the wonderful things about visiting gardens is that every garden has its unique special points of interest – no garden can contain all plants for all ages, nor any one visit encompass the range of interest which varies throughout the year (a show of my forgetfulness this quote was used in HortMemo 5).  So even if one has experienced the “great” gardens: Kew, Sissinghurst, Longwood, etc. – “minor” gardens, even an individual private home garden, always have something special and unique to offer the observer which has never been seen before.”  The narrative is in J. C. Raulston Arboretum Newsletters 18-22 and they can be found at http://www.ncsu.edu/jcraulstonarboretum/publications/newsletters/newsletters.php

Extension Office (Shelbyville) site eliminated.  For more info contact Amy Fulcher, 859.257.1273, afulcher@uky.edu or Win Dunwell, 270.365.7541 x 209, wdunwell@uky.edu


UK Horticultural Twilight Tours will be July 31, 2008 at the U.K. Horticulture Research Farm (Man Of War and Nicholasville Road, entrance off Man of War west of Nicholasville Rd onto Emmert Farm Lane), Lexington, Kentucky. For more information contact UK Department of Horticulture’s Pam Compton at 859.257.2909 or her e-mail pscomp1@uky.edu.  

I just read in GPN Greenhouse Production News about Hemerocallis Ruby Stella.  The article had it in quotes as ‘Ruby Stella’ but the United States Patent 20050193452 says it is “varietal name ‘BERRUB’. This new variety is also sold under the trade name RUBY STELLA (Breeder's Ref. No. D 92-54).”  Trying to make me crazy.


I was labeling slides and looked in Allan Armitage’s Herbaceous Perennial Plants 3rd Edition and learned that Cimicifuga racemosa is now Actaea racemosa.  Allan says a James Compton paper in 1998 started it all.  While accepting of the changes Allan writes “Personally, I dislike it, and have trouble understanding the rationale, however it looks like the changes are here to stay, so let’s get with the program.  Here we go, welcome to the wide, wide world of Actaea.”   For me I had to go back and re-label my old images, while doing so I decided the images were no good, deleted them, and went out to take new images.

Scouting Nursery Crops, Thursday, July 10, 2008, at Shelby Co. Extension Office (Shelbyville) and Wilson Nurseries, Shelby, Co.  For more info contact Amy, 859.257.1273, afulcher@uky.edu


I recently had the good fortune to attend a professional meeting of the Southern Extension Research Activity - SERA 27. The group “focus is the identification, evaluation, selection and dissemination of information on superior environmentally sustainable landscape plants in nursery crop production and landscape systems in the southeast.”  There is always a tie-in with touring nurseries and gardens to look at special plants.  The late great J. C. Raulston wrote â€œOne of the wonderful things about visiting gardens is that every garden has its unique special points of interest - no garden can contain all plants of all ages, nor any one visit encompass the range of interest which varies throughout the year. So even if one has experienced the "great" gardens: Kew, Sissinghurst, Longwood, etc. - "minor" gardens, even an individual private home garden, always have something special and unique to offer the observer which has never been seen before.”  So it was with some excitement I postponed HortMemo 5 until I returned from this year’s SERA – 27 meeting in Richmond, VA hosted by Virginia Tech and organized by Drs. Alex Niemiera and Dr. Rumen Conev.  So what does on learn in a day’s tour?  We were surprised to see that Liberty Elm performed badly at the Maymont Garden with limb breakage and trunk splitting.  Peggie Singlemann, Director of Horticulture, is replacing the Elms with ‘Princeton’ elms. We observed the Princeton Elms looked healthy, but they are not that old yet.  Comments relative to the “new” elms were shared including the statement that ‘Valley Forge’ wants to be a shrub and requires some doing to train to a tree form.  I was able to score images of Osmanthus fragrans blue fruit; not a plant I have seen in Kentucky.  At the Great Big Greenhouse Garden Center, Doug Hensel told us that tropicals were a large part of his business, people were looking for plants certified organically grown, and water conservation was linked to the use of natives.  Butch Gaddy of Colesville Nursery, shared that larger material was a trend in supplying his east coast landscape contractor customers; a trend I observed at the MANTS show in January.


Allan M. Armitage’s long awaited third edition of Herbaceous Perennial Plants: A Treatise on their Identification, Culture, and Garden Attributes is on the store shelves.  The wait since the 1997 2nd Edition was worth it.  Allan says of it; “I love this book; I love seeing it in peoples’ hands, on bookshelves, in retail garden center, on coffee tables, and worn out and tattered in the garden”.  I love it, too; it is bigger in every way.  A larger format but not so much as to limit it’s handiness.  It contains more entries, more pages, more pictures, and a few deletions.  The deletion I noticed was the elimination of images for plants with names starting with K; most notable is Kniphofia.  Allan’s “Some Thoughts of the Author” are worthy and fun.  Some examples: First up is “I asked myself why was I doing this.  -----.  The reasons are many, but the only one that counts is ‘Because I want to’”;   and – “---, books will never go away, and a good book becomes a friend.”; or  “If the internet changed anything, it is not what we read but how we buy.”; “Regardless of where one gardens, two things become self-evident.  The first is that soil preparation is half the battle.  The second has to do with the plants one selects”; and he goes on “– half the fun of gardening is to try plants that are not supposed to grow here”; and on garden design, a design technique we share, “I can usually be found with a trowel in one hand and a potted plant in the other, searching for any empty ground in which to put the sucker.” And so it goes, Allan is a great plantsman and a great man that most know as a friend even people who have never met him.

Amy Fulcher is planning her annual Scouting Nursery Crops program for Thursday, July 10, 2008, at the Shelby Co. Extension Office (Shelbyville) and Wilson Nurseries, Shelby, Co. Randy Zondag, Lake County, Ohio, Nursery Specialist, will be on the program with other production specialists. For more info contact Amy, 859.257.1273, afulcher@uky.edu


The Nursery/Landscape Sustainability conference/program is still in the planning stages if you have any input please contact, Win Dunwell, wdunwell@uky.edu or 270.365.7541 x 209.


The Woody Plant Seed Manual, Agriculture Handbook No. 450, is on-line. Mark Halcomb, UT Area Nursery Specialist sent out the news. The two editions (1948 and 1974) are some of the most coveted books in Ornamental Horticulture. I am so excited, I would love to have a copy of the complete new edition in my hands and on my bookshelf next to the other two, but this one I can access from where ever I am without dragging a large heavy book with me and it will be constantly updated as information is added. Mark wrote “Apparently, they are in the process of updating the manual, but rather than waiting for the new version to come out, they are posting the new information to the web version as it becomes available. Here is the main web site -- http://www.nsl.fs.fed.us/wpsm/. If you click on genera, you can find details on germination requirements of specific plants.” Happy Days!


Cicadas are coming to Kentucky. They will appear Statewide, except for Purchase and possibly Pennyrile areas. ENTFACT-446, Periodical Cicadas In Kentucky is available at http://www.ca.uky.edu/entomology/entfacts/ef446.asp

Schedule notes by Lee Townsend appeared in Kentucky Pest News Number 1152, February 11, 2008." Here are a few significant dates from a study of the emergence of this brood back in 1991 at Robinson Forest by Dr. Paul Kaliz, UK Forestry Dept. Emergence began on May 4 with wide spread activity by May 10. There was a 9-day difference between dates of peak emergence from upper south slopes and lower slopes. The last nymph was caught leaving the soil on May 31. The last adult was heard calling on June 16, apparently there was no answer."

From Nursery Notes for April 30, 2008 by Mark Halcomb I cut and pasted the following “Periodical Cicadas will visit some places in May. If you had cicadas 17 years ago in 1991, you can expect them to return soon. They will emerge when the soil temperature 4 inches deep reaches 64 degrees. The males begin a high pitched singing 4 days after emerging. Their dry empty skin is found attached to branches. It is impossible to prevent the damage the female does to pencil size branches as she lays her eggs. The wound will later resemble a zipper. Cicadas emerge, sing, mate, lay eggs and die. Pesticides are ineffective since they do not eat. They can lay many eggs, damage many ornamentals before they encounter sufficient pesticide to die. They may live 4 to 5 weeks. Nursery fields surrounded by woods will have larger populations since they have already spent 17 years sucking sap from tree roots."

I was looking for a web site for Allan M. Armitage after realizing my Books link to a faculty UGA site was no longer working. I found GOLD at Armitage Images; http://www.armitageimages.net/ for those in the plant game check it out!!! It is not only images of herbaceous plants but includes grasses, trees, and shrubs.


While you are at it, for those interested in native plant and wildflower propagation see William Cullina’s page at HM08.html#HortMemo">http://www.williamcullina.com/ He is the author of an excellent resource The New England Wild Flower Society Guide to Growing and Propagating Wildflowers of the United States and Canada, (Houghlin Mifflin, 2000)


National Arbor Day is celebrated on the last Friday in April which is April 25, 2008 (Arbor Day Foundation http://www.arborday.org/index.cfm).


I am curious if anyone has had any experience with Cornus xrutgerensis â€˜Rutlan’ (Ruth Ellen®) Dogwood. I saw one I really liked at the Morris arboretum. Someone had told me it wasn’t special. If you have comments to share send me an e-mail wdunwell@uky.edu or call 270.365.7541 x 209 (comments are KNLA Nursery Views Spring 2008; Paul Cappiello says it is prone to disease, more so than other of Dr. Elwin Orton’s hybrids).


I was preparing a plant presentation and rummaging around in The Year in Trees by Kim Tripp and late J. C. Raulston when I came across a penciled note “Buddy Hubbuch likes it a lot” looking over to the underlined plant in question I found ‘Henry Hicks’ (Magnolia virginiana cv.). So out to the UKREC Magnolia collection to see how ‘Henry Hicks’ compares to ‘ Green Bay’. At the UKREC in Princeton, KY ‘Green Bay’ is spot free while the old foliage of ‘Henry Hicks’ has small black spots, otherwise for this winter they both have had good evergreen foliage all winter. The Magnolias in general look great even ‘Jon Jon’ that was killed to the ground in the 2007 April freeze has flower buds opening.


So far I have not received any nominees for the 2009 and 2010 Theodore Klein Plant Award. The committee will meet after the spring rush so please send in any nominations you have to wdunwell@uky.edu thanks.

OK, HortMemo is actually coming out a few days after February 29th. I just had to keep the once every four years date.


I was reading Horticulture magazine and came across several good, even great, articles. Paul Cappiello wrote about Don Shadow in both an informative and eloquent fashion. I particularly liked the “ -- Tennessee twang so sharp it could slice the shine off the mornin’ dew.” I checked, this pub is not available on-line at the Horticulture Magazine site but C. Coleston Burrell’s publication series on Invasive Species and alternatives to them are on-line at http://www.hortmag.com/article/The_Invasive_Problem1/ and http://www.hortmag.com/article/the_Invasive_problem2. Another article was interesting because I was not aware of the Wister Award for Daffodils and searched the web site of the American Daffodil Society site and found that the award normally given once a year had 9 daffodils awarded in 2007 and 2 in 2008; so I must assume they are trying to catch up or there has been a lot of breeding work going on in recent years. Those for 2008 are 'Brackenhurst’, a red and yellow large-cupped daffodil and 'Hawera’, a miniature yellow triandrus hybrid with several blooms per stem.


To recommend nominees for the 2009 and 2010 Theodore Klein Plant Award selections please e-mail or call Win Dunwell, wdunwell@uky.edu or 270.365.7541 x 209. The committee always ends up with many more than we can award so it is a difficult decision and frequently we hear - why didn’t such & such win; it has to be on the list to be considered.


I went to Bernheim Arboretum on February 27th and it started snowing but with cell phone guidance from Tony Nold I found the Acer henryi I spoke of in last months HortMemo. The plant I observed was similar to others I have seen; a multi-trunk plant about 20-30 feet tall with light-gray bark. The branch angles make for a slingshot provider if I ever saw one. It is near and behind a redbud on the sun shade trail. I forgot to document the redbud name but will report that later.


So many plants, so many great plants people, so many gardens and arboreta, so many nurseries and garden centers, so little time: I must hurry. Thankfully, we have many wonderful places worthy of a visit within a day trip of where any Kentuckian lives. See Plant Study Sites web page for information.

And so it is that Dr. Robert “Bob” McNiel fully retired January 31, 2008, maybe, he will still be teaching in the department this semester. I have been inarticulate when speaking about the many wonderful years Bob and I have shared with Bob Geneve, other faculty and all the great students.  I frequently give Bob credit for “saving me” from the mid-career slump by inviting me so many years ago to travel with he and the students.  Those worldwide travel experiences: seeing the great nurseries, landscapes, gardens, arboreta, with a few cultural locations mixed in for good measure got me excited about knowing more about ornamental plants, all of them, not just the woodies I was partial to, and plant use and production, and the peoples and cultures of the world.  The production part and plant development has always been a great part of the learning process for all who traveled with him; visiting Jellito in Germany when our friends Alan and Mary represent the company in the US and are right here in Kentucky and J. Frank Schmidt on the west coast when their representative is UK Dept of Hort. Alumni Kit Shaughnessy.  Of course, his students enjoyed the hard working teacher; their mentor and friend; someone to learn from and even share a joke with; even if the joke might have been at his expense.  I find myself continuing to be inarticulate. As Mark Krautman, Heritage Seedlings, always tells our students – “You have to have the fire in the belly”, the passion for what you are doing, and Bob always has had that!  I guess what I would like to ask is that you share your stories about him with others let’s make Dr. Robert E. “Bob” McNiel one of the legends.

The Mid-States Expo and MANTS proved to be great learning experiences.  I really was excited to see that the Moffitt’s had Acer henryi on the Snowhill Nursery, Shelbyville, KY plant availability list at Mid-States.  I want one of the cold hardy (at Bernheim for many, many years) small trees approximately 30 feet or less with attractive trifoliate foliage that Mike Dirr says emerges red. In Maples of the World -- A. henryi was listed as rare in cultivation; of course, that was published in 1994. The pendulous racemes of “usually sterile” seeds are stunning as they emerge green then turn red and the yellow-red fall color is considered beautiful, but I have never observed it. I will make a point of it this year.  Once I was on to Melvin having the A. henryi I made a point of checking to see what every one had and to talk to people about the good stuff. I found a great tight small Boxwood that was very interesting and I heard a rumor about a new Acer truncatum cultivar that sounds good; I will let you know when I get the word on that one.  I noticed at MANTS that the clientele walking the halls were looking to see what booths had that was unique; some thing they were not already getting from suppliers they had long-term business relationships with.

I have added several book reviews to my web site Ornamental and Environmental Horticulture Books.  Several recent books have become valuable resources, in particular: Ronald L. Jones’ book Plant Life of Kentucky: An Illustrated Guide to the Vascular Plants contains a lot of information relative to native and naturalized plant status in Kentucky and a good identification resource; L. Katherine Kirkman, Claud L. Brown, and Donald L. Leopold’s Native Trees of the Southeast: An Identification Guide.


In anticipation of separating the 2007 from 2008 and beyond from my HortMemo Upcoming Meeting list I have tried to update it to include the winter meetings of importance. If you know of any I should add please let me know.   

