Keep the soil consistently moist but not waterlogged. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler months, but never allow the soil to dry out completely.

Ensure good drainage to prevent root rot.

Prune to maintain shape, remove dead or damaged branches, and improve air circulation. Light pruning can be done after flowering. Avoid heavy pruning, as this can reduce future blooms.

Remove any suckers that emerge from the base.

Propagation is typically done by semi-hardwood cuttings taken in late summer or early autumn. Use a rooting hormone and keep cuttings in a warm, humid environment until they establish roots.

Alternatively, seeds can be sown fresh but are slow to germinate.

Repot young plants annually in spring, and mature plants every 2-3 years, 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.
