Care Guide

Watering

Keep soil consistently moist but not waterlogged during active growth

Fertilization

Apply diluted balanced bulb feed once when shoots first emerge. Use low-nitrogen, phosphorus-rich feed to support bulb development

Eggshell powder topdressing:Sprinkle 1–2 tablespoons of crushed, dried eggshells around bulb bases in early spring; avoid direct contact with emerging foliage to prevent burning
Pruning
  • Remove spent flower stems after blooming to redirect energy to bulb storage
  • Allow foliage to die back naturally before trimming to nourish the underground bulb
  • Thin overcrowded clumps every 3–4 years in autumn to maintain healthy growth