I recently had the good fortune to hear a seminar by Dr. Marc van Iersel, Professor, Plant Nutrition and Physiology, University of Georgia at UK. His work with annuals and some woodies is enlightening. During rapidly-induced drought plants are under measurable stress, but plants subjected to gradually-induced drought are able to acclimate. Dr. van Iersel’s web site is informative and his grower-oriented and many of his research publications are available for viewing at: http://mvanier.myweb.uga.edu/ I particularly liked his site Fertilization in Greenhouses: an Introduction http://www.hortphys.uga.edu/fertilizer.html

Tom Priddy, UK Ag. Weather Center reported in a recent UK E-mail ...Bluegrass Joined Central in Severe Drought; East and West Remained in Extreme Drought... The latest Kentucky Drought status is available at: http://wwwagwx.ca.uky.edu/latest_drought.shtml Many of us were fortunate to attend the KNLA Summer Outing and hear Tom Priddy talk about the Spring freeze and the 2007 weather/environment. What a season I was out trying to collect seed and found that my prized Spicebush colony had dried up during seed development resulting in immature seed and dead leaves still on the trees that are now putting out new leaves and blooming.


Cicadas are coming: In 2008 brood XIV (17 - year) will appear statewide except Purchase and possibly Pennyrile areas. For more information see Drs. Doug Johnson and Lee Townsend’s EntFact-446 Periodical Cicadas in Kentucky publication at http://www.ca.uky.edu/entomology/entfacts/ef446.asp Pesticides are listed in the publication but pesticide recommendation updates with additions and deletions to this 2004 publication can be expected from the Entomology Department as we get closer to the Summer 2008 emergence.


Jeremy Griffith, Extension Associate, has been searching for new sources of pine bark and in the process has investigated use of freshly harvested pine bark and the whole tree chips as a media versus the aged pine bark most in west Kentucky are using. He reports that there several differences between aged pine bark and fresh. Pine bark in general is preferred over hardwood bark because it contains less leachable organic acids and resists decomposition than some hardwoods. The characteristics of pine bark are dependent on the method of composting and age. Growing plants in fresh pine bark media increases competition for nitrogen. Pine bark will absorb or ‘fix’ ammonium nitrate so that it isn’t available to the plant. As the pine bark is aged the C/N ratio is reduced dramatically. This causes the substrate to need less nitrogen, making the majority of N from fertilization available to the plant. Fresh pine bark averages 10%-15% available water while aged pine bark averages 25%-35% by volume. With age it becomes less water resistant and can absorb more water within each particle. The change in water holding capacity allows the grower using aged pine bark to irrigate with less frequency than if fresh pine bark is used. These characteristics make aged pine more desirable than fresh pine for west Kentucky growers.

1- 1936 8.34 | 2 - 1930 8.37 | 3 - 1913 11.33 | 4 - 1999 11.94 | 5 - 1925 12.38| 6 - 1964 12.45 | 7 - 1904 12.53 | 8 - 1988 12.67 | 9 - 1952 12.76 | 10 - 1911 12.77| 11 - 1902 12.94 | 12 - 1944 13.00 | 13 - 1921 13.07 | 14 - 1901 13.22 | 15 - 1914 13.33|

In another e-mail he wrote: How does this summer's heat and lack of rainfall compare with the past? A preliminary check indicated that this has been the 3rd driest May through August in the past 113 years. With only 10.41 inches of rainfall for the state so far from May to August 26th...The only drier May - August's were 1936 with 8.34 inches and 1930 with 8.37 inches. After this year's near record dry summer, the next driest was 1913 with 11.33 inches. Last Thursday's US Drought Monitor holds 73 percent of Kentucky in Extreme hydrologic drought. ...it's the 13th warmest May thru August in the past 113 years. WOW! Unfortunately, plants in the brown-tan landscapes of west Kentucky make all this seem obvious.


SNA Researcher’s Conference 2007: Field grown trees did not respond to nitrogen source or even fertilizing with nitrogen in a study by Jim Robbins of Arkansas. Discussion about this presentation at SNA found that other university researchers had similar results. John Ruter found reduced foliar nutrients and root dry mass when container plants were fertilized above 2 pounds of nitrogen per cubic yard. Italian visiting researcher Piero Frangi found similar results to Ruter’s: excess fertilizer lead to an increased shoot to root ratio (less roots) and less drought resistance. Richard Beeson has done work on container irrigation and spacing for years; his presentation on spacing showed results that a spacing of 0.75x (x = pot diameter) was most efficient. There were numerous papers on whole tree media; chipping whole pine trees and using the material as media. I cannot wait to get the CD sent to all SNA members with all the great research papers and posters that were presented this year.


The 2007 KNLA Summer Outing kept in the long tradition of successful Summer Outings with over 60 exhibitors, 200 plus attendees; standing room only for the interesting education presentations with good audience interaction; a great Paul Cappiello plant tour; Yew Dell tours and a good lunch. See you next year.

The new SNA Best Management Practices (BMP) Manual, to be called BMP 2.0 will be available from The Kentucky Nursery and Landscape Association this Summer and can be pre-ordered by contacting Betsie Taylor, KNLA Exec. Dir., 350 Village Drive, Frankfort, KY 40601; 502.848.0055 or 800.735.9791; Fax, 502.848.0032; e-mail, knla@mis.net ; url, http://www.knla.org  The content of the manual has been reviewed by more than a dozen university personnel, as well as the Atlanta office of the Environmental Protection Agency (EPA).  The following new sections have been added to BMP 2.0 : 1.) field production; 2.) nutrient management planning; 3.) several “How To” procedures; and 4.) a new section of web site references.  With field production added this will pretty much be the “Must Have” manual for all nursery operators/owners.


The Eastern Region International Plant Propagator’s Society is hosting an area meeting in Crestwood KY this July 23-24, 2007.  The meeting planned by Amy Fulcher with a little help from her Kentucky Horticulture friends will focus on Plant Propagation, Production, and Restoration Ecology.  Join us for an afternoon of tours followed by a welcome reception/book signing at Boone Gardiner Garden Center's new location on Monday and a full day of presentations from nationally-recognized experts and authors on Tuesday.  If you have questions contact: Amy Fulcher, 859.257.1273, afulcher@uky.edu; Paul Cappiello, 502.241.4788, paulc@yewdellgardens.org; or Win Dunwell, 270.365.7541 x 209, wdunwell@uky.edu


Plants continue to show signs of recovery from the April freezes.  Unfortunately the only plants I seem to have lost are what I consider my favorites: Acer triflorum (which was infested with Granular Ambrosia Beetle) and a Styrax obassia the other one is fine.  All in all  non-stressed (no disease, insect or nutrient problems) landscape sized plants seem to be doing ok; small recently propagated or planted plants seem to have suffered the most.  We will monitor plants as we progress through the growing season.


The Kentucky Nursery and Landscape Association /Kentucky Department of Agriculture Nursery/Garden Center Tour will be August 1-3, 2007 to Indiana and Michigan this year and promises to be another worthy event.  Contact: Betsie Taylor, 502.848.0055; e-mail, knla@mis.net or Bill Holleran, 502.564.4983; e-mail, bill.holleran@ky.gov

The freezing temperatures, with a low forecast for 23oF Saturday or Sunday, are expected from April 4 to April 8, 2007.  Flower and flower bud damage and possibly some new growth and even wood die back can be expected.  Amy Fulcher wrote in Nursery Update #54 that the Degree Days for April 2, 2007 were significantly higher than for 2006.  April 2, 2007: Lexington 290, Princeton 389.  April 2, 2006: Lexington 130, Princeton 250.  Wow!  Plants are far advanced for this time of year and are not in a physiological state to tolerate freezing.  For an indication of flower bud hardiness on fruit and fruit related plants see ID-21, Disease and Insect Control Programs for Homegrown Fruit in Kentucky Including Organic Alternatives, 2005; pages 18-19 at <http://www.ca.uky.edu/agc/pubs/id/id21/id21.pdf >


Mark Halcomb, University of Tennessee Area Nursery Specialist put out a recent newsletter on Frost Protection: The Sad Story.  

Dr. William â€œBill” Fountain sent out an e-mail about the cold injury that has occurred and what home gardeners should do about the impending doom of the very low temperature forecasts.


An Eastern Region International Plant Propagator’s Society Area Meeting will be held at Yew Dell Gardens July 23 & 24, 2007 with Tours on Monday, July 23, 2007 and the program on Tuesday, July 24, 2007.  The program includes special emphasis on native plants for restoration, landscape, & ecology.  Amy Fulcher has lined up some great speakers.  As information develops we will share it via HortMemo or you can contact: Contact: Amy Fulcher, 859.257.1273, afulcher@uky.edu; PaulCappiello, 502.241.4788, paulc@yewdellgardens.org; or Win Dunwell, 270.365.7541 x 209, wdunwell@uky.edu

Dry Pesticide Rates for Hand-held Sprayers HO-83 by Joseph Masabni is a very helpful publication that takes into account that chemicals have different weights and densities and ready transfer of conversions to tablespoons per gallon does not work.  See  <http://www.ca.uky.edu/agc/pubs/ho/ho83/ho83.pdf>


Recently I received a question about getting tags for white-tailed deer population reduction. I called Shane Bogle, Caldwell County Extension Agent for Agriculture and Natural Resources and learned from him that you should contact the Kentucky Department of Fish and Wildlife Wild Regions and Private Lands Biologist for your area (see <http://fw.ky.gov/kfwis/viewable/privatelands_biologists.pdf>) for a property evaluation on the best method for managing nuisance deer populations. Ross Hunter used the following publications for his research work on controlling deer rubbing in nurseries: Managing White-tailed Deer Problems in Kentucky by Dr. Thomas G. Barnes, UK Extension Wildlife Specialist <http://www.ca.uky.edu/agc/pubs/for/for57/for57.htm> and Wildlife Damage Management Fact Sheet Series:White-Tailed Deer by Paul D. Curtis and Kristi L.

CANCELLED: The Controlling Deer in Kentucky Nurseries that was scheduled for Tuesday, March 6, 2007 from 9:30 am to 3:00 pm at the Steve Weatherford Farm in Clinton, KY has had to be cancelled due to no one registering to attend. If you have an interest in this topic please contact Win <wdunwell@uky.edu> or Christi <cforsyth@uky.edu> and register your desire to attend a program to prevent injury from deer rubbing.

Once again Brent Wearren and crew at Wearren and Son Nursery have provided a great educational opportunity by hosting the winter pruning workshop, February 13th. It was a rainy cold day following other rainy days that made the fields impossible to drive in and very difficult for walking. Brent had the crew cut down trees from the field and bring them to a sheltered area for demonstration. Ultimately we did go to the field for a valuable pruning demonstration but equally important Brent shared that the pesticide manager would not be happy to see Brent’s deep footprints in the clean area in the tree row because pre-emergent herbicide had already been applied and now there would be areas without the herbicide barrier. Interesting comments by Brent and his crew: when retraining the central leader with masking tape don’t pinch the tape closed in between the new leader and the old leader as it will hold water and rot the new leader; when cutting a leader slope the cut to ensure water runs off; rake clippings into the mow lane so they are not in the tree row and covering the ground limiting herbicides getting to the ground target; Brent insists there be a “game plan” for all pruning with the first year the most important; for winter-early spring pruning prune the fastest growing plants first; bleeders like maples and yellowwood are last even left til late spring-early summer; selecting the central leader is a pruning crew job, not a staking crew job; plants that may need staking such as oak, prune first then stake in order to get even branching; the obvious, but not always practiced - plants with a lower profit margin should not be a priority but a fast growing plant that is selling well like Autumn Blaze Maple should get special attention to guarantee a quality finished plant. These are just a few of the tit bits shared that make each and every pruning workshop of value and you have other people that have pruning responsibility sharing how they do it like Tom at Snowhill sharing his method of training buds to produce a new leader. You just have to be there!!! A special thank you to Amy Fulcher for organizing these events.

The American Hemerocallis Society has prepared a press release: Listing Hemerocallis fulva as an Invasive Species. I first heard about this at a workshop on invasive species at the Eastern Region International Plant Propagator's Society meeting in Grand Rapids, MI and have since read the publication in The Michigan Landscape November 2006 issue and online at http://www.daylilies.org/pressreleases.html To quote directly from the release: "Several state and agency publications and websites list Hemerocallis fulva as an invasive species. Unfortunately there appears to be some confusion in properly identifying the rhizomatous H. fulva species and setting it apart from the non-invasive, clump forming hybrid daylily cultivars. To lessen the confusion, The American Hemerocallis Society encourages use of the following definitions to clarify the difference between H. fulva species and the hybrid daylily cultivars which are excellent garden plants: Invasive Species: Hemerocallis fulva(Common names: Fulva, Tawny Daylily, Common Orange Daylily, Roadside Ditch Lily, and Tiger Lily). H. fulva is an infertile triploid daylily which does not set seed but does spread by rhizomes. If left unattended it can form large colonies over time. Alternatives: Alternatives include any of the thousands of commercially available hybrid daylily cultivars which are clump forming and non-invasive."

in the nursery. It is truly a small world. Also, while in Taian, China I attended the 4th China Taishan International Trade Fair of Flowers and Nursery Stock. It was well attended and had lots of interesting booths with some of the most expensive orchids (small green flowered) I have seen anywhere in the world displayed.


Question: Is anyone growing 45 gallon pot-in-pot containers? If so, I would like to talk to you about your experiences with that size and the size of the plants being grown. Also, has anyone had an experience with growing 3 inch trees in 25 gallon pot-in-pot? I would like to talk to you as well.

The WKNLA Summer Meeting was held August 29, 2006 from 6:00 to 8:00P at the McCracken County Extension Office. It was a good meeting where Ross Hunter, Extension Associate for Nursery Crops and Terri Gater, Nursery inspector for west Kentucky were introduced to those present and all participated in the sun damage to the face evaluation. The Purchase Area Master Gardeners prepared a wonderful meal of heavy hor de oeuvres. Dava Hayden is planning training sessions for those that would like to take the PLANET Certified Landscape Technician exam next year this would equally benefit those taking the KNLA Kentucky Certified Nurseryman exam in January. You can contact Dava at the McCracken County Extension Office by phone 270.554.9520 or email: dava.hayden@uky.edu


The KNLA/KDA Bus Tour, July 31-August 2, 2006 to nurseries in Ohio was a great educational and sharing experience. Some of the more interesting things were the green manure cover crops used in field nurseries. We saw corn at several nurseries; let it tassle, mow it, then plow it down. Buckwheat and composted leaves were highly recommended at two nurseries and there was the normally encountered Sudex and soybeans. We learned a great deal about handling and growing perennials at Millcreek a very well-run nursery with happy employees. As stated previously any tour with Bob McNiel is worthy. The response from those that did attend was let us do this again next year! Bob is already planning the 2007 KNLA tour to be more diverse by adding upscale garden centers to this years mostly production tour so we can learn more about the retail end of the nursery/landscape industry. The rumor is that the 2007 tour may go to Indiana and Michigan but I guess we will just have to wait for Bob and Betsie to share the itinerary.


The 7th Annual KNLA Summer Outing is just days away. It will be at Yew Dell Gardens, on Friday, September 22, 2006 . A few days ago I got to visit Yew Dell and the newly renovated Gheens Bank Barn and new Peyton Samuel Head Trust Pavilion is a great facility for Ozzie Johnson of It-Saul Plants, Atlanta, Ga. to give his presentation entitled: The Truth About How Those Great Plants Got Here.

It is with great sadness I must acknowledge the recent loss of the Kentucky nursery industry’s dear friend and avid supporter, Bill Young. I have worked with Bill Young ever since I came to Kentucky. For a number of years I was a Trade Show Chairman; thanks to Bill’s persistent recommendations each year the trade show improved. I always looked forward to seeing him at the Louisville Nursery Association meetings where he worked so hard to ensure the continuing success of the monthly LNA meetings and ultimately would work equally hard for The Kentucky Nursery and Landscape Association. Thankfully, I enjoyed conversing with Bill at the May LNA meeting at Maple Crossing Nursery and corresponded with him very recently; he wanted my old LNA directories so he could copy them and have them in his historical files. He will be missed! Bill's obituary is in the Louisvile Courier Journals Obits Archives of July 01, 2006. http://php.courier-journal.com/obits/

The new Nursery Inspector Ms. Terri Gater will be housed in the UKREC Entomology Laboratory the University of Kentucky Research and Education Center, Princeton, KY. Terri will serve as a Nursery Inspector for the western half of the state, and is supervised by Dr. John Obrycki, Chair of the Entomology Department. The other Nursery inspectors are Joe Collins and Carl Harper in the Entomology Department in Lexington. Terri comes to us from a similar position in Florida. She will be a valuable asset for the Kentucky nursery industry.

