Overgrown Montana Clematis
Don't think this 'beast' has been pruned for about 6-8 years. It's climbing an 8ft wall & was originally on horizontal wire supports. The width from the wall is about 2-3ft & without its leaves looks a mess. Buds appearing. Base of trunk about 5-6inches thick.
Any ideas about how I should tackle it? I'm prepared to cut the whole thing back & completly expose the wall. Would it re-shoot?
