Dead but not Leafless Points to a Water Issue

Q: I have a dead Japanese maple in my back yard that I planted about 15 years ago. It looked great this spring, but then all the leaves suddenly turned brown and died. I have several other Japanese maples in the yard, and they’re all doing fine. Any thoughts? 

A: For a Japanese maple to die like that with all the leaves still on the tree points to a possible water issue. Water is the only thing that can be cut off rapidly, causing leaves to stay on the tree. The water issue could be caused by a beetle infestation blocking water from reaching the branches. To confirm that, look for tiny toothpick-like projections on the trunk and/or branches.
