Care Guide

Watering

Keep soil evenly moist during active growth and blooming

Fertilization

Diluted balanced feed once every 2 weeks. Use low-nitrogen fertilizer to promote bulb health rather than excessive foliage growth

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle lightly on soil surface every 2 months to add calcium without burning delicate bulb roots
Pruning
  • Remove spent flower stems after blooming to redirect energy to bulb growth
  • Trim yellowing basal leaves once they die back naturally in late summer
  • Thin overcrowded bulbs every 2–3 years in early spring to improve airflow and reduce competition
