Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering significantly during the plant's dormant period, typically in late summer or fall.
Overwatering can lead to bulb rot, so ensure well-draining soil and avoid letting the pot sit in standing water.
Remove spent flower stalks at the base once flowering is complete to prevent seed formation and direct energy back into the bulb. Trim any yellowing or dead foliage in late summer or fall as the plant enters dormancy.
This helps maintain a tidy appearance.
Propagate by offsets (small bulbs) that form around the mother bulb. Gently separate these offsets during repotting in fall or early spring.
Plant them in well-draining soil, treating them similarly to mature bulbs, though they may take a year or two to flower.
Repot every 2-3 years or when the bulbs become crowded. The best time is during the dormant period, typically in fall.
Use a well-draining potting mix, such as a cactus or succulent blend, and ensure the new pot is only slightly larger than the existing root ball.
