I have a 15-year-old flowering cherry tree in front of my house whose leaves are curling and turning brown. We have had sufficient rainfall. My next-door neighbor has the exact same tree and it is dark green and healthy. What do you think the problem is and what can I do to save my tree?
Several issues could be causing this problem. Leaf curling and browning could be fungal related considering the wetness we have experienced. More likely would be the roots are having difficulty getting water to the leaves because they are rotting in the ground. There also could be some girdling root or cord or wire that may be interrupting the vascular system.
