Description

Clematis like to grow in full sun, with afternoon shade in hot summer areas. However, roots should be shaded by mulch or groundcover.  Clematis prefer moist, well-drained soil with a neutral to slightly alkaline pH, Clematis is deep-rooted, so water thoroughly. Stems are fragile and should be handled gently. 

Clematis are divided into pruning groups:

Group 1 plants bloom on old wood and require no pruning except to control the size, in which case prune lightly after flowering back to a pair of healthy buds. 

Group 2 plants bloom first on old wood and then again on new; prune lightly in early spring to shape and remove weak growth and then prune after bloom if desired.

Group 3 – plant flowers only on new wood and can be cut to the ground in fall or spring.
