🌱 How to Care for Banana to Prevent Thrips?

💧 How to Water

Water when the top 5 cm (2 inches) of soil dries out — roughly every 3–5 days in summer and every 7–10 days in winter. Avoid waterlogging as roots are prone to rot. Always use water at room temperature.

☀️ Lighting

Banana plants need bright, direct or near-direct light — at least 6–8 hours of strong light per day. Indoors, place it at the brightest window available, ideally south- or west-facing. Insufficient light leads to pale leaves and slow growth.

🪴 Ideal Soil

Use a rich, well-draining, slightly acidic soil mix (pH 5.5–6.5). Combine garden soil with organic compost and perlite for good drainage. Avoid compacted soils that retain excess moisture around the roots.
