Knockout Rose Bush

Anonymous added on September 19, 2011 | Answered

My knockout rose bushes are showing holes in the leaves to the point where the leaves look like lace, some almost completely eaten away and some with brown spots on them. What can I do about this?

It sounds a bit like rose slugs. I would spray them all with some Bayer Advanced insecticide. Make sure to get the spray up under the leaves as well. Spray the roses a couple of times at the intervals listed on the label. Should get rid of them and let the roses generate some new foliage.
