Care Guide
Watering
Keep soil evenly moist during active growth and blooming periods
Fertilization
Apply a diluted balanced fertilizer when foliage first emerges. Use a low-nitrogen fertilizer to promote bulb health rather than excessive foliage growth
Eggshell powder top dressing：Crush dried eggshells into a fine powder; sprinkle 1–2 tablespoons around bulb bases in early spring; avoid direct contact with emerging foliage to prevent burnPruning
- Remove spent flower spikes after blooming to prevent unwanted self-seeding (optional)
- Allow foliage to die back naturally to transfer nutrients to the underground bulb
- Thin overcrowded clumps every 3–4 years in late summer to maintain plant vigor
