Red maple tree
We have one approximate 8 year old red maple tree planted on a hillside that has grown normally with no known problems until late last month. All of the leaves are tightly curled and dry, although not falling off the branches. I looked for evidence of insects including mites, nothing was found. The hill provides good drainage and with above average rainfall water does not appear to be an issue. Any thoughts?
Those are some possibilities that could have led to decline. Since the leaves are dry, it sounds like it will have to be replaced, I'm sorry to say.