At the second June Pruning Training by Brent Wearren and crew of Waterford Valley Nursery those in attendance were once again at a true educational experience. Ornamental tree pruning was a optional afternoon session that was brief but equal to the morning in knowledge gained by those attending. In addition to pruning, pest management methods were shared and discussed. All spoke highly of Amy Fulcher's, Extension Associate for Nursery Crops, diligent efforts to provide educational opportunities for the industry through her Nursery Updates and workshops.

2006 is the 100th anniversary of Longwood Gardens, http://www.longwoodgardens.org/, of Kennett Square, Pennsylvania. With the anniversary come several books of interest to those who would like to know more about Longwood Gardens. The first is a book that I read many years ago after my first visit to Longwood; A Man and His Garden: A History of Longwood Gardens: The story of Pierre S. du Pont's development of Longwood Gardens by George E. 
Thompson, Sr., 1976, published by Longwood Gardens. With the anniversary year there are two books that highlight the greatness of Longwood and it's plant exploration program. The first is Longwood Gardens: 100 Years of Garden Splendor: 1906-2006 by Colvin Randall, with photographers Gottlieb Hampfler, Richard Kenn, Larry Albee and Rondel Peirson published by Longwood Gardens. It is a picture/text book of the history of Longwood Gardens and it includes a DVD that is a presentation with narrative of the contents of the book. The second new book and the one that interested me the most is Plant Exploration for Longwood Gardens by Tomasz Anisko published in 2006 by Timber Press, Portland, OR. It is fitting that this book has been published as Longwood Gardens is celebrating its 100th year anniversary of the gardens and its 50th anniversary of Longwood's plant exploration programs. Seeing the greats: John Creech, Dick Lightly, and so many others in photos and the descriptions of their explorations makes this an entertaining and enjoyable read; knowing some of the plant explorers makes it all the more rewarding to see their legacy honored. That the book honors those that have gone before and those plant explorers of today makes it "worthy".

Speaking of plants in the Agricultural Research magazine for December 2005 there was an interesting article "Introducing Lycoris to U.S. Flower Lovers". I have Lycoris squamigera and L. radiata at the UKREC Botanic Garden, the first from my own yard and L. radiata from Brent Heath and we love them. But the article talks of rare species collected by Mark Roh of the USDA-ARS Floral and Nursery Plants Research Unit. These species were collected in Japan, Korea, and China. L. incarnataL. chejuensis, and L. flavescens have been added to the collections at the National Arboretum and are being tested for hardiness. If the picture of L. aurea and L. houdyshellii are any indication of these collected species, life will be better in the garden.


The KNLA West Kentucky Chapter meeting program and meeting was very informative. In addition to all the activities related to Kentucky and US legislation there were discussions related to PLANET and ANLA. The speaker for the evening was Sergeant David Caldwell, Kentucky Vehicle Enforcement: Region One. Sgt. Caldwell gave a great program on commercial and farm vehicle requirements, limitations, and vehicle enforcement. His presentation was factual, serious, and humorous thanks to the many questions generated by the audience. Most of the information in his PowerPoint presentation can be found at http://transportation.ky.gov with a lot of the information from http://transportation.ky.gov/dmc/licenses_authorities.htm

Allan M. Armitage - Armitage's Native Plants for American Gardens. This book is great. Thank you Allan. Allan's books always have an interesting introduction worth not passing over before skimming the book for that special plant. I was surprised to find the "propagation is slow and difficult" comment tied to Spigelia marilandica. It is an accurate assessment of seed propagation, the typical propagation for perennials and natives, but with Dr. Sherry Kitto's (University of Delaware) work on cutting and tissue culture propagation being applied commercially Spigelia is now readily available
(4 trays - 288 plants from AgriStarts III have grown very well and Spigelia has moved from specialty nurseries like Margie Jenkins, LA to Carolina Nurseries, SC that has it available in 8 inch pots in significant numbers). I harp on Spigelia because it is such a great Kentucky Native that makes a rounded plant about 24" tall with numerous uniquely beautiful yellow- throated red flowers in late Spring-mid summer. For more on Spigelia propagation.  All in all, the Spigelia thing is petty, the book covers some of the "best of the best" natives currently available for landscape use. A "worthy" book in my assessment. (Timber Press, 2006)

Who was Dr. Don Egolf? At the2005 Southern Plant Conference in Louisville, KY there was a discussion between Dr. Margaret Pooler of the National Arboretum and Dr. Mike Dirr of the University of Georgia about Dr. Don Egolf that lead to Mike saying the late Dr. Egolf was the greatest plant breeder of all time. I found this on page 540 in Dr. Mike Dirr's Manual of Woody Landscape Plants 5th Edition; "Dr. Don Egolf was one of the greatest woody plant breeders that history will ever recognize. He was a scientist, breeder, horticulturist, plantsman, and gardener traits that allowed him to introduce only the best. His plants will withstand the test of time. Like masterpieces of great artists, writers, and musicians, Dr. Egolf's plants stand out from those of mere mortals. As a young assistant professor at Illinois, I met and shook his hand, was able to attend several lectures, and voraciously read his cultivar releases in Baileya and HortScience. All young scientists and aspiring plantsmen should read his detailed descriptions of the new introductions. They leapt from the page into the reader's garden. Don Shadow told me that Dr. Egolf was endowed with the [sic] great eye for quality plants. With Hibiscus, Lagerstroemia, Malus, Pyracantha, and Viburnum “ Dr. Egolf produced magic. Our gardens are richer due to one man's vision and persistence. His woody plant legacy is without parallel." When someone of Dr. Mike Dirr's stature and reputation describes a person like that the words are an understatement. Mike, thanks for reminding us in print, I hope I get to read this statement in the 6th edition. (14Dec2011 - It is in the 6th ed. in the bottom paragraph on page 613; Mike, thanks for maintaining this wonderfully written tribute).

I recently read the Paul Cappiello and Don Shadow book Dogwoods and thanks to the Southern Plant Conference have both signatures in my copy. There is little debate that one of the most beautiful flowering trees in the world is Dogwood.
This book contains a large number of images of Cornus species and cultivars. The descriptions and information on cultivars is incredible but one of my favorites is that "Cornus florida 'Cherokee Princess' was selected by W. C. Higden of Mayfield, KY and introduced in 1959 by Ike Hawkersmith as 'Sno-white'. In 1963 it was registered as 'Cherokee Princess'". Cool! A Kentucky connection. The book is divided into six chapters: 1.) The Family Cornaceae; 2.) The Cornus canadensis Group; 3.) The Cornus alba Group; 4.) The Cornus alternifolia Group; 5.) The Cornus florida Group and 6.) The Cornus mas Group. I was born and raised on eastern Long Island so I enjoyed reading about Jim Cross and Bair Lustgarten, but the book is full of fun trivia; such as Mike Dirr preferring Snicker's Bars to the fruit of Cornus kousa var.chinensis this discussion lead to numerous taste tests on the Cave Hill Cemetery tour of the 2005 Southern Plant Conference in Louisville. My favorite quote from Mike Dirr on edible fruit of ornamental species is on Cornus mas "although edible, one must be hungry". I started out reading this book in a precursory fashion to write a review, ie. not reading all; then I found myself reading large sections, addicted to the mention of the greats Ernest Wilson, Mike Dirr, Jim Cross, J. C. Raulston, Polly Hill, Gary Handy, Barry Yinger, Kentucky's Higden, Gary Lanham, the now-Illinois Resident John Wachter, as well as, the late Theodore Klein. The book is a hardcover of 224 pages with 261 color photos, 3 black and white illustrations and the USDA Hardiness Zone Map. It fits more to the hand for reading than most of this day and age at 7.38 x 10.38 inches. Timber Press, 2005. For addition book reviews

I received the following. “We are in need of a new tree to serve as the Commonwealth Holiday Tree hereon the Capitol grounds in Franfort. The Norway spruce that we have used in years past was struck by lightning and the top is no longer attached to the trunk! We would like to find a Colorado, Engelman, or Oriental spruce of approximately 25'.

SUBJECT: Miscellaneous Information and Announcements.


Nursery Update #32 has been posted to the website below. Topics include More on Asian Ambrosia Beetle, Welcome to Bill Holleran, Tips for Managing Substrate pH, and the Scouting Report. 


The pruning workshop by Brent Wearren and company was an amazing educational opportunity. Every one of the 60 that attended were handsomely rewarded for their effort to get to Wearren’s rural nursery with hands-on pruning of nursery trees and information on a variety of nursery production related issues. Brent shared his process for getting quality liners to start with that make training the young trees easier and more efficient (more bucks to the grower) . Dividing those attending into groups of 12 and providing an English-Spanish speaking Wearren Nursery employee to train the Spanish speaking in attendance helped each attendee receive direct instruction in pruning techniques. Special thanks to Amy Fulcher, Extension Associate for Nursery Crops for organizing the event and to Brent Wearren for the effort to make it a true learning experience that will lead to quality nursery stock being shipped to landscapers and retailers resulting in more income to those producers that take advantage of what they learned and ultimately a positive impact on their employees and Kentucky’s economy. To Brent the Gene Ryan Award for taking time to share information that benefits the nursery/landscape industry as a whole (the late Gene Ryan readily shared with one and all and assisted me when I first came to the state as a “specialist”).


Kentucky Native Plant Evaluation report: For the first time we have observed a significant population of Spigelia marilandica, Indian Pink, seedlings in one of the UKREC flower beds that have Spigelia. We are pretty excited. The explosive dehiscence manner of seed dispersal had me anticipating we would have lots of seedlings but after almost 10 years these are the first in-the-bed seedlings we have noticed (we may have tilled them out with the winter weeds in the past). It continues to be one of my special favorites of the native plants we are evaluating and more Spigelia plants is always better. On the other hand the spreading nature of Monarda fistulosa, Bergamot, and Pycnanthemum pycnanthemoides, Hoary Mountain-Mint, is starting to cause some concern and certainly more work on controlling their spread. Monarda fistulosa’s susceptibility to powdery mildew and it’s aggressive spreading nature would have resulted in it being eliminated from evaluation and the display bed it is trying to take over if not for it’s wonderful ability to attract butterflies, honey bees, and bumble bees in large numbers. I have moved Cunila origanoides, Dittany, from the full sun field evaluation bed to the full sun display bed this year, it continues to impress me with it’s small rounded habit and long-lasting blue flowers. Our newest planting of Cunila origanoides is in partial shade and is leggy and not as dense as those in full sun.


At the KNLA West Kentucky Chapter meeting we talked about Sudden Oak Death, Emerald Ash Borer, Boring insects in general, Calico scale and pests on the horizon. In the May NMPro e-mail Todd Davis, NMPro editor reported this: New York’s Cornell Univ. identified a single specimen of Sirex noctilio, an Old World woodwasp, in a trap in Fulton, N.Y. This species has devastated up to 80% of pine forests in New Zealand, Australia, South America and South Africa. Federal and state agencies are setting traps trying to find evidence of establishment, according to Cornell. A beneficial nematode has been an effective biocontrol in the Southern Hemisphere.

I went looking for maps of TVA’s Lake Barkley, Kentucky Lake and Land Between the Lakes (LBL) and found the “Native Plant Selector: More than 140 plants native to the Tennessee Valley are featured on this site. It includes photographs and details about height, light preference, bloom time, and more. This list will expand as more native plants become available through commercial markets.” The “guide to plants suitable for landscaping in the Tennessee Valley Region” is there for shoreline owners wanting to plant a native plant landscape as riparian restoration. 


Our wildflower garden is small but continues to show that Polemonium reptans, Jacob’s Ladder and Trillium recurvatum, recurved trillium, are great Spring flowering plants with long flowering seasons. We are beginning to find that Phlox divaricata, Blue Phlox, is also a good garden flower. Our wildflower garden is in shade with a moist severely compacted clay soil that is slowly being modified by mixing the hardwood mulch in to the soil.

Baskin’s Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination an incredible resource recommended to me by UK’s Dr. Robert Geneve, co-author of the equally important and useful resource Hartmann and Kester's Plant Propagation, 7th Ed.; Rick Darke’s Timber Press Guide to Ornamental Grasses; the new Timber Press guides are abridged editions of encyclopedic originals in a handy format and size; L. Clarence Towe’s American Azaleas written for those that enjoy the ornamental and fragrant native azaleas; and Thomas G. Barnes and S. Wilson Francis’ Wildflowers and Ferns of Kentucky a very useful resource for all Kentuckians interested in our native flowering plants.

There was not a HortMemo 8.


An interesting discussion occurred between Richard Weber, Springhouse Gardens, and Teresa Ford the conifer expert - speaker at the KNLA Summer Outing. Richard was saying how he had not seen a catalog sent to him, actually his response was something like: I get hundreds of nursery catalogs; most end up in the garbage can. A sales approach/catalog needs something to attract my attention that your nursery is somehow special other than having: 1) superior quality; who would say in their catalog the quality of the plants were poor. 2) unique plants, doesn't everyone. 3) reasonable prices, would any say their prices are higher than their competition. So who has managed to get some of Richard’s business. He described a nursery salesman that stopped by, was enthusiastic and friendly and treated all at Springhouse as if he was thankful for their business even though he had yet to sell them anything. He always left a catalog with a special treat inside that caught Richard’s attention; ultimately Richard bought some plants from him and he kept right on with his visit routine now thanking all for the business and working to secure more. Richard concluded with a laugh that gifts of truly unusual plants always leave a lasting impression.


Back in February’s HortMemo 2 I announced that Kris-Ann Kaiser, President of the Murray State University Horticulture Club, was elected President of the Southern Region American Society for Horticulture Science Association of Collegiate Branches. Her recent election to Vice President of the ASHS ACB makes her an officer of national ACB <http://www.ashs.org/acb>. Congratulations Kris-Ann.

The variegated river birch from the same John and Danny Allen of Shiloh Nursery in Harmony, NC that discovered the Betula nigra 'Summer Cascade' see 2003 Hortmemo 8, is to be called Betula nigra ‘Shiloh Splash’.


The Kentucky Landscape Industries meeting January 12-14, 2005 has lined up some great speakers with the likes of Rick Darke, Carol Reese, Hannah Mathers and our own Ben Cecil, previously plant propagator for Bernheim Arboretum, now plant propagator for Imperial Nurseries in Quincy, Florida. These are just a few of the great speakers Dr. "Bob" McNiel and the KNLA Education committee have lined up.

Nursery Update #25 has been posted and the topic covered is diagnosing yellow leaves.


The 2005 Southern Plant Conference committee met on July 22, 2004 and the program and tours are lining up to make this the greatest Plant Conference ever. The Plant Conference will be September 8-10, 2005 in Louisville. The Seelbach is the host hotel and the tours will include Gainesway Horse Farm, UK Arboretum, Richard Weber’s Springhouse Gardens,<http://www.springhousegardens.com/gardens/> Yew Dell Gardens, Cave Hill Cemetery, Bernheim Arboretum, Seneca Gardens; outstanding plant study sites one and all. Betsie Taylor, KNLA Executive Director says the program and tours are “Awesome!”


