How to prune clematis armandii

Immediately after flowering (March–April in the Northern Hemisphere). Cut out dead, diseased, or frost-damaged growth to healthy wood. Shorten overly long stems back to a healthy leaf joint or side shoot. Do not cut bare old stems with no leaves — armandii is reluctant to regenerate from leafless wood. Tie in new growth as it extends.

As needed — annual light tidy after flowering; size control only when necessary. Clematis armandii is an evergreen Group 1 clematis that flowers on previous season's wood. It rarely needs pruning. After flowering in early spring, remove dead or frosted stems and trim any shoots that have grown out of bounds. Hard pruning is possible but slow to recover — avoid cutting into bare old wood.
