My Aspen tree and snowball tree's leaves are curling and the leaves are a little lighter in color than the normal ones. Is this leaf curl and if so what can I do to treat this problem? If it is something else else, help please.
Deschutes County Oregon
There are several things that can cause leaves to curl. Is it possible for you to take samples of normal and curled leaves from both plants to your local extension office? If not, pictures of the damage would be helpful. Take pictures of top and bottom portions of leaves, any insects that might be in the curled portion and any other pictures that would help us id the problem. Thank you for asking for our help.
