Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering in winter, especially if grown in cooler conditions. Avoid waterlogging, as this can lead to root rot.

Prune lightly after flowering to maintain a tidy shape and encourage more blooms. Remove spent flower stalks to prevent seed formation and direct energy into further flowering.

Harder pruning can be done in early spring if needed.

Propagate by seed sown in spring, or by stem cuttings taken in late spring or early summer. Seeds can be sown in well-draining compost and kept at a moderate temperature. Cuttings should be rooted in a sandy compost mix.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a well-draining compost mix, such as a blend of peat and sand, to ensure good drainage.
