Clematis Pruning Guide

Clematis Group One : Flowers January - May

Group One consists of the evergreen and early flowering forms, such as cirrhosa and armandii, as well as the alpina, montana and macropetala types.

Flowers appear on short stalks directly from the leaf axil bud on stems ripened the previous season.
After flowering, new growth is produced that will ripen before winter.
Flowers will appear from these buds the following season.

Prune After Flowering

Trim plants to fit space
Remove any damaged/dead growth
Growth is produced for following season

Clematis Group Two : Flowers May - June

Group Two consists of early, large-flowered and semi-double cultivars, as well as later flowering large flower types.

Previous season's growth.
Current season's growth.
Dead or weak stem from previous season, which should have been removed.

Prune Early Spring

Reduce all growth back to spring bud.
Also remove damaged/dead growth.
This creates a new framework for flowering.

Clematis Group Three : Flowers July - October

Group Three is made up of late flowering, large-flowered cultivars, Jackmanii, viticella and texensis types as well as other late flowering species and herbaceous types.

Current season's growth.

Prune Early Spring
