Prospero corsicum prefers consistently moist soil during its growing season, but avoid waterlogging, which can lead to bulb rot. Reduce watering significantly as the foliage begins to yellow and die back in late spring or early summer, allowing the bulbs to enter dormancy.

Remove spent flower stalks after blooming to prevent seed formation and direct energy back into the bulb. Once the foliage has completely withered and yellowed, it can be cut back to the ground.

Avoid removing green leaves prematurely.

Prospero corsicum can be propagated by offsets, which are small bulbs that form around the parent bulb. Gently separate these offsets during repotting in late summer or early autumn, and replant them in well-draining soil.

Repot Prospero corsicum bulbs every 2-3 years, ideally in late summer or early autumn before new growth begins. Use a well-draining potting mix, such as a blend of loam, sand, and perlite, in a pot with drainage holes.
