Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Allow the soil to dry out slightly between waterings. Reduce watering significantly during its dormant period in summer to prevent root rot.
Ensure good drainage to avoid waterlogged conditions.
Remove spent flower spikes and yellowing leaves as they appear to maintain a tidy appearance and direct energy to the plant's growth. Minimal pruning is required; avoid cutting back healthy foliage.
Prune only to remove dead or diseased material.
Propagate from offsets or corms. Gently divide the corms during their dormant period in summer. Replant them in well-draining soil, ensuring the top of the corm is just below the surface.
New growth typically appears in autumn.
Repot every 2-3 years, or when the corm has outgrown its container, preferably during its summer dormancy. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the current root ball to avoid excessive moisture retention.
