Honeysuckle - If it's very overgrown, you can cut back to about 3 or 4 feet.
If not overgrown, just prune the side shoots annually in early spring, to keep it the size you want.

Clematis - it depends on the variety. We need more details about when it flowers and it's name would be a big help.

Hi Dwarf, long time no hear. follow Hywel's advice. when does the clematis flower as that will decide when it needs pruning. mind if you prune it at the wrong time it is unlikely to die, just not flower this coming year.

thank you for your help

Hi how are you? did you prune them? or is it a task you are about to do soon? take care.
