The Best Management Practices Workshop IV: Weed Control for Nurseries, Garden Centers and Landscapers will be offered as the same program by Dr. Larry Kuhns of Penn State at two sites this year. Plan to attend February 17, 2003, Jefferson County Extension Office, Louisville, KY or February 18, 2003, UK Res. & Educ. Center, Princeton, KY. A promotional piece with program and contact information is at <http://www.ca.uky.edu/HLA/Dunwell/BMPFlyer.html ***FIX LINK***> The program and registration flyer for Princeton (programs at both locations are basically the same there are minor changes to the Louisville program) can be seen as a PDF file at <http://dib.uky.edu/hort/sites/www.uky.edu.hort/files/documents/BMPPrgrm03.PDF> or as a printed brochure that Christi (270.365.7541 x 221 or cforsyth@uky.edu) can mail to you.
Perennial Plant Association has named Japanese painted fern, Athyrium nipponicum 'Pictum', as the 2004 Perennial Plant of the Year. At 12-18 inches tall and wide it grows best in partial to full shade and moist, organic soils and is hardy in Zones 4-9. The fronds are shades of gray, green, red and purple. http://www.perennialplant.org
Dick Bir of North Carolina State University's Mountain Horticultural Crops Research and Extension Center at Fletcher, NC has posted his monthly newsletters, I found very informative, to a web site:
Barry Glick, Sunshine Farms and Gardens, Renick, WV, sends out a newsletter Glick Picks that is fun and informative. The Glick Picks archives are found on his web site at http://sunfarm.com/picks/ you can sign up by sending an e-mail to barry@sunfarm.com
I received my copy of the International Plant propagators' Society Combined Proceedings 2001, volume 51 over the Holidays and a quick perusal found Mike Hayman's great paper Plants Found in My Backyard...and Yours©. Of equal interest to the plant propagator is Bob Geneve's Plant Propagation Techniques: A Historical Perspective. UK Researcher Dr. Jack Buxton has two "worthy" articles on his Automatic Controlled Water Table Irrigation System.

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.

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.

SNA rules! This year there were some great papers at the Researcher’s Conference, especially the student competition papers. The booths at the trade show were interesting as always and the Tech Sessions were great, especially if you wanted to hear Dr. Tom Ranney and Dr. Mike Dirr talk about plant breeding and development. Next year SNA will be even bigger as the Ohio Florist’s Association will be a partner in the education and trade show.
Summer Nursery Landscape Meetings Continue with Northern Plant Conference (see Upcoming Meetings) expected to be great. I will highlight a few local ones in chronological order below.

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 Itea, Fothergilla, Taxodium 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, Kent http://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 Kentucky http://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, http://www.ca.uky.edu/HLA/Dunwell/HortMemo.html ***FIX LINK*** ) on cicadas is The University of Tennessee publication, SP341-F, Insects: Periodical Cicadas by Frank A.

The Perennial Plant Association 2002 Perennial Plant of the Year is Phlox 'David'. Ann Trimble, Trimble Field Flowers in Princeton, KY gave us a plant of 'David' Phlox last year and it performed well in the UKREC landscape producing pure white fragrant flowers.

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!
