Something is eating all the leaves on knock out roses but not the flowers. I didn’t really see any insect on them. Leaves totally gone. Will plant come back and what should I do to save my other knock outs
If you are not seeing the pest then it may be slugs which feed at night. Slug Magic slug bait will eliminate them. The plant can re-foliate. I’d suggest bringing a sample of the damage to one of our store managers to ID what is going on.
