Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings, especially during the growing season.

Reduce watering in cooler months, but do not let the soil become completely dry.

Prune lightly after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks to prevent self-seeding, as this plant can be invasive.

For overgrown plants, heavier pruning can be done in early spring.

Easily propagated from seeds sown in spring or late summer. Cuttings can also be taken from young shoots in spring or summer and rooted in moist potting mix. Seedlings require warmth and light to germinate.

Repot young plants annually or when root-bound, typically in spring. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix. Ensure the new pot is only slightly larger than the previous one.
