I had an old beautiful maple tree in my backyard that looks like it is dying. The leaves last year didn't get as big as they usually did and now this year most of the tree did not bud and what ever did is turning brown and drying up. It is June and it should look great not like it is dying. I live in New England. I also notice green on the trunk and limps of the tree. Is there anything I can do to help my tree?
