I'm in Alsea, OR and planted 10 b. jacquemontii about 12 years ago. One died a couple of years ago and I just figured 'trees die'. But this year I noticed two others looking pretty distressed. In poking around, I learned about bronze birch borer, which apparently showed up in the valley about two years ago. I now understand it's been a serious problem in nearby Corvallis, OR . What a pest! So I have some questions. 1) how do I get rid of it; are the botanists nearby I can contact to see if they can inoculate/treat them? 2) Since they form a sort of allée, I'd like to replant and wonder if you varieties that are are borer-resistant, or have some resistance to them; and 3) where in Oregon can I get them?
Thanks, I appreciate your help!
