Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, which can lead to root rot. In hot, dry weather, more frequent watering may be necessary.

Reduce watering during cooler months when the plant is less actively growing.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain shape and encourage vigorous growth. Pinch back young plants to promote bushiness.

Spent flowers can be removed to prevent unwanted seeding.

Propagate from seed sown in spring under glass, or take semi-ripe cuttings in summer. Seeds may require scarification or a period of cold stratification to improve germination rates.

Cuttings should be rooted in a well-draining compost mix in a warm environment.

Repot young plants annually in spring into slightly larger pots. Mature plants can be repotted every 2-3 years, or when root-bound.

Use a well-draining potting mix, such as a peat-based compost with added grit or perlite, to ensure good aeration.
