Care Guide

Watering

Keep soil evenly moist during active growth; reduce watering as foliage starts to yellow

Fertilization

Apply diluted balanced liquid fertilizer once every 2 weeks. Use a low-nitrogen fertilizer to promote flower production rather than foliage growth

Eggshell powder topdressing:Crush clean, dried eggshells into a fine powder and sprinkle a thin layer around bulbs in early spring to improve soil drainage and add calcium to prevent bulb tip burn
Pruning
  • Remove spent flower stalks after blooming to prevent unwanted self-seeding
  • Trim yellowing foliage only after it has fully died back to allow the bulb to store energy for next year
  • Divide overcrowded bulb clumps in autumn after dormancy to maintain plant health and flowering performance
