Clematis need their roots to be kept cool and moist, so plant the base of these clematis in light shade or provide shading with other plants or a dressing of pebbles. No routine pruning is necessary. If the spread of the plant needs to be restricted prune immediately after flowering, cutting back overlong shoots to healthy buds. Apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the base of the plant in early spring.
