Water regularly during the growing season, especially in dry periods, ensuring the soil remains consistently moist but not waterlogged. Reduce watering significantly once the foliage begins to yellow and die back in late spring or early summer, allowing the bulbs to dry out slightly for dormancy.

Remove spent flower stalks after blooming to prevent seed formation and direct energy back into the bulb. Allow the foliage to yellow and die back naturally; do not cut it until it is completely brown, as it continues to nourish the bulb for the following year's growth.

Propagation is primarily achieved by dividing crowded clumps of bulbs in late summer or early autumn.

Separate the bulbs carefully, ensuring each division has at least one basal plate, and replant them at the appropriate depth. Seed propagation is possible but is a slower process.

Repotting is generally only necessary when clumps become overcrowded, typically every 3-5 years. This is best done during the dormant period in late summer or early autumn.

Replant the divided bulbs into fresh, well-draining soil at the same depth they were previously growing.
