Care Guide
Watering
Keep soil evenly moist during leaf growth phase; reduce watering as bulbs mature
Fertilization
Diluted nitrogen-rich feed every 2 weeks. Discontinue fertilization 4 weeks before harvest to improve bulb storage life
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1 teaspoon per plant around the base and work into topsoil gently to avoid disturbing rootsPruning
- Remove yellowing outer leaves to improve airflow and reduce disease risk
- Cut back flower scapes if growing for bulbs to redirect energy to underground bulb development
- Trim foliage to 5 cm after bulb tops yellow and fall over, then cure bulbs for storage
