I have a weeping cherry tree that is about 3 yrs old and it is fall now and the leaves look like they are all curled up and dead. Is this natural or is there something wrong with my tree? They aren't falling off or anything so I'm not sure. People keep asking me if it's dying but it seems to always do go in the spring and summer. It gets water everyother day on a drip system that was proffesionaly done. Maybe it's getting to much water. The soil looks damp not dry. Thank you for the help.