FYI, plant problem diagnosis at nurseries frequently leads to speculation that poor survival and growth of liners is directly linked to planting too deep (it has been proposed by Dr. Donna Fare that growers should mark all liners with a brightly colored paint to show crews the appropriate planting depth.) Todd Davis’ NMPro e-mail newsletter comments that a “$400,000 project will address planting depth. Morton Arboretum in Lisle, Ill., is heading up a $402,254 project that will address planting-depth issues. A growing concern in the U.S. green industry is the premature death of landscape trees due to their roots being planted too deeply. The project, titled "Stopping Tree Losses from Buried Root Systems: A National Research and Technology Transfer Coalition" received $109,937 in federal grants, and the rest is funded by the arboretum. The project was announced as part of $1.16 million in federal dollars granted to 14 organizations to research and promote urban forestry. http://www.usda.gov/Newsroom/0241.04.html

At Amy Fulcher’s IPM Workshop in Elizabethtown on May 26, 2004 Cliff Sadof, Purdue University, gave a great presentation on economic thresholds related to insect injury on ornamental plants and consumer tolerance; John Hartman gave a presentation on using a computer model to predict the potential occurrence of plant disease and Mark Timmons of MTA gave a great presentation on managing for IPM (note: Amy has organized a second IPM workshop to be in Murray on August 3, 2004). Cliff Sadof’s web site is the first to come up when you type Landscape Entomology into Google’s search window. The site is http://www.entm.purdue.edu/Entomology/research/cs/ The information available from John Hartman can be found at the UK Plant Pathology web site http://www.ca.uky.edu/agcollege/plantpathology/PPAExten/ppaext.html and in the Kentucky Pest News http://www.uky.edu/Agriculture/kpn/kpnhome.htm Some points made by Mark Timmons are you have to be prepared, “timing is everything!”, to take advantage of the “windows of opportunity” that IPM activities such as monitoring and modeling offer.


For those growing ‘Summer Cascade’ river birch Dr. Tom Ranney’s, right-hand men Tom Eaker and Josh Mowrey recommend growing a serpentine form to five to seven feet to get a large head of weeping
branches. A plant trained to this form is in an image with ‘Summer Cascade’ founders John and Danny Allen at http://www.cals.ncsu.edu/agcomm/magazine/spring04/profit.htm At Tom Ranney’s site http://www.cals.ncsu.edu/specialty_crops/pubs/ranney.html there is a picture, in what looks like Tom’s backyard, of a ‘Summer Cascade’ trained to a central leader. We have both forms in trial at the University of Kentucky Research and Education Center nursery in Princeton, KY and will report our findings in the annual UK Nursery/Landscape Program Research Report. There is another Allen river birch, ‘Summer Splash’, being evaluated.


Richard Olson, NCSU graduate student told me that Dr. Egolf wrote in his dissertation that one of his goals was to develop a hardy fragrant evergreen viburnum. Let’s hope the hard work of the Ranney laboratory group at the NCSU Mountain Horticultural Crops Research and Extension Center is successful in achieving that goal.

May brings a great horticulture program, IPM: Practical Techniques for Nursery Crops with: Dr. Cliff Sadof, Purdue, sharing the results of his research in public gardens and garden centers showing consumer perception of plant damage and how it impacts sales. He will present how to develop an IPM program for nurseries and landscapes. Dr. Sadof has developed and published a list of economic thresholds for insect pests of nursery crops. Dr. John Hartman will lead a hands-on session to show how to use weather data to predict disease infection and more precisely time pesticide applications. Mark Timmon’s MTA Horticultural Consulting, Inc. spans the US and involves contracts with such companies as UPS. His firm develops and implements landscape IPM programs for large-scale apartment complexes. He is a nurseryman in the Louisville, KY area. Mark's presentation will focus on the "management" in IPM. The afternoon will take us to Green Ridge Tree Farm, one of the state's premier production nurseries, for a hands-on session involving all speakers. Key Plant-Key Pest, Pest Identification, Economic Thresholds, Biological Control, Resistant Selections, Scouting, and new invasive insects (especially emerald ash borer and sudden oak death) will be covered. IPM: Practical Techniques for Nursery Crops is approved for 6 Certified Arborist CEUs and 4 general and 1 specific pesticide CEUs (categories 1a, 3, 10, 12, and 19). Please sign up for the in-service and print and fill out the on-line registration form if you are planning on attending.

Sudden Oak Death quarantine was announced for Kentucky at the end of March 2004. Joe Collins wrote the Kentucky Nursery and Landscape Association the following: Kentucky has implemented a quarantine against all California grown nursery stock, effective immediately. There are several reasons behind this decision. First and foremost, because this disease is fairly new, not a whole lot is known about it. The USDA is currently regulating known host material, but this disease is continually found on new host material. Our office has consulted with plant pathologists and forestry individuals and we felt that it was in the best interest of Kentucky if we limit the amount of potential host material being introduced. One reason in particular is because red oak, a major tree species in our forests, is known to be susceptible to Sudden Oak Death.


In KENTUCKY PEST NEWS, Number 1017, April 19, 2004 http://www.uky.edu/Agriculture/kpn/kpnhome.htm John Hartman wrote “During recent weeks, Verticillium wilt disease has been discovered in some Kentucky nurseries growing 6 to 8 ft. maple trees supplied only a month before from an out-of-state grower. ---- Verticillium albo-atrum, is capable of causing a serious vascular wilt of a wide range of woody plants. Several of our common landscape trees such as ash, catalpa, katsura tree, magnolia, maple, redbud, smoketree, and tuliptree are susceptible to Verticillium wilt.” Please see his complete article for more information.

Volume 52 of the Combined Proceedings of the IPPS has arrived early this year and contains some great articles. If, like me, you are interested in native plant propagation see Rod Ackerman's The Propagation of Spianthes cernua, Ladies' Tresses Orchid or Sherry Kitto's Micropropagation of Trillium Species, pages 425-428 or Navarrete-Tindall and Erickson's Developing Techniques to Produce Native Warm and Cool Season Grasses and Forbs in Missouri, pages 429-434. An interesting article on hardiness in Buddleja indicates the reason we may have lost a large portion of our collection of 84 cultivars is because we were evaluating Buddleja for cut-flower production and harvested dried stems in the fall. The result of the study Time of Pruning Effects on Cold Hardiness of Butterfly Bush by Jennifer Warr, et al, at Auburn, pages 566-570, is that "Our study demonstrates that fall pruning of butterfly bush before plants have become dormant and conditions are still favorable for re- growth, increases the chance for low-temperature injury and possibly death." After 5 years of cutting Hydrangeas to the ground in October we have yet to suffer any such losses.

It is with great sadness that I must announce that Charlie Wilson, Wilson Nurseries, Inc., Frankfort, KY was killed in a car accident December 18, 2003. When I first met Charlie I thought who is this wild man, then I learned he might have been a little hyper, "always on", but he was no wild man, he was an intense businessman who was constantly reevaluating his business and his life. He moved his business forward to be better, more profitable, and yes, more fun, more exciting, more rewarding. In recent years he provided leadership for the industry as President of the Kentucky Nursery and Landscape Association and as President of the Kentucky Horticulture Council; he was willing to serve and persistently sought out knowledge that lead to new ideas, projects, and programs that would benefit his business and all in the green industry. After serving as President of KNLA he continued to serve as a mentor and providing his council to Executive Director Betsie Taylor. Betsie knew she could always call on Charlie. I cannot imagine a Kentucky Landscape Industries Winter Conference/Trade Show without Charlie's distinctive voice; his ability to always say the unexpected; a voice that frequently carried a laughing tone to go with his smiling face. 

A special thanks to Christi Forsythe for another year of efficiency, catching my mistakes, keeping me focused, producing HortMemo, and maintaining all the mailing lists.


Kentucky Landscape Industries, January 6-8, 2004, has added a Opening Night Reception which will be a great time for networking especially for those just getting started, see you there.

An interesting plant, Poliothyrsis sinensis D. Oliver, was found in the plants we put into our overwintering structure (covered but not yet sealed). For a long time there was no common name reported but Dr. Chris Briand of Salisbury Arboretum http://www.salisbury.edu/arboretum/Poliothy/PoSi/PoSiHM.html has it listed as chinese pearlbloom tree. It was interesting because I could not identify it at first (OK, it took me a month to figure out what it was. I had to see it at the Eastern Region IPPS silent auction to get an id..) and the fall color in a container was wonderful; it varied from a chartreuse to yellow to yellow with a red blush to dark red, even purple. Fall color for this plant in the landscape has been reported as yellow; Dirr says yellow-burgundy which sounds closer to what we saw, but I never trust bloom or fall color in a container plant as being representative of what one will see in the landscape. The plant was first discovered by the late-great Augustine Henry, whose home the UK Horticulture Club saw next door to Helen Dillon's Dublin garden. E. H. Wilson ("Chinese Wilson") introduced it to Arnold Arboretum, Boston, in 1908. There is a 12-15 foot plant in Bernheim Arboretum that I have seen in flower, white blooms on large inflorescences, in July. Stephen Sponberg reports it blooms in August to September in the Arnold Arboretum, but Mike Dirr has seen it in bloom in July at the Arnold. Sponberg says it is easily propagated by seed or softwood cuttings. I will plant our plant into the garden and see how it does. I believe this plant which lacks the fall red sepals of Heptacodium miconioides, seven-son flower, (I think I am learning why Heptacodium has canker problems; it leafs out too early in the spring and suffers freeze-induced wood damage) will be a good substitute summer-flowering small tree with good foliage, showy white bloom and excellent fall foliage. Every source I have lists it's zone tolerance as limited to zones 6 & 7, a pretty narrow temperate environment, anyone know otherwise?

Plants, plants, plants and more plants. While at SNA 2003... The World's Showcase of Horticulture®...I learned of several plants that have or will be entering the market. I have not evaluated any at this point. One of unknown hardiness that might fill a vacancy in Kentucky is Briggs Nurseries' yellow Rhododendron ‘Capistrano'; a "hardy" cultivar bred by David Leach. A Tom Ranney introduction Calycanthus ‘Venus' was seen in a publication at Don Shadow's booth. The awesome large white "magnolia-like" flower is stunning if the photo does it any justice (see at http://www.goldenleaf.org/Venusflyer.pdf), and here I was all excited about relatively large burgundy blooms of the Raulston allspice xSinocalycalycanthus raulstonii 'Hartlage Wine' that are puny compared to ‘Venus'. We have both plants in evaluation at the UK Nursery Crops Development Center, Princeton, KY. Another Tom Ranney plant that you may be aware of is Betulus ‘Summer Cascade', a vigorous easily trained birch for which Tom has prepared production protocols, http://www.cals.ncsu.edu/specialty_crops/pubs/ranney.html While in Don Shadow's booth I saw Chionanthus retusus ‘China Snow' (good name for a plant I really like). Don collected it years ago and his Japanese nurserymen friends really like it. It is a southern form with glossy foliage. And how about the awesome foliage of Hydrangea macrophylla ‘Lady in Red' on display in Mark Griffith's Propagation Nursery booth, . I have been infatuated with the late summer-fall foliage of ‘Pink Beauty' but ‘Lady in Red' seems to have a nice lacecap bloom and better colored fall foliage. While we're discussing the Michael Dirr hydrangea breeding program we had better mention Hydrangea macrophylla ‘Endless Summer' and the ‘Penny-Mac' hydrangea from the Atlanta garden of Penny McHenry. And from the US National Arboretum, Prunus ‘First Lady' a cross of Prunus okame x P. campanulata. Wow, more next issue of HortMemo.

Tony Avent's new book So You Want to Start a Nursery (Timber Press, 2003) includes lessons Tony has learned and his opinions on what it takes to operate a successful nursery. The topics covered are those that all nursery operators must address; the sooner, the better. I have always recommended new people learn all they can through study, visiting other nurseries, and building a network of resources over one or more growing seasons before putting a plant in the ground or in a container. Now I will add, and strongly recommend, that they read Tony's book as part of that learning investment. See my site Ornamental and Environmental Horticulture Books for a more thorough review and please note I have added it to the "Must Haves" list.

Amy Fulcher, Extension Associate for Nursery Crops, produced two Nursery Updates in June.


Dr. Bob McNiel lead a group of students, yours truly and other faculty on a grand adventure to the United Kingdom and Ireland in mid-May. As far as gardens go, Stoarhead and Bodnant were fantastic. We were surprised to learn that Irish nursery managers call the central leader training method of producing quality shade trees the American-form of pruning/training. We visited Pentland Plants http://www.pentlandplants.co.uk/index.htm a greenhouse operation that uses a transplanting machine, not remarkable in this day and age, but they had a replanter set up and operating. It was neat, it removed the media from cells that had no seedling and transplanted plants from a tray, resulting in a full tray of plants all done mechanically. I knew such machines existed, but this was the first one I had seen operating.

Whoops, I left off the web site for the Kentucky Pest News in HortMemo 4. It is http://www.uky.edu/Agriculture/kpn/kpnhome.htm In this weeks edition Mike Potter writes: Four serious pests of landscape trees: dogwood borer, bronze birch borer, flatheaded appletree borer, and honeylocust borer are beginning to emerge. The dogwood borer is the most serious pest of ornamental dogwoods, especially stressed trees in full sun. The bronze birch borer is a severe pest of white or paper birch, especially cultivated trees under stress. Flatheaded appletree borers are major pests of red maples, hawthorns, flowering crabapple, and several other hardwoods, especially those which are newly transplanted or under stress. Honeylocust borers are serious pests of transplanted and established urban trees with limited root zones. See http://www.uky.edu/Agriculture/kpn/kpn_03/current.htm for borer management and additional pest descriptions and management recommendations.

Since we last spoke Amy Fulcher has posted two Nursery Updates for 2003. As with past editions it tells you what is happening in west Kentucky nurseries and what you should be doing in the nursery now. 

Other newsletters with valuable information for the nursery/landscape professional are: Kentucky Pest News, published weekly during the peak growing season and bi-weekly the remainder of the year and posted to http://www.uky.edu/Agriculture/kpn/kpnhome.htm. The opening to the page states "The articles contained in the KY Pest News newsletter are submitted by the University of Kentucky College of Agriculture Entomology, Plant Pathology and Weed Science Cooperative Extension Specialists for a variety of pests including insects, diseases and weeds." and UK Inspector Findings in Kentucky by nursery inspectors Joe Collins and Carl Harper at like Amy they provide excellent images of what they are seeing out in the field and they have archived their newsletters so you can peruse previous years editions for an idea of potential problems you might encounter this season. Both are worthy


When Orson K. Miller, Jr. says in his Mushrooms of North America that the morel mushroom is common, I didn't expect to find the "choice edible" mushroom growing in our landscape mulch near the Rattlesnake Master I got from Richard Wolford several years ago. Richard, thank you!


The latest book I am reading is The Undaunted Garden: Planting for Weather-Resilient Beauty by Lauren Springer (Fulcrum Publishing 1994, I have the 2000 paperback). While I will always believe there is not enough compost on the face of the earth to make the soils near the building more that "backfill" of a most obnoxious kind, I do agree with her assessment that "a group of stalward plants" can make the difference between success and failure. Actually after 20 years of mulching the beds I believe most of our plants live in the "mulch media" on the soil surface. I will complete reviews of this book and Rick Darke's The American Woodland Garden in the next few weeks and post to the Ornamental and Environmental Horticulture Books.  The draft review of Rick Darke's book is there already.

Amy Fulcher has posted her first Nursery Update for 2003 to the web. 


