I have a 8 foot tall autumn blaze red maple. We had it planted (it was a 6 footer) about 3 years ago. It's been doing well, it seemed, until earlier this spring when I noticed the bark was splitting about 1-3 feet up the tree, on the southwest side of the tree. Also, some of the leaves on the very ends of the branches were starting to turn red/brown. Contacted a local nursery they told me that it's "winter scald." We also have clay soil (western 'burbs of Chicago, Zone 5).
Just wondering - can winter scald 'heal' somehow? I've read about tree wraps or putting white latex paint on the tree, but is it too late for that? Is there any sort of 'fertilizer' or medicine I can give the tree to heal? Even though now it seems the leaves have gone green again, is this tree slowly dying, or will it die eventually?
Thanks for your help/tips!! I appreciate it!!
