Care Guide

Watering

Water thoroughly when the top inch of soil feels dry, ensuring excess water drains away.

Fertilization

Apply a balanced, water-soluble fertilizer diluted to half strength.. Do not fertilize during the winter dormancy period.

Banana Peel Tea:Steep chopped banana peels in water for 24 hours, strain, and use the liquid to water the plant. Avoid leaving raw peels on the soil surface to prevent fungus gnats and mold.
Pruning
  • Pinch back leggy stems in early spring to encourage bushier, more compact growth;
  • Remove spent flower clusters to redirect the plant's energy into new foliage;
  • Prune just above a leaf node to stimulate new branching.
