This spring, I planted a small Krimson King on my parkway (I live in Chicago).
I've recently noticed that some of the leaves have turned brown and are falling
off. While you might think that this is due to dryness, I think it is the
opposite - because I've planted hostas at the bottom of this tree, I water it
almost daily. Could it be getting too much moisture? If you don't think this
is the issue, what else could be going on with this tree?

Thanks,

BP
