Water regularly during the growing season, keeping the soil consistently moist but not waterlogged. Reduce watering in fall and winter, allowing the soil to dry slightly between waterings.

Ensure good drainage to prevent root rot, especially in container plantings.

Remove spent flower stalks immediately after blooming to encourage further flower production and maintain a tidy appearance. Trim away any yellowed or dead foliage as needed.

Heavy pruning is generally not required, as the plant naturally maintains a good shape.

Propagate by dividing the bulbs in late winter or early spring before new growth begins. Separate offsets and replant them in well-draining soil.

Alternatively, seeds can be sown fresh, but flowering may take several years. Division is the most common and effective method.

Repot every 2-3 years, or when the bulbs have filled the container. The best time to repot is in late winter or early spring. Use a well-draining potting mix, such as a blend of compost, sand, and peat moss.

Choose a pot that is only slightly larger than the current one.
