Answer: What you describe sounds like a fungal infection called brown rot. Of course I can't really diagnose the problem without actually seeing it. I'd strongly recommend you take samples of the leaves and small branches to your local Cooperative Extension office for positive diagnosis and recommended control strategies.

Best wishes with your cherry tree!
