Water consistently, allowing the soil to dry slightly between waterings. Avoid waterlogging, as this can lead to root rot. Reduce watering during the dormant winter months.

Ensure good drainage in the pot and the soil mix for optimal health.

Prune to remove spent flower stalks and dead or damaged foliage. This encourages continued blooming and maintains a tidy appearance. Light pruning can also be done to shape the plant.

Avoid heavy pruning; focus on maintenance and tidiness.

Propagate by division of established clumps in spring or autumn. Seeds can also be sown in spring. Ensure seeds are fresh and sow in a well-draining seed-starting mix.

Division is generally the most straightforward method for home gardeners.

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

Choose a pot only slightly larger than the current one to avoid excess moisture retention.
