My wife planted a knockout rose last year and it is blooming fine but has perforation of the leaves all over the plant. Is this normal or does it need to be treated?

Perforated leaves are not normal and are probably caused by rose slugs/sawflies. For more information on rose slugs/sawflies and a course of treatment, please visit the following link:

sounds like insect infestation chemical treatments will work or use volk oil to cover the leaves. natural solution may be to get lady bugs in your garden
