Water moderately during the growing season, allowing the top 2-3 cm of soil to dry out between waterings. Reduce watering significantly in winter to prevent waterlogged roots.

Ensure good drainage to avoid root rot, especially for container-grown plants.

Prune to maintain shape and encourage bushier growth. Deadhead spent flowers to prolong blooming.

Light pruning can be done anytime, but heavier pruning to shape the plant should be done after flowering, typically in late spring or early summer.

Propagate from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds may require scarification or stratification.

Cuttings should be treated with rooting hormone and kept in a warm, humid environment until established.

Repot container-grown plants every 2-3 years in spring, or when root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering issues.

Water thoroughly after repotting.
