Care Guide

Watering

Water thoroughly when the top inch of soil feels dry, maintaining even moisture.

Fertilization

Apply a balanced, diluted fertilizer to support active foliage growth.. Fertilize only during the active growing season; halt feeding in winter.

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours. Strain and dilute 1:1 with water before applying to the soil. Discard the solid peels in compost to avoid attracting fungus gnats or causing mold indoors.
Pruning
  • Pinch back the growing tips regularly to encourage a bushier, fuller plant;
  • Remove any yellowing, dead, or damaged leaves to maintain plant hygiene;
  • Provide a trellis or moss pole early on to guide the climbing tendrils and prevent tangling.
