Care Guide

Watering

Keep soil slightly moist during active growth; reduce watering as foliage dies back

Fertilization

Diluted balanced feed once at the start of growth. Use low-nitrogen feed to support bulb development rather than foliage growth

Eggshell powder topdress:Bake and crush eggshells into fine powder; sprinkle 1 tbsp around bulbs in early spring, avoiding direct contact with foliage
Pruning
  • Remove spent blooms to conserve bulb energy and prevent self-seeding
  • Trim yellowing foliage only after it dies back naturally in late spring
