Does anyone know what disease this bush might have? It is a Pee Gee Hydrangea I have had for more than 20 years. It has looked beautiful every other year, and I normally have to trim it a couple of times during the blooming season. It began leafing out this Spring and half of the bush looked normal and the other half looked like this. So I cut all of the branches back and then the entire thing ended up in this condition. Now the problem has spread to another hydrangea next to it
