🌱 How to Care for Banana to Prevent Anthracnose?

💧 How to Water

Keep the soil consistently moist but never waterlogged — bananas are thirsty but rot in standing water. Water deeply and often in heat, easing off in cool weather and when growth slows.

☀️ 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.

🪴 Ideal Soil

Plant in deep, rich, organic soil that holds moisture yet drains freely; generous compost and mulch suit its huge appetite.