Mark Halcomb and Amy Fulcher wrote an publication "Sweating Nursery Stock to Break Dormancy". This concept greatly increases the success in transplanting certain plants to the field or container. We have seen some plants in the field that seem severely stunted. The missed growth opportunity is costly.  Christi can mail out a hard copy if contacted by e-mail, cforsyth@uky.edu or phone, 270.365.7541 x 221 or Fax, 270.365.2667.

Drs. Stewart Warren and Ted Bilderback, North Carolina State University, will publish their research paper on cyclic irrigation in a future issue of the Journal of Environmental Horticulture. Dick Bir, Horticulture Extension Specialist, NCSU Mountain Horticulture Crops Research and Extension Center, Fletcher, NC sent out the abstract of that paper: Irrigation timing had a significant affect on plant growth, container temperature, and water utilization efficiency. Plants that were irrigated 1200, 1500, and 1800 HR (noon, 3 and 6 PM) significantly outperformed plants irrigated during early morning hours. Decreases in plant growth appear to be related to increase in diurnal water stress over the course of the growing season. Growers should avoid letting the container substrate dry out by late afternoon. Our data suggests that growers may want to investigate irrigating at times other than early morning.The research backs up the theory that cyclic irrigation can be used to avoid daily afternoon drought stress typically encountered from morning irrigations, but the first watering at 1200, noon, Wow!

Amy Fulcher, Extension Associate for Nursery Crops has published a newsletter Nursery Updatethat includes information that will be helpful year after year. Issues contain information on pruning, diseases, insects and other cultural practices.

The October Louisville Nursery Association meeting will be at Cave Hill Cemetery, 701 Baxter Avenue, Louisville, KY 40204 Wednesday, October 16, 2002. Events include tours and a hayride. Contact Jeff Perry, 502.267.5017 for more information.

I have seen a draft copy of the 2003 Kentucky Landscape Industries program and as always Bob McNiel has made it impossible to decide which of many great programs to attend. Allan Armitage (perennial plants), Allen Bush (perennials), Tracy Disabato-Aust (garden design), Ted Bilderback (fertilization and irrigation), Tom Shay (business management), Todd Lasseigne (plants), Bill Hendricks (plants), George Bottenberg (nursery pruning). Of course we don’t want to leave out Best Management Practices topic for 2003 being propagation, Pest Management Workshop (Initial and Recertification Workshop), The Garden Center Employee Workshop, The Landscape Design Workshop, and the Kentucky Certified Nurseryman Exam.

Casey Schott, 55, president and co-owner of Leichhardt Landscape Company and Garden Center passed away August 15, 2002 . He was one of the “enlightened ones”. During his tenure as president of the Kentucky Nursery and Landscape Association (KNLA) the Theodore Klein Plant Award was instituted and at his famous strategic planning sessions many current programs and activities of the KNLA were discussed. He and his wife, Cindy, embraced the elders in the industry and kept the late Willie Wilson and Mitch Leichhardt’s daylily breeding work going with their daylily nursery, Schott Gardens. They maintained the Wilson and Leichhardt daylily collections in their home garden and developed new cultivars for the landscape. He was generous, when the Wilson daffodil collection could not be sorted by cultivar he donated the bulbs to the University of Kentucky and those unknown but beautiful cultivars provide enjoyment for the Spring visitors to the University of Kentucky Research and Education Center (UKREC) Botanic Gardens, Princeton, KY and the UK Arboretum, Lexington, KY. He also supported the UKREC daylily trials program by providing many cultivars including those of the Wilson-Leichhardt-Schott breeding collaboration. Those daylilies have been divided and are now part of the collections at the UK Arboretum on the Lexington campus and several County Extension Gardens. A true artist: in his landscape designs; the garden he planned with Cindy and his sons, Mitch and Max; his work; and his life. He was an optimist and lifted those around him to his level of enthusiasm for plants, landscapes, art, outdoor activities, friends and family. A proud father and loving husband; he was always fair and honest, they just don’t come any better. Two of the many daylilies he gave me, BEST OF FRIENDS and YESTERDAY’S MEMORIES, are subtlety elegant in style; like him. He was a “best of friends” and will always be a part of “yesterday’s memories”. I will miss him.

In HortMemo 5 I wrote “Speaking of production systems demonstrations those at the Rhodo 2002, a regional garden display in Westerstede, Germany, were excellent http://www.kultur-und-gaerten.de .” Well, that was incorrect, we did not go to the Rhodo 2002 because it was not open while we were there. We went to the Landesgartenschau, Bad Zwischenahn, Germany. Doing a search for Landesgartenschau Bad Zwischenahn on Google.com and having the pages at http://www.lgs-bad-zwischenahn.de translated from German to English by Google.com (select - translate this page). I learned the Landesgartenschau would be open from 19 April - 06 October 2002 and the area described, “The central exhibition area of approximately 14 hectares with the topic gardens, the world-famous Rhododendronpark and the horticultural show landscape Weser Ems is in Bad Zwischenahn Rostrup, Elmendorfer road on the area of the Gartenkulturcentrums of Lower Saxony of the landwirtschaftskammer.” The maps of the Landesgartenschau on the web are very good I wish I had them with me when I was there. I apologize for the mistake and hope that those traveling to Europe this Summer and Fall get the chance to visit Landesgartenschau.

Herman Wallitsch, Sr., founder of Wallitsch Nursery, died June 11, 2002. He was one of the “good guys”. From the first time I met him when he hosted a greenhouse meeting in the 1980s til I last saw him at the 2002 Kentucky Landscape Industries Winter Conference he always welcomed me as someone he knew well and liked. He actually treated everyone that way and I hope many enjoyed the pleasant feeling of friendship he shared with all. He always took time to talk about things he had been thinking about. The press release said he was past-President of the Kentucky Nursery and Landscape Association and the Louisville Nursery Association, I suspect he was one of the “enlightened ones”, those that carry an association forward to new and better things. Herman will be missed.

So what should you be looking at in the Upcoming Meeting section? Well, September 7, 2002 is the KNLA Summer Outing at Bernheim, a “Worthy” event that I gladly shorten my long-time Labor Day family vacation in order to get home in time to attend. The Louisville Nursery Association meetings are always opportunities to see and hear about new ideas. The next LNA meetings are: July at Bill Lose’s Wholesale Nursery, Charlestown, IN; September at Chris Summer’s (“The best conifer grafter”says Paul Cappiello) Summers Nursery and Landscaping, Crestwood, KY and October at Yew Dell, Theodore Klein’s Nursery, Garden, and Homesite in Crestwood. What else? West Kentucky KNLA Chapter Summer Meeting, July 25, 2002. The Southern Nursery Association Trade Show and Researcher’s Conference August 1-4, 2002. For you “Plant people” don’t forget the Northern Plant Conference II, August 14-16, 2002, Eastlake, Ohio. And that is just a taste, check Upcoming Meetings for more.

It has been another mild (to say the least) winter and in traveling around the state I have seen plants of questionable hardiness creeping back into the standard product mix of some of the discount retailers. If you find clientele demanding these plants please be sure they know we have killed thousands of Ilex cornutaand I. convexa cultivars, Photinia x fraseri Red Tip has actually survived for several years in protected locations, but would not be a good plant for most sites especially considering it’s leaf spot problems.Lagerstroemia, Crapemyrtles have grown into tree form over the last few years but remember even in a mild winter for us they can be damaged and become the woody perennially cut-back as in years past. Of course, there are plants that while designated as zone 7 and higher in hardiness may actually thrive in our zone 6, so experimentation in your garden and even in the landscapes of your clients is still encouraged as long as all are aware of the risks. Personally, I have yet to place even a small percentage of all the wonderful plants hardy in Kentucky in my home landscape and UKREC Gardens. You might even use your knowledge of quality, hardy plants to competitive advantage in your KYAgr advertising cost-share promotional program with Hope Crain (see last month’s HORTMEMO).

A report on Dr. Bob’s Euro2002 “Worldwide” Tour. The “Worldwide” name was created during the 1stEurope trip (1994) to describe the full itinerary for each and every day with no breaks for “Shopping”, the “McNiel Evening Forced March” was named later, but is a part of every Dr. Bob trip. So how was Floriade? You ask. The once every 10 years world’s-fair type Horticultural show near Amsterdam was impressive. We were there during the flowering of many tulip cultivars. All the gardens built by the countries of the world were nice, there was even a children’s entertainment style garden that I think all adults found to be fun. The US Garden was called the American Quilt Garden http://www.amerigarden2002.com/ . The garden contained USA natives while keeping the quilt theme. Plants grown in patterns in trays where mounted on two upright panels. The pattern within the tray and that made by the different trays created the quilt pattern. The garden was designed by Thomas Wirth of Massachusetts. It was planted with American natives like IteaFothergillaTaxodium and others. It contained mirror walls that made a small part of the garden seem much bigger than it really was. Near the American Garden was a demonstration greenhouse with vegetable and cut flower production systems including the automatic moving benches that bring the flowers to the front of the greenhouse to be harvested (a technique we saw this Spring in Oregon). It was a very educational display. Speaking of production systems, demonstrations such as those at the Rhodo 2002, a regional garden display in Westerstede, Germany, were excellent http://www.kultur-und-gaerten.de . The model nursery demonstrations showed propagation systems, the care of Rhododendrons in the field nursery through production years to finished plant and the growing of street trees. Add in some fun gardens and being there when the Rhododendrons and Azaleas where in peak bloom and it was a great place to visit. The Rhododendron collection growing under a canopy of trees is huge. They also have a very large display bed of modern Rhododendron cultivars. We saw a lot of ornamental plant production and utilization while traveling with Dr. Bob McNiel in Europe and England. Of course, The Chelsea Flower Show was crowded as always, my favorite gardens this year were Marie Curie’s Garden of Discovery and the Celtic Sanctuary. Pleasant unexpected surprises on this tour were: the already mentioned Rhodo 2002; the Aalsmeer Historical Garden (Historische Tuin) http://www.htaalsmeer.org ; and Penshurst Place and Gardens, Tonbridge, Kenthttp://www.penshurstplace.com/

While in Oregon on a Dr. “Bob” McNiel planned and lead Hort student tour of the nursery industry and gardens we visited The Portland Japanese Garden http://www.japanesegarden.com/it is always a wonderful experience no matter how many times I have been there, this time a brief snow/hail storm added to the ambiance. The new Classic Chinese Garden in Portland was a pleasant surprise. I frequently wonder about Chinese Gardens found in countries other than China, but the Portland Chinese Garden http://www.portlandchinesegarden.org/home is excellent. It reminded me of those I have visited in Suzhou, China. Small, but “Worthy”! We, also, visited the young, but nice Oregon Garden built with significant nursery/landscape industry support. There is a Frank Lloyd Wright house on the grounds http://www.oregongarden.org/ .

Frequently we are asked what can UK do for the nursery/landscape industry. Talking with nurserymen, landscapers, and garden center owners/growers I have learned there is interest in: low-input field nursery production practices; pest management (develop a handy manual for the grower to assist with decision making); liner production, harvest, and storage; and new plants for the product mix. Are there any of the above you would like to add your support to it’s priority or do you have anything to add to the list, if so, please contact me by: e-mail wdunwell@uky.edu ; phone 270.365.7541 x 209, fax 270.365.2667, or write P.O.

A reminder!!!! The Cicadas are coming!!!! It is Brood XXIII, 13-year periodical cicada. Doug Johnson, Lee Townsend and Bob McNiel say in Periodical Cicadas in Kentuckyhttp://www.uky.edu/Ag/Entomology/entfacts/trees/ef446.htm

"Insecticides can be used to reduce damage by cicadas but several applications may be needed. Dursban (chlorpyrifos) and Sevin (carbaryl) are labeled specifically for periodical cicada control. Several synthetic pyrethroid insecticides are labeled for landscape trees and shrubs. Often, these insecticides have a repellent effect that causes insects to leave treated surfaces shortly after landing on them. The following examples do not list the periodical cicada but are broad spectrum products that are effective against a wide range of insects - Astro (permethrin), Decathlon 20 WP or Tempo (cyfluthrin), DeltaGard T&O (deltamethrin), and Scimitar (lambda cyhalothrin). Several of these are available only to commercial applicators.
Nurseries under a routine spray schedule should be sprayed according to intensity of the outbreak, which can range from a few cicadas in some areas to massive numbers in other areas. During low level outbreaks application may be needed twice a week. During massive outbreaks, damage will potentially occur even with daily applications. Continued cicada flight to landscapes and nurseries from surrounding woods keeps reinfestation pressure high for several weeks. Control is most effective when the insects are hit directly with spray droplets. Residual control must rely on cicadas sitting on treated surfaces long enough to absorb the insecticide. This can delay or reduce action on the insect." PLEASE READ THE WHOLE PUBLICATION, it is available at your county Extension Office. Another resource for information (in addition to those discussed in the last HortMemo edition
 ) on cicadas is The University of Tennessee publication, SP341-F, Insects: Periodical Cicadas by Frank A. Hale, Henry Williams, and Jaime Yanes Jr.

The Perennial Plant Association 2002 Perennial Plant of the Year is Phlox 'David'.

The authors, the late Hudson T. Hartmann, Dale E. Kester, Fred T. Davies, Jr., and Robert L. Geneve, of Hartman and Kester's Plant Propagation book are obviously all educators. The new 7th edition contains tons of information and the new layout is easier to read. Bob Geneve's Glossary CD-ROM is a wonderful addition. Most of the common forms of propagation are not only defined, but contain a short video segment that shows how the propagation technique is done. I have used the CD as a teaching tool. A great package for the plant propagator.

Dirr's Trees and Shrubs for Warm Climates is a "must have" book on trees and shrubs. For those in Kentucky there are many plants hardy in zone 6 mentioned, indicating Mike may have had to leave a few out of his 1997 Dirr's Hardy Trees and Shrubs. Maybe he should just plan multiple volumes of something like Dirr's Woody Ornamental Plants. I mentioned in a previous HortMemo that he went a little south with the 5th edition of "The Manual", meaning he added a lot of southern plants and now they are in great color images in his latest book. Certain plants like crapemyrtles get a quite thorough treatment. Keeping the Selecting Plants for Specific Characteristics or Purposes section of the "Hardy" book adds greatly to the value of this book. As always, the first thing I check for, is to make sure Dr. Dirr has kept to his pattern of creating great witticisms about plants. He did not let me down, statements such as "fragrance is stinky!" applied to Illicum floridanum, or how about "In the plant introduction business, hyperbole often overshadows reality.", I think we're having fun now. Inclusion of the Kentucky native plant,Rhamnus carolinanus, Carolina Buckthorn, that the late W. D. "Army" Armstrong, UKREC Fruit Specialist, loved and always promoted, brings a warm memory to my heart. Of course, the photo of Mike as a "Tree Hugger" on the back jacket may be worth the price of the book. He and Bob Geneve, A Book of Blue Flowers, have both done their respective University employers proud with the hats in their back cover photos, is this a new protocol for faculty authors?

The invasive plants issue was a topic presented by landscape designers/plantsman that spoke in Kentucky recently. Nurseries and landscapers across the United States are working closely with environmentalists on the invasive plants issue that effects us all. Harlan Hamernik, Bluebird Nursery, Inc., has given me permission to reprint the following: Codes of Conduct for Bluebird Nursery 1. Perform risk assessment for all new species prior to introduction in North America. This will be done using established risk assessment methods or through extensive monitoring on the nursery site. 2. Work with regional experts and stakeholders to determine which species in our region are either currently invasive or will become invasive. Identify plants that could be suitable alternatives in our region. 3. Develop and promote alternative plant material through plant selection and breeding. 4. Phase out existing stocks of invasive species in our region. 5. Follow all laws on importation and quarantine of plant materials across political boundaries. 6. Encourage customers to use, and garden writers to promote, noninvasive plants.

