Q.Weeping Cherry tree
Our Weeping Cherry tree leaves are curling as though it needs water. The surrounding soil feels good, and tree is on a two hour drip every third day. There are no buildings or other plantings near by. We live in Cottonwood, AZ, north of Phoenix about a hundred miles. Any suggestions for the leaf curl?

Also check your tree for any insects which could be causing leaves to curl, including leafrolling caterpillars, aphids, and others.
