Wiltshire, United Kingdom
I have just noticed that one of my clematis, an alpina variety, has developed what looks like black spot on the leaves. Can anyone please tell me what this is , and what, if anything , I need to do. A bit worried it might spread to my other clematis. Incidentally, it is climbing through a climbing rose that does have some black spot. Could that be anything to do with it.
