Care Guide

Watering

Water deeply and consistently, ensuring the soil remains moist but not waterlogged.

Fertilization

Apply a balanced fertilizer to encourage leafy growth.. Avoid high-nitrogen fertilizers once flowers appear, as this promotes foliage over fruit.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute 1:1 with water and apply to the base to boost fruit production. Discard solids in compost to avoid attracting pests.
Pruning
  • Pinch off early flowers on young plants to encourage stronger root and vegetative growth;
  • Prune lower branches to improve air circulation and prevent soil-borne diseases;
  • Remove any yellowing, dead, or diseased foliage promptly.
