Canna bug/slug? problem
Massive Damage on Canna leafs. Can\'t find culprit. they have literally shredded half the beautiful folage. Have sprayed with bug killer but would like to deter next season. Any suggestions?
It could be from Asian Beetles. I have a canna that was damaged this year with multiple holes on the leaves of canna, and found the actual beetles on the plant. I picked them off and killed them, and so far, no more damage on new shoots.
