Q.Black leaves on Holly bushes
Holly bushes that have branches and leaves all the way to ground are developing a progressive black coating on leaves from close to the trunk spreading to tips of branches. Our other Holly that are shaped more like a tree with a trunk appear to be okay. Also evergreen bushes near the Holly bushes are dying from inside out. With needles turning Bron. We lie in Eastern TN
This is very common. You are very close to me, and the winter did have some wet periods. This causes infections in the soil, which mostly effect evergreens from my experience. I correct these issues all the time. Wettable sulfur will kill off the infection when applied to the soil. The dead growth will not come back, but it will stop the spread, and let the new growth remain healthy.
