Care Guide

Watering

Keep soil slightly moist during active leaf growth; reduce watering as leaves begin to yellow and die back

Fertilization

Apply diluted balanced liquid fertilizer once monthly during leaf growth. Use low-nitrogen fertilizer to prioritize bulb development over foliage growth

Eggshell powder topdress:Bake eggshells at 180°C for 10 minutes to sterilize, crush to fine powder, and sprinkle lightly on the soil surface; avoid direct contact with bulb tissue
Pruning
  • Remove spent flower heads promptly to redirect energy to bulb growth rather than seed production
  • Trim yellowing leaves only after they have fully senesced in late spring to avoid damaging the bulb
  • Thin overcrowded bulb clumps every 3–4 years in early summer to improve airflow and flowering performance
