Water regularly during the growing season, especially when the soil is dry to the touch. Reduce watering significantly after flowering and during dormancy to prevent bulb rot.

Ensure good drainage to avoid waterlogged conditions.

Remove spent flower stalks after blooming to prevent seed formation and direct energy back into the bulb. Allow the foliage to die back naturally; do not cut it until it has turned yellow and withered, as it nourishes the bulb for the next season.

Propagate by dividing overcrowded clumps of bulbs in late summer or early autumn when dormant. Offsets can be carefully separated and replanted. Seeds can be sown in autumn, but flowering may take several years.

Repotting is generally not required annually for established clumps. If bulbs become overcrowded or flowering diminishes, consider dividing and repotting in late summer or early autumn. Use a well-draining potting mix.
