Water
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering significantly during its dormant period in late autumn and winter. Avoid waterlogging, which can lead to bulb rot. Ensure good drainage in the pot.
Also known as Queen Lily

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 its dormant period in late autumn and winter. Avoid waterlogging, which can lead to bulb rot. Ensure good drainage in the pot.
Remove dead or yellowing leaves only after they have completely dried out. This allows the plant to reabsorb nutrients back into the bulb.
Deadheading spent flowers can encourage bulb energy to focus on leaf and root growth.
Propagate primarily through offsets, which are small bulbs that grow around the base of the parent bulb. Carefully separate these offsets when repotting and plant them in their own containers.
They may take a few years to reach flowering size.
Repot every 2-3 years, or when the bulb has outgrown its current container. This is best done after flowering or before new growth begins.
Use a well-draining potting mix, and plant the bulb so that the neck is just above the soil surface.
