Care Guide

Watering

Keep soil slightly moist during active growth and foliage development

Fertilization

Light, balanced feed once after blooming to nourish corms. Use diluted, low-nitrogen fertilizer to support corm health

Eggshell powder top-dress:Crush dried eggshells into fine powder; sprinkle lightly around corms in early spring to boost soil drainage and calcium content
Pruning
  • Remove spent flower heads to prevent unnecessary seed formation and redirect energy to corm growth
  • Allow foliage to die back naturally before trimming to ensure corms store enough energy for next year's blooms
  • Thin overcrowded corms every 3–4 years in summer to maintain blooming vigor
