If it's not the ash borer, what is it?
I read your article about the emerald ash borer but it doesn’t sound like that’s the problem I’ve got. I have a large ash tree and a week ago about 15-20 twigs from branches were on the ground. The leaves looked healthy and the wood looked like something had actually gnawed through it. It was a clean break. Since then, there have been only a few to fall. Do you have any thoughts?