Rick Darke and Cole Burrell gave interesting and thought provoking presentations on landscape design and plant utilization at Garden Gurus IV. Rick Darke's presentation, Winter Garden, had one wishing his book American Woodland Garden from Timber Press was already in our hands, but alas availability is still a few months off. Cole Burrell's presentation, Perennials with Panache, included new and interesting perennial plants, a discussion on invasive plants, and some pleasant wit and humor. Cole's currently working on, Pride of the Prairie: The Evolution of Midwestern Native Landscape Style and the publisher is University of Minnesota Press in Minneapolis. The book, still being written, will be a natural and cultural history of the midwest that will include discussion "on designers like Jens Jensen, as well as ecologists, nurserymen and botanists, all of whom contributed to what we know about the prairie and how we use that knowledge to grow plants, restore and manage prairies and build uniquely Midwestern gardens". Both books sound like "Must Haves" to me. Speaking of books an interesting statement from Rick, verified by Debbie Garman, Timber Press, http://www.timberpress.com is that Dirr's Hardy trees and Shrubs: An Illustrated Encyclopedia is one of Timber Press' best sellers. The book, The Well-Tended Perennial Garden: Planting & Pruning Techniques by 2001 KLI speaker and 2003 Garden Gurus speaker Tracy Disabato-Aust, is also a best seller for Timber Press.

The Kentucky Trees website
provides information on many of the common trees native to Kentucky. The site was specifically developed for K-12 teachers and students, but most gardeners will find it interesting and informative. The site is maintained by the Department of Horticulture at the University of Kentucky and is a collaborative effort between Robert Geneve, Richard Durham, Christy Cassady and Tom Shearin. Partial funding for this site comes from the Kentucky Division of Forestry, Leah W. MacSwords, Director. Visit and enjoy!

Best Wishes for a Happy, Healthy, and Successful 2002.

Win and Christi have had their e-mail addresses changed to wdunwell@uky.edu and cforsyth@uky.edu respectively.


For those that think the study of plants is great fun there is web site at the University of Kentucky Department of Horticulture web site that was created by Bob Geneve, Rick Durham and Christy Cassady that is "worthy" of being considered a fun and interesting site. http://www.uky.edu/Agriculture/Horticulture/virtarbo/welcome.htmcontains some of Bob Geneve's great images and the text contains information about plants not always included in the resources we routinely use. It does require the Authorware web player, but just click on the icon on the opening page to download it. Enjoy!

Mike Cunningham, Greenfield Plant Farm,726 Stephens Road, Hamilton, OH 45011 513.683.5249 wrote in The Buckeye, November 2001, "I have come to the conclusion that I have two viable ways to develop this sense of what (plants) people want. First, and best, is to listen to our customers; which for me means listening to our retail salespeople, who have in turn been listening to our customers. ---- The only other way I see to know what plants people want is to make the time to become more of a gardener myself. Furthermore, to garden with as broad a range of interests as possible, so that my personal preferences begin to approximate that of our customers." Sounds good to me.

If you cannot attend the Garden Guru's hosted by the Purchase Area Master Gardeners, January 12, 2002, in the Cherry Civic Center, Paducah, KY with Rick Darke and C. Colston Burrell please consider the excellent Botanica program on the same day at the Clifton Center, 2117 Payne Street, Louisville. Botanica is hosting a lecture and book signing by Dan Hinkley, Heronswood Nursery http://www.heronswood.com/index.html Dan will be speaking on "The Garden in Winter: Blossom, Foliage, Fruit and Bark". For more information on the Garden Gurus program contact Purchase Area Master Gardener Carolyn Roof, 270.554.4466, e-mail gardener@paducah.comand to learn more about the Botanica Program contact: Mary Anne Thornton 502.896.4251, botanicaKY@aol.com

In the plant category I photographed Pinus densiflora 'Oculis-Draconis', Dragon Eye Pine, at the Southern Region American Conifer Society Chapter tour of Jerry Baker's Baker Arboretum in Bowling Green, KY. I had already seen the plant several times and was introduced again at the ER IPPS meeting in Lexington where Teresa Ford of Yadkin Valley Nursery Co., described it as "A must for variegated plant lovers". I haven't seen it in winter, but Mike Dirr has observed "can be rather attractive,----; unfortunately it discolors to a muddy yellow-brown in winter", that was in Illinois, I will be watching to see how it does in Kentucky because when I observed it in fall it was spectacular.

A reminder for those interested in taking the Kentucky Certified Nurseryman Exam at the Kentucky Landscape Industries Conference and Trade Show, Tuesday, January 8, 2002, information is available on-line at http://www.knla.org/certified.htm

The Kentucky Nursery and Landscape Association booklet Outstanding Plants for Kentucky was created under the leadership and expertise of Kentucky plantsmen: landscape designer Tony Nold; and nurseryman Greg Ammon with encouragement, advice, and the council of the KNLA Board of Directors. This excellent publication lists "worthy" plants known to do well in Kentucky landscapes. The booklet is available at a very reasonable cost and can be purchased in volume by contacting Betsie Taylor, KNLA Exec. Dir., 350 Village Drive, Frankfort, KY 40601 502.848.0055 or 800.735.9791, Fax 502.848.0032 e-mail knla@mis.net homepage http://www.knla.org Those wanting individual copies can get them at a KNLA member retail site.

If you didn't get the info to Hope in time for the Kentucky Grown Landscape Plant Availability Guide you can still get your info posted to the searchable web version by sending a listing of the plants, both common and scientific names, and the size you are currently growing, --- These plants do need to be grown in your nursery within the state of Kentucky, to Hope Crain, Kentucky Department of Agriculture, 502.564.0290 x 253, Kentucky Department of Agriculture, 100 Fair Oaks Lane, 5th Floor, Frankfort, KY 40601. The Guide is posted to the Department of Agriculture web site at http://www.kyagr.com

The West Kentucky Chapter of the KNLA hosted another good education event. This one covered Small Engine maintenance and was held at James Sander's Nursery, Paducah, KY. Special thanks to all at James Sander's Nursery for providing the place, food, and program. For those that missed it recommendations included always using fresh gas, preferable less that 30 days old mixed with 89 octane gasoline. Other tips don't forget to lub the gear box and driveshaft on your string trimmers, most 2 stroke machines are meant to be run at wide open throttle, and for those that use chain saws; safety is very important, and the Kentucky Master Logger Program (contact the UK Cooperative Extension Service in your County) provides excellent training.

Plants: What's happening out there. Well, Sharon Bale told me she learned at the Southern Plant Conference that a dwarf Ironweed (height 2-3 feet), Vernonia lettermannii, is on the market. I am not sure those with pastures will find that of comfort (weed is a part of the name after all), but gardeners that love ironweed will appreciate not having to pinch it back or suffer with a 7-8 foot tall plant. A Google search finds Niche Gardens, http://www.nichegdn.com , will offer the plant in the Fall of 2002. At the ERIPPS Meeting there were several plants mentioned. The most interesting for those in Kentucky is Mike Hayman's selection of Nyssa sylvatica'Hayman's Red', Red Rage™. Nice glossy leaves and great fall color. And here at the UKREC we have Calycanthus floridus x Sinocalycanthus sinensis 'Hartlage Wine' in trial. The proposed name of this cross is Sinoncalycaly raulstonii, don't ya love it! Every time I walk the Buddy Hubbuch Holly Collection at Bernheim Arboretum I look at Ilex opaca 'Chief Paduke' and say I have to have one of those. The tight pyramidal growth habit and interesting foliage are worthy. The fact that this female cultivar, with oblong fruit (a noted characteristic according to Bon Hartline), has a male name has limited it's marketability. It was selected from a plant found in a Paducah cemetery. SiloHouse Nursery, Paducah, KY has started propagating plants from the original plant. Other Kentucky nurseries frequently have a few.

William Bartram's book Travels is available in electronic form at the Documenting the American South site, http://docsouth.unc.edu/nc/bartram/bartram.html an effort by North Carolina University at Chapel Hill Libraries. Cool!

The Louisville Nursery Association meeting at Greenhaven Tree Care was a very nice event. Robert and Patti and their employees have reason to be proud of their facilities and organization. They readily shared how they do business with all attendees. The next meeting will be Wednesday, October 17, 2001 at Bluegrass Farm and Lawn, 800.927.0786 or 502.633.1557, 901 Frankfort Road, Shelbyville.

The Eastern Region International Plant propagator's meeting was a great success thanks to all involved but much of the credit should go to Chairman Dr. Bob McNiel. I will talk plants next month but for those in the retail part of the nursery/landscape industry Wallitsch's Garden Center, Louisville, and Wilson's Nursery and Garden Center, Frankfort, that were on the ERIPPS tours are worth a visit. And if you missed the Eastern Region American Conifer Society meeting you can add Leichhardt Landscaping and Garden Center to your list of places for a future visit. Casey and Cindi Schott have made dramatic changes since taking over the Nashville Road garden center just a month ago.

Allan M. Armitages new book Armitage's Manual of Annuals, Biennials and Half-Hardy Perennials, 2001, Timber Press, Inc. ( http://www.timberpress.com ) when added to his Herbaceous Perennial Plants and Michael Dirr's Manual of Woody Landscape Plants pretty well rounds out the resources needed for the average nursery/landscape business or educator. Set up in the same fashion as his Herbaceous Perennial Plants (2nd edition, 1997) there is a wealth of information available. Well, yes, a grasses book would seem to be needed but actually Dr. Armitage has included a few grasses (the non-hardy Pennisetums) in this book, as he included perennial grasses in his perennials book. Read the introduction at least once to know how he defined the plants that occur in this book. Depending on where you live you might find yourself going back and forth between the perennials book and this one.

I will see you all at the Kentucky Nursery and Landscape Association Summer Outing at Bernheim Arboretum, Clermont, KY on September 6, 2001. From there we will all be at the Eastern Region International Plant Propagator's Society meeting in Lexington, KY, September 30-October 3, 2001. See HortMemo 6, below, and/or the upcoming meetings list. A great opportunity to attend an IPPS meeting right here in Kentucky.

Diseases of Woody Ornamentals and Trees in Nurseries, 2001, edited by Ronald K. Jones and D. Michael Benson, APS Press, The American Phytopathological Society, St. Paul, MN 55121-2097 is an excellent resource for those in nursery production enterprises. In addition to discussion of diseases specific to plant genus there is a section, disease management, which includes: horticulture practices to reduce disease development, tissue culture, and disease management for nurseries using recycling irrigation systems to mention a few of the 16 chapters in this section. The book can be ordered online at http://www.shopapspress.org/disofwoodora.html or by calling to APS Press 1.800.328.7560

I visited the J.C. Raulston Arboretum in July and saw the building of the Ruby C. McSwain Education Center was progressing. While wandering the arboretum I came across a J.C. quote that many may know but seems "worthy" of repeating: "Plan and plant for a better world." I like that! With that in mind, the University of Kentucky Arboretum is also in the process of getting it's visitor center and office built. There is a fence across the entrance path, but as of last week workers had put down some attractive pavers to cover the detour walk to the demonstration garden via the Rose Garden path.

The Pennsylvania Horticulture Society (PHS) has announced the 2002 PHS Gold Medal Plant Awards (formerly known as the Styer Award of Garden Merit, some people still use this title in articles and catalogs). The winners are Buxus sempervirens 'Vadar Valley', Campsis grandiflora 'Morning Calm', Malus 'Adirondack', and Physocarpus opulifolius 'Diablo' Diablo™. Previous winners and information about the program can be found at http://www.libertynet.org/phs/gold/gold1.html 'Vadar Valley' boxwood and 'Morning Calm' trumpetcreeper have done alright in the UKREC landscape, but have yet to be severely tested by one of "those Winters". 'Adirondack' crabapple is an introduction of the late Dr. Egolf, U. S. National Arboretum, known for it's resistance to several crabapple diseases. The Diablo ninebark is rated as a zone 2-7 plant and should survive our area's Winters, but Mike Dirr questions it's ability to hold the purple foliage color in heat and humidity in a series of fun comments on the cultivar on p. 713 of the 1998 edition of the "Manual".

Bernheim Arboretum has started adding beds to the area immediately inside the entrance gates on the left side of the road. You might start watching this area to see young plants as they grow and develop their mature character. The constant expansion of Bernheim's collections is making my goal to see every plant in the horticultural collections "show it's stuff" (most obvious ornamental characteristic) more difficult. Touring with others is very advantageous. Recently, members of the Theodore Klein Plant Award Committee walked the Sun and Shade Garden and a Clerodendron was pointed out to me that I have probably walked past numerous times without noticing. Speaking of Arboretums, I hope everyone has been watching the development of the new rose beds and other activities going on at the University of Kentucky Arboretum, Lexington, KY. The huge piles of soil have been shaped and planting continues there also. What a blessing to have these great public gardens in Kentucky.

I was embarrassed to have Dr. Bob McNiel stop by and find that the pot-in-pot plants in our beds had rooted into the soil below the socket pot. We had not used any chemical root control and were lifting the pots to break any roots trying to get into the soil under the socket pot. It turns out the roots had circled and it wasn't until one tried to actually remove the growing container completely from the socket pot that we found the roots had gotten into the soil. It took some real work to get the roots severed. Pot-in-pot is a great system but once roots enter the soil harvest and possibly transplant success can be negatively impacted. Remember, lift and turn the growing container.

The KNLA Summer Outing will be at Bernheim Arboretum, Clermont, KY http://www.bernheim.org . In addition to tours of the Arboretum and a trade show, Dr. David Creech, Professor of Horticulture at Stephen F. Austin State University, will be speaking. Part of his fame is his service as director of the ten acre SFASU Mast Arboretum, http://www.sfasu.edu/ag/arboretum/index.htm . Dr. Dave Creech is a well-known entertaining horticulture speaker, see you there.

The Eastern Region International Plant Propagator's Society meeting will be in Lexington, KY, September 30-October 3, 2001. In addition to some great tours of private gardens, public gardens, Bernheim Arboretum, Rosehill Greenhouses, Throughbred Daylilies, F.W. Rickards Seeds, Gainesway Horse Farm and Arboretum, Wallitsch production greenhouses, Wilson's Nurseries (if you get a chance stop by Charlie's new garden center complex, Frankfort, KY), and more. There is a excellent propagation and plant program and roundtable discussions. In addition, there will be a poster display of research projects, plant auctions, and numerous other things to attract the plant propagator/plants person. Of course, the objective to "Seek and Share" propagation information is the goal IPPS, but there is the opportunity to increase one's industry network, always an added benefit. See Upcoming Meetings for more info.

I added the following to my Getting Started in the Nursery/Landscape Industry discussion following an e-mail from Dick Bir telling of Ted Bilderback's great article: Nutrient management and monitoring is important to getting maximum growth with minimum loss to the environment. Loss to the environment is also an economic loss, so monitoring to avoid loss and at the same time provide adequate nutrient for the plants is a "win, win" situation (I like that). The "Virginia Tech PourThru Technique" originally described by Dr. Robert Wright (a brief by him on lysimeter use in the nursery is at the Soil Moisture Site) was based on monitoring the amount of soluble salts leaching out the bottom of the container following an irrigation event. A recent publication on the topic, Using the PourThru Procedure for Checking EC and pH for Nursery Crops, http://www.ces.ncsu.edu/depts/hort/hil/hil-401.html has been prepared by Dr. Ted Bilderback of NCSU. With the advent of pot-in-pot production systems the lifting of the pots and elevating them so leachate can be collected from the bottom of the pot is not practical so lysimeters (Soil Moisture, Inc, http://www.soilmoisture.com/horticulture.htm ) are used to collect soil water into a tube so water can be extracted with syringe for soluble salt measurement. This technique will probably be called the Virginia Tech Extraction Method.

