Vines Pruning Guide

Clematis have three main pruning groups that we have simplified as A, B, and C. These groups are based on where the Clematis grows its new flowers. Follow our quick guide below to see when and where you should be pruning your established Clematis vines after their flowering season.

Group	A	B (1 & 2)	C
Flower Time	Spring	Early Summer and Repeat Blooms B1 (Heavy blooms on old growth in May - June followed by a smaller flush on new growth in September) B2 (Blooms simultaneously on old and new growth from June to September)	Late Summer
Flowers on	Old wood	Old & new wood	New wood
When to Prune	After flowering (Summer)	After flowering (Fall / Winter)	After flowering (Winter / Spring)
Where to Prune	Cut out weak or dead stems.	Light pruning with variation in length in late Feb. or March. Remove weak or dead wood.	Cut back to two strong sets of buds as close to soil level as possible.
