Japanese Maple - Leaves Curling
We have had a lot of rain here in the Northeast all spring/summer. My Japanese Maple has been in the ground about 4 years and was probably 3 feet high when I bought it. Just a few days ago all the leaves have curled up. They've not turned any colors yet, just curled up. I don't see any insect issues. I've got lots of hostas planted around the base of the tree and they've been there since I planted it and have never caused a problem. Should I remove the hostas? Or do you think this problem is caused by all the rain? Thanks.
