How to prune clematis 'westerplatte'

Late winter (February–March) for the light tidy; deadhead or lightly trim after the first flush in late spring. In late winter, remove dead and spindly stems entirely. Cut remaining healthy stems back to the highest strong bud pair — this may be only a light shortening. After the first flowering, deadhead or cut flowered stems back by one-third to encourage the second flush.

Avoid hard pruning, which removes the early flower buds. Tidy lightly in late winter: remove dead and weak stems only, then cut remaining stems back to the highest pair of healthy buds.
