This ash tree volunteered from an old burn pile. I was hoping it would develop into a nice shade tree, but I’m afraid it is not to be. This is the first real sign of infestation I’ve seen in our neighborhood. We have a few other ash trees in the yard, and I would hate to lose them. Apparently there are some systemic insecticides available in the last few years, which I’m reading about at http://www.emeraldashborer.info The threshold for surviving is 50% canopy loss, so I think we’ll burn this tree in our woodburner, but will think seriously about treating the others.
