Water regularly to keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings. Reduce watering in winter to prevent root rot, especially if grown in cooler conditions.

Ensure good drainage to avoid standing water.

Prune lightly after flowering to deadhead spent blooms and shape the plant. Remove any dead, damaged, or crossing stems at any time of year.

Hard pruning is generally not required; focus on maintaining a tidy appearance and encouraging further blooms.

Propagate from seed sown in early spring, either indoors or directly into the garden after the last frost. Seedlings can be transplanted when they are large enough to handle.

Stem cuttings can also be taken in late spring or early summer and rooted in moist, well-draining compost.

Repot young plants annually in spring as needed, typically when root-bound. Mature plants can be repotted every 2-3 years. Use a well-draining compost mix.

Repotting helps to refresh the soil and provides more space for root development, promoting healthier growth.