In The Newsletter of the Garden Conservancy, 12 (2), Spring 2001, there was an excellent article by Richard W. Lightly, past Director of Mt. Cuba Center for the Study of Piedmont Flora, on Mt. Cuba Center founder Pamela Cunningham Copeland. Mrs. Copeland died in January 2001. I had the good fortune to visit Mt. Cuba twice on UK Hort Club Spring tours and found the place to be fantastic. I was always surprised that considering all the talent at Mt. Cuba, Richard Lightly worked at Longwood Garden before Mt. Cuba and has a fantastic garden of his own and current Director Rick Lewandowski was at Morris Arboretum for many years, Mrs. Copeland did much of the design herself. Wandering the garden I noted a mailbox in the garden. Curiosity got the best of me and I looked in the mailbox near the gazebo/pond once, it was filled with flags and surveyors tape to be used to mark out changes in the garden, ie removals and where new plants were to go. There was a wildflower guidebook in the one I looked in, that made me feel better as I always need to use my book resources to get information on plants, maybe Mrs. Copeland did also. Mrs. Copeland's garden is "Worthy" and if you ever get the opportunity to visit Mt. Cuba, please do!

The winter has surprised us. Not in any way severe by pure low temperature standards, but there was significant damage just the same. We started seeing samples of azaleas and boxwood early, even in the fall. The bark had been frozen and mechanically forced off the stems leaving bare wood showing and a plant dead to the ground. We have seen injury on maples, including a Acer palamatum 'Bloodgood' in the UKREC landscape that made us become concerned about a possible disease problem, none was found. Indigofera kirilowii is frequently killed to the ground, but this year one in my yard is in full flower with leaves expanding and the one at the UKREC is dead.

After making mention of "organic nurseries" in HortMemo 1 (January 2001) I came to the conclusion "organic" is in the "eye of the beholder" and will require some further definition. Few nurseries are totally organic, but many have some organic production practices. To say one is fully organic may require some proof. NMPro's e-mail newsletter (to sign up for this free newsletter go to http://www.greenbeam.com/email/email-form.html ) contained a statement indicating that Maryland has an nursery organic certification program. I spoke with Valerie Francis in MD and learned that they were applying their Organic Certification Program to any agricultural enterprise that fulfilled the criteria. Well, well, time to e-mail Hope Crain, KY Dept. of Ag. Organic Certification Coordinator. In her reply she said, "The Certified Organic Program in KY has been set up primarily for fruit and vegetable growers and is now getting into livestock more heavily. There are regulations for the growers, as well as processors and handlers. However, if there was a nursery interested in certifying their operation as "organic" and can follow the regulation as a grower/producer, the Department would work with that grower to do so. Currently, the certification fee is $10 no matter the size, location within the state, or dollar amount sold by the nursery. Applications can be received any time but the inspection must be done during the growing season. In August of 2002, under the USDA federal organic standards, anyone representing their product as organic must comply with the federal standards. Only the growers, processors and handlers with less than $5,000 annual sales are exempt from certification, however, they must also comply with the regulations in order to use the term 'organic'. As a federal guideline, this will cover every state as well as every commodity USDA reviews. --. I believe both greenhouses and nurseries can be certified under this federal law. If you have other questions please feel free to call or e-mail them and I'd be happy to help if I can. Thanks for the interest! Hope".

Suction-cup lysimeters are used for monitoring soluble salts in pot-in-pot systems. I had the pleasure of hearing Dr. Robert Wright, originator of the Virginia Tech Liquid Fertilizer System for Container Grown Plants that established the pour-through technique of nutrient monitoring for container production, at the recent American Society for Horticultural Science Southern Region meeting, talk on using suction-cup lysimeters in pot-in-pot systems. A Suction-cup Lysimeter, is a tube with a porous tip, that is placed in the growing container in the pot-in-pot system. Using a hand vacuum pump water in the media is pulled through the ½ bar porous tip into the tube where it can be extracted with a tube and syringe, then tested for soluble salts. This is a modification of the VTECH "pour-through" method used on above-ground containers so that the water can be extracted without having to lift large-heavy containers with a plant from the socket pot and place it on a elevated surface in order to pour-through water and collect the leachate for a soluble salts reading. On-line information on lysimeters is available from http://www.soilmoisture.com and a research paper on lysimeter use by Ron Walden and Alex Neimeira was presented at the 1997 SNA Research Conference is available in Proceedings 42:165-167, or the SNA web sitehttp://www.sna.org/research/97proceedings/Section0246.html

I was asked at the Kentucky Landscape Industries Winter Conference if there are any organic nurseries, I replied I didn't know of anyone promoting that they were an organic nursery. Then George Kozairz, a marketing and financial consultant, stated he felt the environmental factors were important to the future marketing of nursery products. To produce and promote nursery products as an "environmentally friendly" product grown using "environmentally friendly" practices has long been a goal of Extension programs and lead to the use of IPM and BMP principles. I had not really thought about organic nursery production til this question was raised and I heard Tony Avent say his nursery, Plant Delights, was "producing plants organically". So let's start some dialog, see you at the BMP workshop.

James Sanders, founder of James Sanders Nursery, Paducah, KY passed away December 2, 2000. Over the years he shared many stories from the early years. He was blessed with good health for most of his 88 years and was frequently at the nursery and most gardeners and industry people in west Kentucky knew him and enjoyed his counsel. There is a 'Sanders' holly that now resides next to his house that I believe he and his brothers collected in TN back in the days when holiday decorations and grave blankets used a lot of green foliage and holly branches with large red fruit were the most popular. His nursery has been a leader in the area for many years and numerous Sanders' family members work in areas of ornamental landscape horticulture today.

Clarence "Buddy" Hubbuch died Saturday, November 4, 2000. I will miss Buddy with his great shock of white hair, vigorous lifestyle, and gentle sharing nature. He had a special way of speaking that I can hear in my mind when I think of him, a gift I appreciate having. I promised Buddy that I, and I was sure the legions of people that hold him in a special place of honor, would keep his memory alive by telling students and plants people of his great contributions in the form of the collections he started at Bernheim Arboretum and his great enthusiasm for plants, please help me keep that promise.

Whoops! I made an error with the nomenclature of Viburnum 'Eskimo" in the last HortMemo. Ruth Dix, of the National Arboretum, pointed out that Viburnum 'Eskimo' is described at the National Arboretum site, http://www.ars-grin.gov/na/newintro/eskimo.html Ruth wrote "Viburnum 'Eskimo' was a complicated cross and the species was not to be listed as part of it's name".

Last issue I mentioned the KNLA Summer Outing at Bernheim Arboretum on September 7, 2000. I, also, introduced Fred Spicer, Landscape Architect and guest speaker. What I failed to mention was that Dr. Paul Cappiello of Bernheim Arboretum provided the biographical sketch on Fred Spicer I used to prepare that announcement. I also failed to mention that Paul will be giving a presentation on Great New Plants and Their Sources. As Paul speaks first just save that seat I requested in the last issue for his talk and I will try to hang on to it til Fred finishes his presentation on American Garden Awards.

The Pennsylvania Horticulture Society (PHS) has announced the PHS Gold Medal Award (The Styer Award of Garden Merit) winning plants for 2001 ( http://www.libertynet.org/phs/gold/gold1.html ). The three they selected are Cornus mas 'Golden Glory', Hydrangea arborescens 'Annabelle' , and Ilex opaca. These are all great plants Kentucky's Theodore Klein Plant Award (TKPA) Committee has considered as candidates for the TKPA and the committee even selected the Ilex opacacultivar 'Judy Evans' as a winner for 1999. For more info.  

Recently while on a nursery visit with Dr. Bob McNiel we noted what appeared to be herbicide damage on birches. The damage looked like a reversed Clomazone (Command) injury. The veins and areas immediately around them were white with the rest of the leaf (outer portion) green. The weeds in the area showed a similar injury with some leaves, especially on Bermuda grass, being completely white, even cloudy. In talking with the nurseryman we believe the culprit was Norflurazon (Predict or Zorial). At this moment we are not sure if the damage is rate dependent or not, but it does bring up the difficulty when we deal with so many plants and a plant genus or species is not to be found on the herbicide label. Birch was not on the label, but other plants in the nursery were not damaged that were not on the label either, and one plant that was damaged appeared to be a rate related problem at the end of a row. What to do? Always read the label and when a plant is not on the label realize you are taking a risk that could lead to loss of a seasons growth or even loss of the plant(s). Statements, such as occurs on the Predict label, "To avoid plant injury - do not apply until the fall following the first full season of field growth after transplanting.", can often determine a successful herbicide application versus a plant damaging one. Dr. Bob McNiel presented a good discussion on weed control in an article in KNLA Nursery Views, 1999, vol 29(4):10.  You can e-mail me at wdunwell@ca.uky.edu or call Christi 270.365.7541 x 221 to have a hard copy sent to you.

The KNLA Summer Outing is at Bernheim Arboretum, September 7, 2000, with Fred Spicer speaking on Landscape Design and Installation. Fred is a registered landscape architect and first-rate plantsman. He is a certifiable plant zealot! He manages all horticulture for the two arboreta operated by the Morris County Parks Commission. Frelinghuysen Arboretum and Willowwood have developed first-rate plant collections and contain some wonderful old specimens as well. He is heavily involved with NJ's counter-part program to our Theodore Klein Plant Award. He has for the last several years, coordinated the American Garden Awards; a program sponsored by ANLA. The program makes awards to superior design/build projects across the country. His presentation is sure to be standing room only, save a seat up front for me!

An interesting web site that was shared with ASHS Nursery Crops Working Group during the Nutrient Management Planning for Container Nurseries workshop was Surf Your Watershed (locate your watershed) at http://www.epa.gov/surf3/locate . You put in your zip code and it locates the watersheds nearest you and tells you about them; the quality of the water and the watersheds vulnerability to damage. Kentucky Lake is considered better quality and low vulnerability to pollution while the Lower Cumberland (Lake Barkley) is also better quality but is vulnerable to pollution damage.

Bernheim Arboretum has introduced Fothergilla major 'Red Licorice" to the nursery industry. The plant is described as having flowers with a licorice fragrance and a great red fall color even in partial shade.

Our plan is to have at least 10 years and 5,000 pages of the past proceedings in this system by year's end. We think this will be a valuable tool for everyone in the industry and we have plans to keep it open to everyone." I have tried it and it is a valuable resource.

In the "IT'S A SMALL WORLD" department. While in England visiting the Hampton Court gardens and walking with Bob McNiel and my wife, Stephanie, I saw a woman that looked like Gisele Martin, a Master's degree alum from our program. Sure enough it was her, she was there touring with University of Florida students and faculty. Incredible, the odds of us being in the same place at the same time and actually seeing each other in the large park-like gardens or in the Castle of Hampton Court are astronomical. Other people from UK didn't see her. Continuing the "it's a small world" department. I met Anne Amerongen again, this time at Monet's Garden in Giverney, France. Anne is a North Carolina State Univ. Cooperative Extension Master Gardener I originally met while attending the Plant Master Program, advanced training for Master Gardeners, at the Hanover Arboretum, Wilmington, NC, then met later at Tony Avent's Plant Delights Nursery near Raleigh, NC. At Giverney, Anne asked me what a plant was, I told her and her friend, and walked off without recognizing her. Thankfully, she said hello, we shared a laugh and a few stories of our travels before going our separate ways. Incredible!!!! Cindi Finneseth claims my meeting people I know at remote places has used all my luck and without that luck I can never win the lottery.

Next month is one of the "biggie" issues (Jun. & Dec.) for those that get this via postal mailing. Please send in any meeting announcements not listed on the web site so they can be included in June edition.

UKREC All-Commodity Field Day will include Ornamental and Fruit research and demonstration plots. July 20, 2000. UK Research and Education Center, Princeton, KY.

Dr. Bob McNiel lead a group of students, faculty, and Master Gardeners on a "Great Adventure" to Europe in May. As always we saw many things related to the nursery and landscape industry we haven't seen before. We also learned that many of the new cultivars of ornamental plants are being developed in Kentucky and the good ole U.S.A. While in Germany we saw Richard Fiest's Itea 'Little Henry" in production through an agreement with Spring Meadow Nursery. The proprietor of that nursery said the Americans are very aggressive about the development of new cultivars and he, like many others we visited, buys liners from several U.S.A. nurseries.

The German nurseries we visited promote the idea that "if you take something from nature you must give something back". This thought lead to some very interesting developments one was a huge roofed building (60 x 80 meters) with a "living roof".

Evaluating plants seen in Europe can be deceiving. Many plants growing there we don't see in Kentucky. In spite of the more northern latitude the climatic zones for the countries we visited match USDA zones 7 and 8. I had to avoid getting too excited about plants that looked great but wouldn't survive our winter cold or summer heat.

Several of the Euphobias I recently photographed in Mitch Liechhardt's Garden I saw in almost every major European Garden we visited. The most common was Euphorbia griffithi 'Fire Glow'.

Epimedium x versicolor 'Sulphureum', Theodore Klein Plant Award winner for 2001, was frequently encountered as a ground cover and was in bloom most places we visited including gardens some of us visited in Louisville before leaving for Europe.

We visited two big tree nurseries, both had been around for four generations. A multigenerational company has it's advantages. Some of the trees were grown on 50 year cycles which included transplanting every five years. We were impressed that some street and parking lot trees are limbed up to 4 meters (13') because they are planted very close to the roadways and adequate clearance is needed for trucks and tourist coaches. They also trained two container plants into 10'+ wide arches. I could not picture in my mind how they were shipped.

The University of Kentucky Arboretum officially became the state botanical garden of Kentucky March 21, 2000 when Governor Paul Patton signed Senate Bill 190.

Theodore Klein's Yew Dell Farms which includes the 33 acres of arboretum with the castle and homesite is in jeopardy of being broken up through a sale necessary to settle the estate. Friends of Yew Dell and the Oldham County Historical Society have raised enough money, through their "Jewel Worth Preserving" campaign, to put a deposit on the property. They still need to raise more than a million dollars to complete the purchase and make immediate repairs. Paul Clinton, leader of the quickly organized Friends of Yew Dell, can be reached at 502.241.0471 for more information or you can write to the Friends of Yew Dell, C/O Oldham County Historical Society (502.222.0826), 106 N.

In an official ceremony, Saturday, April 22, 2000, Bernheim Arboretum and Research Forest dedicated the Holly Collection in honor of Buddy Hubbuch, retired staff member, and Horticulturist. A bronze plaque was placed at the site naming the collection 'The Clarence E. "Buddy" Hubbuch, Jr. Holly Collection'. Buddy also received a plaque for his home. LaDonna Eastman of Bernheim sent with a great picture the following text prepared by Paul Cappiello as part of the press release related to this great event: Buddy Hubbuch came to Bernheim on December 27, 1962 with instructions to "create" the Arboretum… and create he did. During his tenure, he introduced, tested, propagated and grew over 2,000 varieties of trees and shrubs he was familiar with and ones he wanted to learn more about. His legacy includes the renowned Holly Collection. At the present time, the collection contains over 700 specimens representing more than 350 individual taxa from all across the Northern Hemisphere. Twenty-two new varieties were added to the collection in 1999. If you want to write to congratulate Buddy, his address is chubbuch@webtv.net or 5103 Woodhill, Louisville, KY 40219

I read in Botanica's March newsletter that Mike Hayman, well-known Louisville plantsman, founder of the Seneca Gardens Arboretum (I understand he has expanded the concept to other sites), Louisville Courier Journal photographer and general all-around good guy won the Fred Wiche/Operation Brightside Award for his outstanding contribution to public horticulture in the Louisville area. I am pleased that Mike won this well-deserved award, but my first reason for mentioning him in this newsletter was to mention that he has selected an excellent Nyssa sylvatica cultivar. It is under development right now so talk to him if you are interested growing this interesting selection.

