Care Guide

Watering

Water thoroughly when the top layer of soil feels dry to the touch.

Fertilization

Apply a balanced liquid fertilizer diluted to half strength.. Feed only during the active growing season; pause in winter.

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours, strain, and use the liquid to water the plant. Discard the solid peels in the compost to avoid attracting fungus gnats.
Pruning
  • Remove yellowing or dead leaves at the base of the stem using sterilized shears;
  • Prune leggy growth to encourage a bushier appearance;
  • Provide a moss pole or wooden trellis for climbing support, which encourages larger, more mature leaf development.
