Water moderately during the growing season, allowing the top 2-3 cm of soil to dry out between waterings. Reduce watering in winter to prevent waterlogging, especially if grown in cooler conditions.

Ensure good drainage to avoid root rot.

Deadhead spent flowers regularly to encourage continuous blooming and maintain a tidy appearance. Lightly prune in late winter or early spring to shape the plant and remove any dead or crossing stems.

Avoid heavy pruning as it can stress the plant.

Propagate from seed sown in spring or autumn under cool conditions. Cuttings can also be taken from semi-ripe shoots in summer and rooted in a well-draining medium.

This species can also self-seed readily in suitable conditions.

Repot young plants annually in spring into slightly larger containers with fresh, well-draining potting mix. Mature plants can be repotted every 2-3 years or when root-bound.

Ensure the new pot has adequate drainage holes.
