Water regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Reduce watering in fall and winter, allowing the soil to dry slightly between waterings.

Good drainage is crucial to prevent root rot.

Prune after flowering to maintain shape and size. Remove dead, damaged, or crossing branches. For older plants, a renewal pruning in late winter or early spring can encourage vigorous new growth and more blooms.

Avoid heavy pruning in fall or winter.

Propagate from semi-hardwood cuttings taken in summer or by layering in late summer. Seed propagation is also possible but can be slow, and seedlings may not come true to type.

Root cuttings can also be successful in early spring.

Repot young plants every 1-2 years in spring, and mature plants every 3-4 years as needed. Use a well-draining potting mix. Repotting is generally best done in early spring before new growth emerges to minimize stress.
