Care Guide

Watering

Water deeply and regularly to keep the soil evenly moist during active growth and blooming.

Fertilization

Apply a balanced, slow-release organic fertilizer when shoots first emerge from the soil.. Avoid high-nitrogen fertilizers, which promote weak, floppy stem growth at the expense of flowers.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute 1:1 with water and apply to the base of the plant to promote large, vibrant blooms and strong stems. Discard the used peels in a compost bin to avoid attracting pests.
Pruning
  • Deadheading: Remove spent flowers immediately to prevent the plant from expending energy on seed production;
  • Foliage Care: Leave the stem and leaves intact after blooming until they turn completely yellow or brown, as they are needed to photosynthesize and rebuild the bulb's energy reserves;
  • Winter Prep: Cut the dead stem down to ground level in late autumn or early winter.
