ð§ How to Water
Keep the soil consistently moist but never waterlogged â bananas are thirsty but rot in standing water. Water deeply and often in heat, easing off in cool weather and when growth slows.
âïļ Lighting
Give full sun for the largest leaves and best fruiting; in very hot climates light afternoon shade prevents leaf scorch. Indoors it needs the brightest possible spot.
