Care Guide

Watering

Reduce watering as foliage yellows and the plant enters summer dormancy

Fertilization

Apply balanced, diluted fertilizer when foliage first emerges. Use low-nitrogen fertilizer to support corm development and bloom production

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle 1 tsp per corm at planting time to improve soil drainage and calcium content
Pruning
  • Allow foliage to die back naturally to transfer nutrients to the corm for next year’s bloom
  • Remove spent flower heads to prevent seed formation and conserve corm energy
  • Thin overcrowded corms every 3–4 years in late summer to maintain planting vigor
