A Report on the 2017 Southeast Region Conference in Bowling Green, Kentucky
The Baker Arboretum in Bowling Green, KY, hosted this year’s ACS Southeast Regional Conference on June 9th – 11th. The conference opened with a social hour and dinner at the Augustine Alumni Center on the beautiful campus of Western Kentucky University. There were approximately 65 members in attendance, including nine first timers.
Larry Stanley of Stanley and Sons Nursery kicked off the program with a fascinating discussion of miniature conifers, those that grow less than one inch per year. He described his adventures in Europe visiting the plantsmen who seek out and propagate rare witch’s brooms. They seem to be an obsessive bunch who record the provenance, including GPS location, of each of the hundreds of varieties they discover. Larry brought quite a few miniature conifers for the fund raising auction, spreading this obsession to the rest of us.
Kevin Collard of Pine View Nursery followed with a discussion of his own obsession for boxwood. We learned about the wide variety of sizes, shapes, textures and colors available, much greater than most of us realized. Some of the most important information he provided was about how to correctly prune boxwood. Contrary to popular landscaping practice (shearing), boxwood should be selectively pruned to thin them a bit by using hand pruners to remove whole branches much as you would a tree. If you select the right variety, you’ll be able to toss your hedge clippers as it will never get too large for its space.
We spent Saturday at the Baker Arboretum, with ample time to roam the gardens and converse with fellow coniferites. The staff had the Arboretum in tip top shape. As the reference garden sponsor for the arboretum, I can tell you that the place looks amazing throughout the year. I would recommend taking time to see the garden in every season. The conifers feature prominently year round, but with a dusting of snow and the deciduous trees bare in the winter it is magical! Of course in the fall the Japanese maple collection really shines.
On the grounds of Baker Arboretum, there is also the Downing Museum, featuring the works of world famous Kentucky artist Joe Downing and rotating exhibitions of contemporary regional artists. Joe is one of only three American artists to have work displayed in the Louvre! The museum was designed and situated on the grounds to provide amazing views of the Arboretum from inside, where you can take a break from the heat or cold, depending on the season you visit.
The conference activities scheduled at the Arboretum centered on using conifers in containers. Kevin Collard started with a demonstration of making papercrete troughs, which are easy to make, lightweight, and can be custom made to any size or shape you like. The material has a long history of being used as an economical building material and is weatherproof. It consists of 3 parts shredded, pulped newspaper, 2 parts Portland cement, and 1 part perlite. There are many websites with various recipes and techniques. Everyone had the opportunity to make one or two containers that they could use to grow one of the miniature conifers available in the auction!
Rickman Freeman followed with a discussion of using conifers to create floral arrangements. Freeman has had experience gardening and designing floral displays for numerous country music stars as well as at the Opryland Hotel in Nashville prior to coming to work at the Baker Arboretum as a horticulturist. He discussed tips for making cut plants last longer – cutting stems while they are submerged in clean water is the key. In Ikebana (Japanese floral design) there are three elements – air, earth, and man. These are represented by the different levels in the plants and the container. ‘Rickebana’ is Freeman’s adaptation of these elements to create wonderful displays that can last for over a month and bring the garden into your home. The beautiful centerpieces he created for the tables in the Augustine Alumni Center showed us a whole new way to use conifers.
John Wall, a bonsai professional and member of the Nashville Bonsai Society, showed us how we could combine our conifers and containers to create an amazing work of art that could last for centuries! He discussed the basics of what bonsai is, how to create and maintain bonsai, and what bonsai doesn’t have to be. In its most basic form, bonsai is a tree in a pot. The restricted root space stunts the tree that, when trained, can appear to be a miniature version of an ancient tree. He considers bonsai to be 30% art and 70% horticulture. If you don’t maintain good soil, treat for pests, and fertilize your bonsai you could end up with a stick in a pot. He brought some amazing examples for us to see. A rocky mountain juniper that was estimated to be over 500 years old was collected in the mountains of Colorado where the harsh conditions of five centuries shaped it into an amazing sculpture. He did some maintenance pruning of a bald cypress that he collected from a Tennessee swamp and which has since won awards and been shown at the prestigious Artisan’s Cup bonsai exhibition.
After spending the day at the Arboretum, we made it back to the Augustine Alumni Center where Mike Balogh of Mountain Meadows Nursery was presented with the Outstanding Service Award for his many years of dedication to the American Conifer Society SE Region.
After dinner, Dr. Bill Fountain of the University of Kentucky discussed the evolution of conifers and how they made it from the supercontinents of Laurasia and Gondwana to where we find them growing today. Gymnosperms (conifers, ginkgo, and cycads) began to appear about 400 million years ago while the oldest angiosperms (flowering plants) didn’t appear until about 125 million years ago. He discussed how trees and pests co-evolved over time and how our modern world has introduced invasive pests that plants have no resistance to, such as hemlock woolly adelgid and emerald ash borer. He also talked about how trees form reaction wood in response to physical stresses such as wind and gravity. Conifers form compression wood to prop up a weak limb from the underside, while angiosperms form tension wood on the upper side to pull up a weak limb. These changes can be apparent on the outside of a tree and can help determine whether the tree is adequately adapting in response to stress or if it is at a greater risk of failure.
The fund raising plant auction was very successful. We had 337 plants donated (24 live auction and 313 silent auction) which were auctioned off for a total of $7352! Huge thanks go out to our donors. The proceeds from the auction are very important, because they allow us to support our regional reference gardens through grants.
Following the meeting, a few gardens/nurseries were open for tours. Dr Mark Patton of Bowling Green opened his garden which had a well-manicured collection of conifers, Japanese maples, hydrangeas, and roses. Paul Schneider opened his garden in Portland, TN to us, showing off his amazing collection of conifers from a towering 80’ dawn redwood to tiny miniature pines and Chamaecyparis. His sculptures were also on display throughout. Jennifer and Jeff Harvey’s Dirt Dawg Nursery in Watertown, TN was open to visitors and Kevin Collard opened Pine View Nursery in Leitchfield, KY, for those travelling north.
If you weren’t able to make it to Bowling Green, you can still visit Baker Arboretum. It’s open year round. Just make it a stop on your next trip through KY. You’ll be glad you did. And don’t forget to make plans to attend the ACS national meeting June 14-17, 2018. The Southeast Region is hosting it next year in Raleigh, NC. See you there!
