Care Guide

Watering

Water thoroughly when the top inch of soil feels dry.

Fertilization

Apply a balanced, diluted liquid fertilizer to support new growth.. Do not fertilize during the winter dormancy period.

Banana Peel Tea:Steep chopped banana peels in water for 24 hours, strain, and dilute 1:1 with fresh water. Use as a soil drench to encourage blooming. Discard the solid peels in compost; do not leave raw peels on the soil surface to avoid attracting fungus gnats.
Pruning
  • Pinch back leggy stems in early spring to encourage a bushier, more compact growth habit;
  • Promptly remove any yellowing, dead, or decaying leaves to prevent botrytis (gray mold);
  • Remove spent flower stalks to redirect the plant's energy back into foliage production.
