disease on my maples branches
Well I need an ID on this disease my maple has right now. Everything was going and growing fine until last week or two when it seems half of my 6+ yr old maple died off. The branches were turning black and the leaf decayed from the inside out. I cut off the infected areas, threw them far away, as instructed to do by my friend because his mom knows what this disease is. She told him and I that we should be very careful with it, but unfortunately she has passed, so I lost the ID.
Any ideas? I know this one but I cannot for the life of me remember the name and treatment methods.
