QuestionI have little green worms on my knock-out roses. I've used several kinds of insect rose dust and spray-but they continue to eat leaves. What should I use?
Thank you
AnswerThe little green worms are not insects but caterpillars and they need to be smouthered. They probably hide under the leaves too so that also makes it harder to get rid of them. Mix up 1 teaspoon of liquid dish soap to 1 quart of water and spray them with that plus check under the leaves.
