Care Guide

Watering

Water deeply once a week, increasing frequency during extreme heat or drought.

Fertilization

Apply a balanced organic fertilizer as new shoots emerge.. Avoid high-nitrogen fertilizers, which promote excessive leafy growth at the expense of flowers.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours, strain, and use the liquid to water the base of the plant to encourage prolific blooming. Discard solids in compost to avoid attracting pests.
Pruning
  • Cut back dead foliage to the ground in late autumn or early spring before new growth begins;
  • Deadhead spent flower spikes to maintain a tidy appearance, though leaving them can provide winter interest;
  • Divide congested clumps of corms every 3 to 4 years in early spring to rejuvenate growth and improve flowering.
⚠️
