Water regularly during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in late summer and autumn as the foliage begins to die back.

Ensure good drainage to prevent root rot, especially in containers.

Deadhead spent flower stalks to prevent seed formation and maintain a tidy appearance. Remove yellowing or dying foliage in late summer or early autumn once it has naturally withered.

This helps redirect energy to the bulb for the next growing season.

Propagate by dividing established clumps of bulbs in late summer or early autumn after the foliage has died back. Alternatively, sow fresh seeds in autumn or early spring in well-draining compost.

Division is generally the more successful method for reliable flowering.

Repot container-grown plants in autumn or early spring before new growth emerges. Use a well-draining potting mix. Choose a pot that is only slightly larger than the bulb's current size.

Ensure the bulb is planted at the correct depth, with its tip just below the soil surface.
