I had two beautiful Clematis Montana grandiflora (CM Alba) planted three years ago. Up to this year the two of them were growing well with a beautiful fragrance, then this spring one of them didn’t grow any leaves etc, and I think it was because of a dog that moved in next door about 6 months ago, and possibly used the soil at the other side of the fence for a toilet. Is there any point of planting another Clematis, or has the soil been destroyed. If I plant another clematis Is there anything I could add to the soil to prevent the same happening?
