United States 
my knock out roses are not doing well. Something has been eating them. Many holes in the leaves. I sprayed with Rose Rx 3 in 1. Five rose bushes and only one bloom. I replaced them once before. They are growing
between Golden Barberrys and Nine Barks. Could that
be there problem? They get full sun after 12 noon. They
face the south. Ron

Welcome to GoY! What general area in the States are you in, Ron? It makes a difference in rose care. Also, what kind of holes, and is a picture possible?
