Care Guide

Watering

Water thoroughly when the top inch of soil feels dry.

Fertilization

Apply a balanced liquid fertilizer monthly.. Dilute fertilizer to half strength to prevent root burn.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Strain and dilute 1:1 with water before applying to the soil. Avoid placing raw peels directly on the soil surface to prevent mold and fungus gnats.
Pruning
  • Prune in early spring to control size, shape, and direction of growth;
  • Remove dead, damaged, or yellowing leaves regularly to improve airflow;
  • Trim back overly long vines to encourage bushier, denser foliage at the base.
