Episode Details

Professor Lynn Long has worked in sweet cherry research and Extension at Oregon State University since 1988. At that time, the main cherry variety being grown was Bing on a Mazzard rootstock, leading to disease and susceptibility to weather pressure. Lynn has been an advocate for diversity in varieties and rootstocks, maintaining a cherry variety trial since 1996, and evaluating nearly 100 varieties and selections for potential adoption by the sweet cherry industry in the Pacific Northwest. He has been instrumental in progressing the use of dwarfing rootstocks and new training systems in commercial orchards. Long has authored many publications and has spoken in grower oriented meetings in 16 countries around the world.

In this episode, Lynn and I discuss the future of sweet cherry production. Lynn believes the future development of tree fruit will emerge when we begin better managing 'the other half of the tree' - the root system.

• How soil health and compost applications contribute to varietal performance
• How modern dwarf rootstocks compare to older varieties
• What is the future of biological and mechanical solutions to automate harvesting
• Successfully reducing bacterial canker with plant nutrition
• ...And more!

Very thought provoking for any tree fruit grower!

Episode 12 - Lynn Long - Highlights

2:45 - What are some memorable moments that have lead Lynn to where he is today?

• In the 90's, cherry production was focused on one single variety. There wasn't a lot of diversity at the time.
• In 1994, Lynn went to Europe and gained knowledge that changed the way cherries are farmed in the US

4:10 - What shift happened, and how did Lynn start managing trees differently?

• Lynn had been researching cherry rootstock
• Lynn saw what farms in Germany, France, Spain, and elsewhere in Europe were doing, and brought this knowledge back to help growers understand

7:40 - How does the vigor of modern dwarf rootstock compared to older varieties?

• A lot of farmers prefer older varieties
• Dwarfing rootstock seen to be more shallow

9:10 - What has been missing in looking at the "other half of the tree"

• Everything from research to management has been focused on only half the tree - the top half.
• We are seeing more and more research being done on what is happening below ground with the tree

11:20 - What are some of the things Lynn has observed to cause him to start to wonde
