Apply light balanced feed as leaves emerge. Use diluted organic fertilizer to avoid burning bulb roots
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle a thin layer around bulbs in early spring to boost soil calcium and reduce bulb rot riskPruning
- Remove spent flower stalks after blooming to direct energy to bulb development
- Trim yellowed foliage only after it has fully died back to avoid damaging the bulb
