I have two climbing roses Malvern Hills, but only one has developed varying size holes in nearly all of the leaves. These are contained within the leaf, i.e. with the edge of the leaf intact. There appears to be no sign of the culprit in spite of regular close inspection.
Any ideas for dealing with the problem (or leaving well alone) would be gratefully received.
Many thanks, Lorraine
