Water moderately when the soil is dry to the touch, typically once a week during the growing season. Reduce watering significantly once the foliage begins to yellow and die back, allowing the bulbs to go dormant.

Ensure good drainage to prevent rot.

Remove spent flower stalks after flowering to prevent self-seeding if desired. Cut back the foliage only after it has completely yellowed and died back naturally in late summer.

This allows the plant to store energy in the bulb for the following season.

Propagate by dividing overcrowded clumps in late summer or early autumn, just before replanting. Seeds can also be sown in autumn or early spring in well-draining soil.

Division is generally more reliable for flowering the following year.

Repot bulbs every 2-3 years, or when they become overcrowded and flowering diminishes. This is best done in late summer or early autumn when the plants are dormant.

Use a well-draining potting mix and plant bulbs at a depth of about 10 cm.
