Water regularly, especially during active growth, allowing the top 2-3 cm of soil to dry out between waterings. Reduce watering in winter. Ensure good drainage to prevent root rot.

Wilting can indicate thirst, but avoid overwatering, which is more detrimental.

Prune in late winter or early spring before new growth begins to shape the plant and encourage bushier growth. Deadhead spent flowers throughout the season to promote continuous blooming and prevent seed formation.

Remove any dead or damaged stems at any time.

Propagate by seeds sown in spring or by stem cuttings taken in summer. Seeds can be sown in a well-draining seed-starting mix and kept moist and warm. Cuttings should be rooted in a similar medium.

Both methods are generally successful.

Repot young plants annually or biennially in spring as needed, typically when root-bound. Use a well-draining potting mix. For established plants, repot every 2-3 years or when drainage seems compromised.

Choose a pot only slightly larger than the previous one.
