I have seven of these Soft touch holly across the front of my house and they all looked perfect this summer and I just noticed one was completely dead...brown leaves and it happened so quickly I hadn’t even noticed. What could have happened? We had trimmed them back very aggressively in the spring but they had put out all new growth and looked good all summer long. This particular one was right by my water hydrant so I would have noticed it if it were looking poorly. So I know it was something that happened within the last few weeks. There are no apparent insects on it. I have sprayed them with the same insecticide that I spray around the house foundation for ants and spiders.
