Care Guide

Watering

Keep soil consistently moist during leaf growth phase

Fertilization

Apply diluted balanced fertilizer once monthly. Use low-nitrogen fertilizer to encourage bulb development rather than excessive leaf growth.

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle lightly on soil surface during leaf growth phase; avoid direct contact with the bulb to prevent irritation.
Pruning
  • Cut spent flower stalks back to 5 cm above the bulb after blooming to redirect energy to bulb growth.
  • Trim yellowing leaves once they die back completely in late autumn to maintain a tidy appearance.
  • Remove damaged or rotting bulb tissue during repotting in early spring to prevent spread of disease.
