what is the leaf problem on my plum tree

Question

I have a dual plum and the new leaves curl under and shrivel up. I have some leaves on the tree. Can I spray with something? And what is the cause?

Answer 1

I would inspect your tree for leaf curl plum aphids. More information on detection and treatment can be found in the following article:
