Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogging, as this can lead to root rot. Reduce watering in autumn and winter when the plant enters dormancy.

Ensure good drainage to prevent excess moisture buildup.

After flowering, allow seed pods to develop for natural propagation if desired. Otherwise, cut back the dead stems in late autumn or early spring. This tidies the plant and encourages new growth from the tubers.

Propagate by division of tubers in early spring before new growth appears. Alternatively, sow seeds in autumn or early spring, though tuber development may take longer than with division.

Ensure seeds are fresh for best germination.

Repot infrequently, typically every 2-3 years in early spring. Choose a larger pot with well-draining soil. Handle the tubers gently to avoid damage.

This is best done when the plant is dormant to minimize transplant shock.
