Rescue for bark-stripped maple?
I have a silver maple that I planted last year. This winter some deer came and either rubbed or ate a fair bunch of the bark off its trunk. This spring it leafed out fine, and I was hoping the bark would just scab over and heal itself. So far though, it hasn't. Now that the summer heat has set in, the tree has been looking quite wilted, and a few branches have even lost their leaves. I've been watering it deeply at least once a week, but as soon as it gets hot, it looks wilted again. I'm guessing it might be loosing a lot of moisture through the raw trunk.
Is there any way to save this tree? Or do I have to watch it slowly defoliate and die?
