Care Guide
Watering
Keep soil evenly moist during active growth and blooming; reduce watering as blooms fade
Fertilization
Apply balanced slow-release fertilizer once at the start of new growth. Avoid high-nitrogen fertilizers to prioritize flowering over foliage development
Eggshell powder + banana peel tea：Crush eggshells into fine powder and mix into the top 2 cm of soil; steep banana peels in water for 3 days, dilute 1:10 for root drench to avoid nutrient burnPruning
- Remove spent flower stalks immediately after blooming to redirect energy to rhizome growth
- Trim brown or damaged leaf tips with sharp, sterile shears to maintain a tidy appearance
- Divide overcrowded clumps every 3–4 years in late summer to reduce competition and promote healthy blooming
- Cut back yellowing or dead foliage in early spring to make space for new growth
