How to prune clematis 'niobe'

Late winter to early spring (February–March). Remove all dead or thin stems at the base. Cut healthy stems back to 30–90 cm above ground to the topmost pair of plump buds. If you want the early early-summer flush, keep cuts light (leave more stem); for simplicity, a hard cut to 30–45 cm works well and the plant rebounds quickly.

Annually (late-winter prune; optional light deadhead after first flush). Clematis 'Niobe' is Group 2, producing deep ruby-red flowers on old and new wood. Prune lightly in late winter — remove dead and weak stems, then cut remaining shoots back to healthy buds. A hard Group 3-style cut is sometimes used for simplicity and still produces good results, though it delays the early flush.
