I'm in Washington state and I have a chestnut tree outside of my apartment. I'd say it's at least 70 years old -- my girlfriend says it's "probably 30 years old" just now. Anyhow, it appears to be dying. It's losing leaves like crazy but is still fruiting like crazy too. The other chestnuts around the 'hood seem to be fine. I've looked some pointers up of course and it could be "blight" or some new and unknown bacteria they've recently discovered in the UK affecting the Horse Chestnut tree there. However, I think it may be water logged. There's this pump that is supposed to pump water away from the tree and building that doesn't work so well. I guess, I'm just asking if anybody knows if it can bounce back. There really is nothing anybody can do short of knocking down the old building I live in in order to save it I think, yet I don't know. I would so hate to see it get chopped down.
Perhaps RI isn't the place to ask, but I know we have some agricultural/botanical minded people here. So maybe somebody knows something. I really hate being able to see the sky through the leaves. It was such a thick canopy just a month ago.
And for RI effect I will leave this just to stay on topic of all things RI:

There is no me. There is no you. There is all. There is no you. There is no me. And that is all. A profound acceptance of an enormous pageantry. A haunting certainty that the unifying principle of this universe is love. -- Propagandhi
