We have a front wall covered by ivy. We do like it very much, but keep getting remarks that ivy eventually destroys your wall. My usual response is that you often see ivy on century-old buildings and those seem to have survived all right.
So my question is if there really is potential danger in ivy growing on your (brick) walls and should I remove them, or is it just an urban legend and should we enjoy the beauty of it?
