I have two hollies, not sure the type but they are triangluar with red
berries in winter. Anyway they were planted in a low spot and suffered.
Over winter they lost every leaf. So I brought in top soil and lift
them by 4" then gave them about 1 1/2 hollytone, each. This was in
March. They were doing better, infact I had blossoms last weekend. I
noticed that they were getting webs and these flying ant-like bugs so I
sprayed them with Orthoean about two weeks ago. This last weekend I
noticed the first blooms and thought things would be fine.

Now the buds and branches on one holly is turning black. This is the
same Holly that blossomed first. Is there anything I can do now?
