New to the forum and hoping someone can help in identifying what is wrong with my cherry tree. I'm not sure of the variety but its about 14 years old and is normally healthy, producing lots of cherrys. It sits about 10 feet away from another cherry tree and my concern is that whatever is wrong with it might spread. I have attached a couple of photos to help but in short, nearly all the leaves have died and any cherry buds have gone brown and shrivelled, when I snapped the end of a branch there didn't seem to be any sap in there either.
Any help gratefully recieved.
