Water regularly once established, allowing the soil to dry out slightly between waterings. Young plants require more consistent moisture. Avoid waterlogging, as this can lead to root rot.

Reduce watering during winter or cooler periods when growth slows significantly.

Prune after flowering to maintain shape and size, and to encourage bushier growth. Remove spent flower spikes. Avoid heavy pruning into old wood, as this can stimulate dieback.

Light tip pruning can be done at any time of year to shape the plant.

Propagate from semi-hardwood cuttings taken in late summer or autumn. Use a rooting hormone and provide bottom heat for best results.

Seeds can be sown in spring, but germination can be erratic and may require stratification.

Repot young plants every 2-3 years into a slightly larger pot with well-draining soil. Mature plants are best left undisturbed. Choose a pot with good drainage holes to prevent water accumulation.

Repotting is typically done in spring.
