Care Guide

Watering

Water deeply but infrequently, allowing the soil to dry out completely between waterings.

Fertilization

Apply a light, balanced fertilizer once at the beginning of the growing season.. Requires very little fertilization; excess nutrients can harm the plant and reduce flowering.

Banana Peel Tea:Steep chopped banana peels in water for 24 hours, strain, and use the liquid to water the plant. Discard peels in compost to avoid attracting pests. Use sparingly.
Pruning
  • Remove spent flower stalks at the base after blooming finishes;
  • Carefully trim off dead or damaged lower leaves to maintain a tidy appearance;
  • Wear thick gloves and eye protection when pruning to avoid injury from sharp leaf spines.
