Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogged conditions, as this can lead to root rot.

Allow the top inch of soil to dry out slightly between waterings once established.

Prune after flowering to remove spent flower stems. This prevents seed formation and can encourage a tidier plant habit. Remove any dead, damaged, or diseased foliage at any time of year. Avoid heavy pruning.

Propagate from fresh seeds sown in autumn, as they require a period of cold stratification. Division of established clumps in early spring or autumn is also effective.

Ensure divisions have healthy roots and at least one bud.

Repot established plants when they become pot-bound, typically every 2-3 years, in early spring or autumn. Use a well-draining potting mix.

Ensure the new pot is only slightly larger than the previous one to avoid excessive moisture retention.
