Pandemic-related travel restrictions and the cancellation of large in-person conferences has made it difficult to share our knowledge of trees, but we’re adapting as best we can. Conference platforms and sites like Zoom, Whova and Vimeo save the day, and make it possible for you to view our presentations, too . . . .
JFS represented at Denver Tree Diversity Conference
Keith Warren was among the stellar tree experts who presented at the 2021 Denver Tree Diversity Conference Webinar on March 5. Retired from JFS after a 40-year career as horticulturist, plant breeder and New Plant Development Director, Keith presented, “New Deciduous Tree Cultivars and Suggestions for Denver,” His suggestions included a number of trees he developed at our nursery. Others were drawn from The Tree Book, which he co-authored with Dr. Michael Dirr over a period of five years following his retirement in 2015. His list of trees, recommended for Denver/Front Range communities and similar challenging climates, is shared HERE.
Presented online by Denver Botanic Gardens and University of Denver Chester M. Alter Arboretum, the conference was the seventh annual gathering of tree experts at which Guy Meacham, Nancy Buley and Keith Warren have all presented in prior years. Start planning today to attend the 2022 event, which organizers anticipate holding in-person at Denver Botanic Gardens.
Ontario arborists and urban foresters learn tree timelines
Trees from Seed to City
Timelines to Market and the How and Why of Cultivar Development
It’s a long and complex journey from seed to city tree. Those who attended the ISA Ontario conference, Trees, Virtually Imagined, learned that many hands and a decade or more are needed to grow a tree from start to finish. Our video revealed that developing new and improved cultivars is a multi-generational effort at JFS.
Conference presenter Nancy Buley shared the complex production timeline and numerous pathways that lead to the development of new cultivars. Understanding how and why of new cultivar development helps urban foresters plan ahead for acquiring the best trees for the future urban forest, she said. Though tailored for an Ontario, Canada audience, the process of new cultivar development applies to tree stewards around the world. Download the timeline handout here.
Mastermind event suggests trees for Kansas and beyond
Tree Varieties for Kansas and the Midwest is the topic of a KNLA Mastermind Session presented by Nancy Buley via Zoom webinar. Dr. Cheryl Boyer of Kansas State University moderated this third of an online series hosted by Kansas Nursery & Landscape Association. Nancy’s recommendations for 47 tough and beautiful trees for Great Plains landscapes are based on the order history and collective expertise of a dozen longtime Kansas customers.
The majority of recommended trees are Schmidt introductions or co-introductions, including several that originated in Kansas and adjoining states. Many were trialed for regional suitability at the John C. Pair Horticulture Center, Haysville, Kansas. Each of the featured trees is offered by at least one of our Kansas customers. Most will thrive throughout the Midwest and Rocky Mountain states, and beyond. Because if they can be grown in Kansas, they’re tough and adaptable trees! The recording includes a transcript for closed captioning. Many thanks to Kaitlyn Hupp of Loma Vista Nursery for the invitation!
Keith Warren spent many hours during the first five years of his retirement writing and photographing for The Tree Book, published by Timber Press. Big smiles were in order when a pallet of the books arrived at our office in 2019.
