Care Guide

Watering

Keep soil slightly dry; water only when top 10 cm of soil is completely dry

Fertilization

Diluted balanced liquid feed once every 2 months. Use low-nitrogen feed to support bulb development rather than foliage growth

Eggshell powder top dressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the bulb base, avoiding direct contact with the bulb neck to prevent irritation or rot
Pruning
  • Remove spent flower scapes after blooming to conserve bulb energy for next year's growth
  • Trim yellowing leaves only after they die back naturally to avoid damaging the bulb
  • Divide overcrowded bulbs in early spring; handle bulbs carefully to avoid skin irritation from sap
