Care Guide

Watering

Keep soil slightly moist during active foliage and bloom periods

Fertilization

Apply diluted balanced liquid fertilizer once monthly during active growth. Use a low-nitrogen fertilizer to promote healthy bulb development rather than excessive foliage growth

Eggshell powder topdressing:Sprinkle a thin layer of crushed, dried eggshell powder around bulb bases in early spring to boost soil calcium content; avoid direct contact with bulb tissue to prevent irritation
Pruning
  • Remove spent flower stalks after blooming to prevent unwanted self-seeding
  • Trim yellowing foliage only after it has completely died back naturally to support bulb energy storage
  • Thin overcrowded bulb clumps every 3–4 years in autumn to maintain healthy growth
