how do you protect knockout roses from insects and fungus

Question

Zone 7 – – We don’t know much about gardening yet. Our knockout roses look like something is chewing on them or they did last spring.

Answer 1

Knock out roses are pretty resilient but pests do occasionally attack them. If you can, try to identify what kind of pest if eating the leaves so that you can better tailor the solution to them. But, if you are not sure, a general pesticide should help clear it up.
