I have a Clematis Jackmanii and I am trying to change the laddis it was climbing can I cut my Clematis all back at this time of the year or is it better to wait till spring before it grows back?
Jackmanii's can be cut down now (no need to wait until spring). They are in the group 3 pruning group. Ian
Yes, Jackmanii's should be cut back within 6 to 10 inches from the ground. It will come back full the next year. If your clematis is an old one like mine, the vine will be quite thick at the base and so you should not cut too low, but prune where the active growth splits from the main trunk of the vine. Ian
