Knockout Plant Leaves Get Holes And Disappear

Question From: C. Anderson - NORTH CAROLINA
Q: I have knockouts, just planted them this summer.The leaves start out with holes in them and are completely gone now. I do not see any bugs at all on them. What could this be?

The larvae of rose sawflies will do it. They hang on the bottom of the leaves. Japanese beetles will also do it. A systemic pesticide for roses will take care of them. Best And Happy Yardening, Nancy
