Q.Cherry tree
I have a cherry tree, 13 years old and about 15 feet tall. This year when the pink blossom all fell there were left a lot of brown dead leaves instead of the usual all green. Could this be a sign it is not getting enough water? I live on the south coast. It doesn’t look its usual self. Any help would be appreciated. Kind regards, Chris.

It could be from water deficit - drought stress. Or it could be the result of a fungal or bacterial disease. You live on the south coast where, what country?
