Care Guide
Watering
Keep soil consistently moist during active leaf and bulb growth; reduce watering as foliage begins to yellow
Fertilization
Apply balanced organic fertilizer at planting time. Avoid high-nitrogen fertilizers, which prioritize leaf growth over bulb development
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of plants and work lightly into the topsoil to avoid disturbing rootsPruning
- Remove yellowing foliage as bulbs mature to direct energy toward bulb growth
- Deadhead spent flower scapes to prevent seed formation and conserve plant energy
- Trim damaged or diseased leaves promptly to reduce the spread of fungal infections
