I planted a Clematis Montana a number of years ago. It produces fabulous flowers but each year some or most of the leaves go brown. I water regularly in the summer because it's on a raised bed but each year the leaves turn brown and a white type substance develops on the stem. I am thinking of pulling it up altogether and leaving the Variegated Ivey on its own, anyone got any suggestions?
