Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering in cooler months.

Ensure good drainage to prevent root rot, especially in container plantings.

Prune after flowering to shape the plant and remove spent flower stalks. This encourages reblooming and maintains a tidy appearance.

Remove any dead or damaged stems at any time of year to promote plant health and prevent disease spread.

Propagate by seed sown in autumn or early spring. Seeds may require stratification. Alternatively, take stem cuttings in late spring or early summer and root them in a moist, well-draining medium.

Softwood cuttings root most easily.

Repot young plants annually in spring, moving them to a slightly larger container. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix.

Repotting revitalizes the plant and provides fresh nutrients.
