Water consistently to keep the soil evenly moist, especially during the growing season. Avoid allowing the soil to dry out completely. Reduce watering in fall and winter as the plant enters dormancy.

Ensure good drainage to prevent waterlogged roots.

Prune back dead or spent flower stalks after flowering to maintain a tidy appearance. In late fall or early spring, cut back the foliage to the ground to encourage new growth.

Remove any damaged or diseased parts promptly.

Propagation is typically done by division of clumps in spring. Carefully separate the rhizomes, ensuring each section has at least one bud. Replant divisions immediately into well-draining soil.

Repot container-grown plants every 2-3 years in spring, or when they become root-bound. Use a well-draining potting mix. Ensure the new pot offers adequate space for root expansion.
