Water regularly during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in autumn and winter to prevent waterlogging.

Ensure good drainage to avoid root rot, especially in containers. Overwatering is more detrimental than underwatering for this species.

Prune after flowering to maintain a tidy shape and encourage bushier growth. Remove spent flower stalks and any dead or damaged foliage. Light pruning can be done at any time to shape the plant.

Heavy pruning is best done in early spring.

Easily propagated from seed sown in spring, either directly outdoors or in a protected environment. Cuttings can also be taken in late spring or early summer and rooted in moist, well-draining compost.

Seedlings may require thinning.

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

Ensure the new pot has adequate drainage holes to prevent water accumulation.
