Water
Water regularly, especially during dry spells, to keep the soil consistently moist. Avoid waterlogging, as this can lead to corm rot. Reduce watering in late autumn and winter when the plant is dormant.

Watering, pruning, propagation, and repotting details from plant data
Water regularly, especially during dry spells, to keep the soil consistently moist. Avoid waterlogging, as this can lead to corm rot. Reduce watering in late autumn and winter when the plant is dormant.
Deadhead spent flower spikes regularly to encourage further blooming and prevent self-seeding. In late autumn, after the foliage has yellowed, cut back the dead stems to about 5-10 cm above ground level.
This helps prevent fungal diseases.
Propagate by dividing established clumps in early spring before new growth begins. Corms can also be collected after flowering, dried, and stored in a cool, dry place over winter, then replanted in spring.
Repotting is generally not necessary for established outdoor plantings. If growing in containers, repot every 2-3 years in spring to refresh the soil and divide overcrowded corms. Use a well-draining potting mix.
