Water moderately during the active growing season in spring, ensuring the soil is consistently moist but not waterlogged. Reduce watering significantly as the foliage begins to yellow and die back in late spring or early summer, allowing the bulbs to enter their natural summer dormancy. Avoid overwatering, which can lead to bulb rot.

Pruning requirements for Star of Bethlehem are generally minimal. It is crucial to allow the plant's foliage to yellow and die back naturally after the flowering period. This process enables the bulbs to store energy for the subsequent year's blooms. While not strictly necessary, spent flowers can be deadheaded to prevent unwanted self-seeding, although the plant also spreads effectively via bulb offsets.

Primarily propagated by separating offsets (bulbils) from the main bulb during the dormant period in late summer or early autumn. These offsets can be replanted immediately. It can also self-seed, but bulb division is the most common and effective method for propagation.

When grown in pots, repot every 2-3 years during dormancy (late summer/early autumn) to refresh the soil and divide overcrowded clumps. Choose a pot only slightly larger than the current root ball to encourage flowering. Ensure good drainage.
