Oxfordshire, United Kingdom
hello, I have a clematis montana rubens that is getting out of hand [on a wall on strong trellis.]It has finished flowering now and I can see heaps of old dead looking stuff at the back[I know it isnt really dead just old wood!] How much should I trim away to maintain strength and a good shape, don't want to ruin it.What would you do?
