burning bush's leaves are falling off
I've had my burning bushes in for the second summer now. All of a sudden in the last week I noticed toward the back and bottom of the bush the leaves are turning brown, drying up and falling off. I don't see any bugs on the leaves. Is this a fungus maybe? What could be causing this and what can I do before all I have left is just a bare bush? Last summer all of my hollys got a fungus that about killed them. I sprayed them with Mancozeb and it straightened them out. This year they are healthy, with alot of new growth and thriving. I wonder if my burning bushes have a fungus?
