Water
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering during dormancy in cooler months, allowing the soil to dry out more. Avoid waterlogging, which can lead to bulb rot.
Ensure good drainage to prevent root issues.
Also known as White Carnathus

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering during dormancy in cooler months, allowing the soil to dry out more. Avoid waterlogging, which can lead to bulb rot.
Ensure good drainage to prevent root issues.
Remove spent flower stalks and any yellowing or damaged leaves at the base. This helps maintain the plant's aesthetic appeal and redirects energy towards bulb development and future blooms.
Prune minimally, as foliage is essential for photosynthesis.
Propagate by offsets that form around the base of the parent bulb. Carefully separate these smaller bulbs during repotting.
They can then be planted in their own pots and treated as young plants, requiring similar care to mature specimens.
Repot every 2-3 years or when the bulb outgrows its container, typically in spring before new growth begins. Use a well-draining potting mix.
Choose a pot that is only slightly larger than the bulb to avoid overwatering issues.
