Perform major pruning in late winter. Summer pruning can control size and shape.

Rake as needed, in early spring, cut the entire clump back to 2 cm - 4 cm from the ground to remove old, tired foliage and stimulate new growth.

Cut back mid to late Autumn or early spring to mounds 40cm high.

Trim any leggy or overgrown stems to encourage new growth.

Deadhead

Cut back by half in winter to fresh lime-coloured leaves in winter.

Dead heading. Cut back stems hard in late winter or early spring to promote new growth.

Cut back to the ground in winter.

Dead head

Formative pruning

Responds well to pruning; tip pruning encourages bushier growth and prevents legginess.

The tree can be pruned or coppiced every few years to maintain a dense, smaller form. For younger plants, light, regular pruning in late winter helps maintain a compact shape.

Cut back every 3-7 years

Pruning after flowering helps maintain shape and control size.

Deadhead and cut back to 20 cm in autumn.

Deadheading and hard cut back late Winter.

Cut to the ground in winter or remove spent flowers and foliage.

Requires minimal care; shear back old foliage in late winter/early spring for fresh new growth.

Cut to ground in winter

Deadheading and hard cut back early spring

Cut the plant back hard to about 20–30 cm above the ground in winter.

Deadhead and remove any dead foliage.

Formative pruning into desired shape

Clip into topiary forms in late spring and deep winter

The best time for significant pruning is in late winter or early spring before new growth begins

Minimal; remove spent flower stalks and any dead/yellowing leaves.

Cut to ground in winter.

Cut back the entire plant to roughly 12 cm from the ground in late winter or early spring (Feb) before new growth appears

Low-maintenance; prune lightly in spring to maintain shape and encourage fullness.

Very low maintenance; doesn't require much pruning, but dead flowers can be removed.

Rake foliage and deadhead over winter. Keep spent flowers for the vase.

In winter, cut back by about half or to new growth.

Cut back to ground in winter

Cut to ground in winter.

Formative pruning, coppicing

Prune to desired height and spread.

Prune after flowering to maintain shape, encourage bushiness, or for a tree form.

Prune lightly after flowering to shape and encourage dense growth; also remove dead wood.
