Viron - In your latest post on "It's Time to Prune" you mentioned a workshop earlier this month in Yamhill County where "Our best candidate's for a pruning demonstration were a massive commercial block of espaliered apples, between heavy posts and trained to wires, approximately 15 years old." As an espalier student, I'd love to take a look at this place. Is it possible to tell me the name of it and/or where it is? Thanks (in advance).
I'm interested in the location as well. I'm also just getting into espaliered training/pruning.
Bethanye-You find any good books or online resources for training espaliers yet? I'll be training/pruning my first tier this spring!

Espalier research to date has produced:
"Training & Pruning Your Home Orchard" a Pacific Northwest Extension publication (PNW 400) - has a short-but-sweet section about espalier/palmette.
"The American Horticultural Society Pruning & Training A Fully Illustrated Plant-by-Plant Manual" by Christopher Brickell and David Joyce. There are at least two permutations of this book. It's the "Fully Illustrated Plant-by-Plant Manual" version that - for me - really delivers the goods.
"The Pruning Book, Completely Revised and Updated" by Lee Reich. Another version of what we need to know in plain, simple English.
The Washington County Cooperative Library Services' WorldCat has available copies of "The Lorette System" which I checked out and attempted to comprehend. The photos are inspirational. Interesting - if recondite - perspective. Still don't know exactly what a "brindelle" is.
"The Backyard Orchardist" by Stella Otto. Less about espalier, more about fungi, insects and troubleshooting.
"Western Fruit, Berries & Nuts" by Lance Walheim and Robert L. Stebbins (HP Books). Good, basic fruit growing stuff.
Hope this helps!
