Care Guide

Watering

Keep soil consistently moist during active growth; reduce watering after blooms fade to allow foliage to die back

Fertilization

Apply diluted balanced fertilizer once every 2 weeks during active bloom. Use low-nitrogen fertilizer to encourage bulb development rather than excessive foliage growth

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of bulbs in early spring; avoid direct contact with bulb tissue to prevent irritation
Pruning
  • Deadhead spent flower spikes after blooming to redirect energy to bulb growth
  • Allow foliage to yellow and die back naturally before trimming to avoid weakening the bulb
  • Remove damaged or yellowing leaves during the growing season to improve airflow and reduce disease risk
