Croton Leaves Appear To Be Sawed Off

Question From: FLORIDA
Q: My croton plant which has been growing in the midst of my oak trees for over 30 years and is 15 to 20 feet tall has developed a leaf problem. The leaves appear to be sawed off. They are not falling off. I can’t find any insects or discoloration. I’m wondering if the heat of the summer has affected the plant or it’s something else. Thanks for your help.

A: I can't help you with this one Barbara. Take photos to an independent nursery or garden center for advice. I live in Michigan and these plants are grown as annuals here. Best And Happy Yardening, Nancy
