Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings.
Reduce watering significantly during the dormant period in summer to prevent bulb rot.
Deadhead spent flowers to prevent seed formation if desired. Remove any yellowing or dead foliage in late spring or early summer as the plant goes dormant.
Avoid cutting back healthy green leaves, as they replenish the bulb for the next season.
Propagate by offsets, which are small bulbs that form around the parent bulb. Carefully separate these in late summer or early autumn before planting.
Seeds can also be sown in autumn, but flowering may take several years.
Repot every 2-3 years, ideally in late summer or early autumn, just before new growth begins. Use a well-draining potting mix.
This allows for division of overcrowded clumps and ensures the bulbs have adequate space and fresh nutrients.
