Water Crinum moorei regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in winter, allowing the soil to dry out slightly between waterings to prevent bulb rot.

Ensure good drainage to avoid standing water around the bulb.

Prune away any dead or yellowing leaves throughout the growing season to maintain a tidy appearance and encourage new growth. After flowering, cut back spent flower stalks to the base of the plant.

No heavy pruning is typically required for this species.

Crinum moorei can be propagated by separating offsets (bulblets) that form around the base of the parent bulb. These should be carefully removed with some roots attached and planted in well-draining soil.

It can also be grown from seed, though this is a slower process.

Repot Crinum moorei every 2-3 years, or when the bulb has outgrown its container, typically in early spring before new growth begins. Use a large pot with excellent drainage and a well-draining, fertile potting mix.

Avoid disturbing the roots too much.
