weeping cherry tree

Question

A weeping cherry tree that was planted last fall really looked great and still does. However, at the ends of the branches, the new little leaves are starting to curl and turn yellow. The upper leaves are still vibrant green. I’m at a loss what to do.

Answer 1

Your tree is not getting enough water.

A deep watering of a trickle of water at the base of the trunk a few time a week during warm weather.
