viburnum disease - wilting leaves
Something's wrong with one of my viburnums. On about 1/3 of the shrub, the leaves are wilting and dying. The leaves on the rest of the shrub look just fine. I can't find any spots or anything on the wilting leaves which are curling under and now getting pretty dry. The branches with the leaves that are wilting all go back to the same "trunk" which I assume I need to prune out. ???
I have several other viburnums and I'm hoping this isn't something that could spread. My sick one is a 'Mohawk' that I planted about five years ago. There's another Mohawk planted about 8 feet away and a viburnum Aurora planted about 8 feet away in the other direction.
I'm in Missouri and we don't have viburnum leaf beetles here yet nor do I see any signs of them.
It may have been stressed from a very dry winter. Otherwise it looked pretty healthy until last week when it started wilting.
