Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Reduce watering in fall and winter, allowing the top few centimeters of soil to dry out between waterings.

Ensure good drainage to prevent root rot.

Prune after flowering to deadhead spent blooms and remove any dead or damaged stems. Light pruning can help maintain shape and encourage bushier growth. Avoid heavy pruning, as it may reduce next year's flowering.

Propagate from seeds sown in early spring, either directly outdoors or in a protected environment. Germination can be slow and may require stratification.

Softwood cuttings can also be taken in late spring or early summer.

Repot young plants annually in spring. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix. Ensure the new pot has adequate drainage holes.
