💧
Watering Water deeply once weekly, allowing the top 5 cm of soil to dry between waterings; avoid wetting foliage to prevent fungal disease development
🌡️
Temperature Optimal growth occurs at 21–27°C; temperatures below 10°C stunt growth and prevent fruit set, while temperatures above 32°C reduce pollination

Care Guide

Watering

Maintain consistent soil moisture during fruiting to prevent blossom-end rot

Fertilization

Feed every 2 weeks with balanced, organic fertilizer. Avoid over-fertilizing with nitrogen, which promotes foliage growth over fruiting

Banana peel tea:Soak 2–3 chopped banana peels in 4 liters of water for 3 days, strain, and drench soil around plant bases to deliver potassium without chemical additives
Pruning
  • Remove suckers (side shoots) to focus energy on main stem and fruit production
  • Trim lower foliage to improve airflow and reduce fungal disease risk
  • Train vines to a trellis or stake to support heavy fruit clusters and prevent breakage
  • Remove yellowing or diseased leaves promptly to stop pathogen spread
