Care Guide

Watering

Keep soil consistently moist during active growth; apply a 2-inch mulch layer to retain moisture

Fertilization

Apply balanced slow-release fertilizer when new shoots emerge. Avoid high-nitrogen fertilizers which can promote foliage over blooms

Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water for 3 days, dilute 1:20 with water for root drench; discard solid debris to prevent odor and pest issues
Pruning
  • Deadhead spent blooms promptly to redirect energy to bulb growth instead of seed production
  • Cut back foliage only after it turns completely yellow and dies back naturally to allow nutrients to return to the bulb
  • Remove damaged or diseased stems immediately to prevent the spread of fungal pathogens
