Bedfordshire, United Kingdom
this year my group 3 clematis' have been producing new stems/foliage on last years growth over the last 3-4 weeks.can i still prune them hard ?.
last year i pruned hard down to about 8" above ground in late march...(no early growth tho!) and had fantastic display of flowers.
any answers would be much appreciated