Speaking of Botanica I will have the pleasure of giving a presentation "Another Great Adventure - UK Horticulturists Traveling in China, Part 1" on April 18, 2000, 7:30 pm EDT at Commonwealth Bank, 286 North Hubbards Lane, Louisville KY.

The Louisville Nursery Association will have their first meeting of the season March 15, 2000 starting at 6:00 pm. Louisville Tractor Company, 1675 Watterson Trail, Louisville, KY 40299 is the host for this meeting. LNA has established a Wilford Day Education Fund honoring the great LNA supporter Wilford Day who died prematurely in January. If you knew no one else in LNA except Wilford you knew you always had a friend at the LNA meetings because he was ALWAYS there and every new member knew Wilford by the end of their first meeting.

If you are on your way to the LNA meeting be sure and stop off at Bernheim. The Hamamelis collection is in bloom. The plants are small but all the H. x intermediacultivars are in bloom providing a opportunity to evaluate the different cultivars. One cultivar named for the late James Wells, mentioned in the last edition, has very dense showy yellow flowers, but I didn't have time to do the fragrance rating (Paul Cappiello is rating fragrance on a 1-5 scale). If you stop by let me (& Paul) know what you think.

Bruce Briggs, the great plant propagator, well-known for tissue culturing many otherwise hard-to-propagate desirable ornamental plants passed away February 4, 2000. Bruce died in his sleep. I took my last photo of Bruce as he was taking a photo at the ER IPPS meeting this September. I never thought I wouldn't have the opportunity to get a better picture at a later date. His contribution to the nursery industry will be long remembered, as will the great plants he introduced to the industry.

James S. Wells, the internationally known plant propagator, died on January 5, 2000. I met Mr. Wells through his book Plant Propagation Practices that was used by Dr. Harvey Gray to teach me plant propagation at the SUNY at Farmingdale in 1967. I still have that book in my office today. By the time I had met Dr. Gray and Mr. Wells in person they had mellowed somewhat, but my first boss, Richard Carter, Evergreen Nursery and Carter Landscaping, East Quogue, NY, remembers loud vocal debates between these two on the how-to and whys of plant propagation at International Plant Propagator's and New York Nurserymen's meetings. James Wells leaves a great legacy of knowledge to all of us, he will be missed.

The Kentucky Nursery and Landscape Association (KNLA) began in 1926 and has a current membership in excess of 300 nursery/landscape/garden center firms. The letter introducing the organization to prospective members states "Our primary goal as a network of professional nursery growers, landscapers, garden centers and others interested in horticulture, is to provide educational opportunities to members ----". Many of you are aware of the fantastic summer outing that was held at Bernheim in September. Another great opportunity for industry networking and learning will be offered January 11-13, 2000.

I have had the good fortune to travel quite a bit this year. On my way to Quito, Ecuador in early October I was held in Miami because the eruption of the Guagua Pichincha volcano closed the Quito airport. I decided to take advantage of the situation and visit the Fairchild Tropical Garden. I enjoyed the opportunity to meet with Buddy Hubbuch's son, Chuck Hubbuch, Director of Collections. Dr. Monte Johnson, UK Entomologist, and I got the grand tour. You may wonder why would I care about tropical plants, well, they continue to provide additions to the annual plants we use in the landscape.

What did I learn while in Ecuador? Well, for starters there is no better way to control diseases than to not have them. Sanitation in a year-round growing environment is very difficult. While we preach, start out with the best plant possible, put it into a pest free soil or media, water it with clean disinfected water of the appropriate pH when necessary, monitor your fertilization with soil, leachate, or leaf samples, eliminate stress, and treat for pests with the proper pesticide for an identified pest problem, it isn't always easy. Sometimes we must make significant changes to accomplish these goals and to finish a quality-pest-free crop.

We visited several in-the-field cut-flower operations. One grower used a vacuum, D-Vac, typically used in sampling for pests, to remove leaf miners from his 30 acres of Aster cut flower growing beds. He had a predator in the field to help control the leaf miners and he had developed a special container for the vacuum that had screens that would let the predators escape but keep the leaf miners in the container. Great stuff! I assume we will see more and more of these type of techniques to control insect pests.

The KNLA Summer Outing at Bernheim Forest was very well received by the 300 plus people that attended and participated. KNLA Board members and planner for the event Rudy Voltz, Paul Kaelin and Pat Dwyer provided a first class educational event with presentations by Bill Thomas and Dick Ammon. The trade show and equipment demonstrations were excellent and all who attended wanted more time to tour the plant collections with the outstanding Bernheim staff that was present. Special thanks to Paul Cappiello of Bernhiem and KNLA President Charlie Wilson for enthusiastically supporting the committee, which by the way, held a critique of the event immediately after it ended to ensure good ideas to make this event even better next year were not forgotten. Considering the turnout and the interest in the collections it would seem we can remove the word "hidden" from the late J. C. Raulston's comment describing Bernheim as "the hidden jewel of the botanic world".

IT IS BOTANICA! I let the spell checker take the "a" off Botanica in the last issue. You might be asking what is Botanica? It is a Louisville-based non-profit organization with gardeners and nursery/landscape industry representatives as members. The primary interest of the group is in gardening activities and the joy that gardening and plants bring to peoples lives. Gardening is seen as a community of people by this organization. The city of Louisville is blessed to be thought of as a "gardening mecca" (my term) thanks to a long tradition of great nurserymen and landscape designers combined with the relatively recent efforts of Botanica. I remember the first time I met Mary Anne Thornton, the person who started it all, at an LNA meeting and she asked me about her idea to start a gardening organization. She said she had already been involved in different gardening organizations and saw a need for a organization to bring all the societies and industry organizations together. I told her it sounded like a great idea. That was a number of years and 8 great seminars ago. I recently called her to get information on Botanica for this issue of HortMemo and she told me to not forget The Fall Gardening Conference, October 2, 1999, with Roy Lancaster (See Upcoming Meetings below). Very typical of her dedication to Botanica and the gardening community of Louisville, Kentucky, and the world.

Lest we forget where we started, I read this Confusius statement while in China. "A craftsman, if he means to do good work, must first sharpen his tools". This statement brought a rush of pleasant memories of the daily knife, spade and pruner sharpening during my early years in the landscape industry. The statement applies to all things we do. It is good to preplan and be prepared for any task or job, whether, actually sharpening a tool, developing a nursery planting, diagnosing plant problems, or doing a landscape design or construction job.

The daylilies have been fabulous this year. We have John Rice's daylilies, Thoroughbred Daylilies, Paris, Kentucky, 606.988.9253, in our trials this year. My favorite of John's as a first year bloomer is NANCY LIGON, the edge and edge color are great, but there are several others that are large, well edged and unique colors, including, wow! CROWN OF CREATION.

We have been looking at Joe Swanson's, Swanson's Daylilies, Lexington, KY, 606.272.2791, the last few years. The big loud MILANO VIOLET MARK, MILANO ROCKET, and MILANO MARASCHINO are great. MILANO MARASCHINO is a favorite and has really done well as a landscape size clump. I also, like, OCTAVIAN CHERRY DOLL and the funky little, lavendar with a white line down the center of the petals and off-white sepals, OCTAVIAN MARBLE MODEL.

We don't want to forget the people that got us started, Casey and Cindy Schott, Schott Gardens, 270.781.0254. Their SUNFLARE is a landscape winner. JANICE WENDELL has done well at the UKREC and at home. A very special photograph of a daylily is one taken of the Schott's NEDDIE DOWNING.

With our daughter named Lisa, having the petite LISA MY JOY blooming always pleases my wife and I. Stop by the UKREC, observe the daylilies and vote for your favorite by leaving a note with the receptionist in the UKREC lobby.

I learned of the Garden Conservancy because, container gardener and author, Ellise Felton, sent me a copy of their 1997 Open Days Directory to use to attend the Open Days (special days that select private and public gardens in an area are open to the public, I have visited several gardens that would never be open to the public if not for this program) and as a resource to find special gardens to visit while on sabbatical. The Garden Conservancy was formed in 1989 to preserve gardens by facilitating their transition from private to independent nonprofit ownership and operation. The Conservancy serves the public's growing interest in gardens by providing access to the finest examples of the art of gardening in America and by offering educational programs that further this art. The Conservancy is also a resource for individuals and community groups in need of legal, fund-raising, and management assistance to further their own garden preservation projects. The 1999 Open Days Directory has more than twice the listings the 1997 one had. Contact: The Garden Conservancy, P.O. Box 219, Cold Spring, NY 10516, 914.265.2029 e-mail: Gardencons@aol.com

I have been in China for the last 3 weeks and enjoyed another "great adventure". Drs. Bob McNiel and Tom Nieman were our fearless leaders. Sixteen students and four faculty toured northern, central, southern and eastern China. Visiting China Universities we learned about many of the crops of China, in particular greenhouse vegetable, flower and mushroom production, but also, gingko for tea, silk worms, wheat, rice and other crops. We visited several ornamental enterprises including the Dounan Flower Market. The Dounan Flower Market, near Kunming, is planning to open a flower auction in the near future. While we were visiting the market, another group from Europe was also there investigating the market. The nearby International Horticultural Expo was a highlight of our tour. The Chinese gardens at the Expo were fantastic, but they didn't compare to actually visiting many of the old gardens of Suzhou. We saw a rapidly developing country, with more construction going on than anywhere I have ever visited. In horticulture there is a move to profitable exporting of vegetables and flowers. While the standards of quality were not up to U.S. market standards, the growers were well aware of it and had plans to meet those standards.

The Boone County Arboretum was dedicated May 2, 1999 and has one of the best maps I have seen for a large planting of trees. The Boone County Arboretum was designed by Dick Ammon. I learned of it while preparing my Plant Study Sites file for my home page. I hadn't added the Boone County Arboretum because I didn't know much about it, but Dr. Mike Klahr, Horticultural Extension Agent for Boone County sent the needed information and map. The Arboretum is in Central Park and currently encompasses 125 acres and has 700 trees planted and labeled. The introduction states "Future plans include the addition of 500 ornamental shrubs". For more information contact: Mike Klahr at 606.586.6101 or the Boone Co. Parks Office 606.334.2117.

I wrote about the The Associated Landscape Contractors of America (ALCA) a few months ago when they hosted the 1999 ALCA Student Career Days in Lexington. I was very impressed by that event and thought this month ALCA, established in 1963, would be the organization highlighted. "The Associated Landscape Contractors of America is a trade association which promotes business management skills and the profitability of its (2000+) members' businesses. ALCA provides its members with a good business foundation to help them evaluate, plan and better manage their businesses. Member firms have direct access to marketing tools, industry specific business publications and business experts who can assist companies in becoming more profitable." You can get more information by contacting ALCA by writing or calling 150 Elden Street, Suite 270, Herndon, Virginia 20170 phone: (703) 736-9666; 1-800-395-ALCA fax: (703) 736-9668 homepage: http://www.alca.org/

The John Bartram Association is celebrating the 300th birthday of John Bartram. Numerous activities have been planned including: a survey of all Frankliniana altamahagrowing; hosting the Bartram Commemorative Stamp Dedication, May 18th the day before the start of the Bartram 300: A Gathering, Symposium, May 19-21, and the Bartram 300 Living History Festival, May 22-23, 1999. For more information on the May 19-21, 1999 symposium you can contact Historic Bartram's Garden, 54th Street and Lindbergh Blvd., Philadelphia, PA 19143, 215.729.5281, Fax 215.729.1047 or check out their homepage http://www.libertynet.org/bartram . The US Postal Service will release stamps on: William and John Bartram, American Botanists, with artwork that looks like William Bartram's famous botanical drawing of Frankliniana; Stamps of Tropical Flowers; and, a stamp as a collage with an image of Frederick Law Olmsted and obvious icons of a couple of his gardens. Release dates are tentatively set as May 18th for Bartram and Tropical Flowers and sometime in September for Frederick Law Olmsted stamps. You can check with your local U.S. Post Office or call 1.800.STAMPS24. All these stamps seem ideal to go on the first class mail of an ornamental horticulturist.

I cannot put in all the organizational meetings that occur every year in the ornamental horticulture arena in Hort Memo's upcoming meetings list. So I thought I might help you build a mailing list of organizations that interest you by highlighting some of the organizations I come across in my mail and e-mail. The American Horticulture Society's mission is "to encourage and recognize excellence in gardening-by advancing the art, science, and enjoyment of horticulture, and by educating and inspiring people of all ages to become successful, environmentally responsible gardeners." AHS publishes a magazine The American Gardener and maintains offices at the River Farm, 7931 East Boulevard Drive, Alexandria, VA 22308-1300. The River Farm is a Botanic Garden worth visiting, especially if you are on your way to Mount Vernon, just down the street. They have theme gardens, and some interesting trees such as a giant Osage Orange. They also host annual meetings, the next one is to be held in Boston, MA June 10-12, 1999. You can find schedules of the their meetings and other activities on their homepage at http://www.ahs.org .

1250 people attended the Associated Landscape Contractors of America Student Career Days in Lexington. Dr. Bob McNiel received a standing ovation at the awards ceremony in recognition of his organizing this very impressive event. I was told the limiting factor to growth of a landscape contracting company is attracting qualified personnel. That explains the long hours and expense the 80 plus landscape companies expended trying to attract the students to intern or work for their firm. Competitive salaries helped companies succeed in their quest.

The West Kentucky Chapter of the Kentucky Nursery and Landscape Association held it's 1st meeting at Rob Stanfa's Rolling Hills Nursery in Murray, February 25, 1999. There was a good turnout and officers of the KNLA and the WKY Chapter discussed future plans. Hope Crain of the Ky. Dept. of Agriculture talked about the new Kentucky Grown Landscape Plant Availability Guide. Amy Fulcher discussed the Invasive Species Executive Order. It was a great meeting and more are planned.

Last month I mentioned the book Urban Trees: Site Assessment, Selection for Stress Tolerance, Planting I got off the web(http://www.cals.cornell.edu/dept/flori/uhi/urbantrees.pdf ). Eddie Atherton, Owensboro City Forester, called to say he had called author Nina Bassuk at Cornell University and a hardcopy of the publication can be purchased. He stated he had received his copy and it was "well worth the $8.00". To order a hardcopy send an $8.00 check, made out to Cornell University, to: Dept. of Floriculture and Ornamental Horticulture, Attn: Kelly Woodhouse, 20 Plant Science Building, Ithaca, NY 14853.

I received the 1999 OSU Extension Agents' Handbook of Insect, Plant Disease and Weed Control, E-832. The huge resource covers all agricultural commodities including animals, agronomic crops, household pest control and horticultural crops. On page 1 it says "Copies of the Extension Agents' Handbook may be ordered at a cost of $25.00 from University Mailing Services, Publishing and Printing East, OSU, Stillwater, OK 74078. Make payment to the OSU Cooperative Extension Service." An incredible resource all in one book.

The "Garden Gurus" program, with Roger Swain and Felder Rushing, hosted by the Purchase Area Master Gardeners was fantastic. I was impressed that consumer horticultural organizations and sponsoring members of the nursery/landscape industry cooperated to present this great gardening gathering. Special thanks to Kathy Keeney, McCracken County Extension Horticultural Agent and Carolyn Roof, Paducah Sun Gardening Editor. Watch for future program announcements by this group in this newsletter or the Paducah Sun newspaper.
