Care Guide

Watering

Keep soil consistently moist during flowering and early fruiting stages

Fertilization

Apply compost or balanced organic fertilizer at planting. Avoid high-nitrogen fertilizers, as they promote excessive leaf growth over fruit production

Banana peel compost tea:Soak fully composted banana peels in water for 24 hours; dilute the tea 1:20 with water before applying as a root drench to avoid nutrient burn
Pruning
  • Pinch off lateral side vines to direct energy to main vine growth and fruit set
  • Remove yellowing or diseased leaves to improve airflow and reduce pest risk
  • Trim excess foliage around developing fruits to increase sun exposure and speed ripening
