Water consistently to keep the soil evenly moist, especially during active growth. Allow the top 2-3 cm of soil to dry out slightly between waterings. Reduce watering in cooler months.

Avoid waterlogged conditions, which can lead to root rot.

Prune lightly to shape the plant and encourage bushier growth. Remove dead or leggy stems as needed.

Pruning can be done in spring before new growth begins or after flowering to maintain a tidy appearance and promote better flowering next season.

Propagate from seed sown in spring, or from stem cuttings taken in late spring or early summer. Seeds can be sown directly into the garden bed or started indoors. Cuttings should be rooted in well-draining potting mix.

Repot young plants annually or when root-bound, typically in spring. Mature plants may need repotting every 2-3 years.

Use a well-draining potting mix and a pot only slightly larger than the previous one to avoid overwatering.
