Pruning will help keep your clematis vines healthy.  Pruning the dense tangle of stems opens the remaining shoots to air and light which encourages healthy growth and reduces the incidence of rot and disease.

This variety belongs to Pruning Group 3 and will flower in summer on new growth from the current growing season. Pruning of group 3 Clematis is needed to prevent your plant ending up as a tangled mess of old and new growth and the blooms only appearing on some areas and not appearing in others. Prune your Group 3 clematis back to around 30cm above the ground or to a set of healthy, strong buds close to ground in early spring.
