Bananas ripen quickly, and many people end up tossing them once they become overripe or rotten. However, instead of throwing them away, you can transform rotten bananas into an all-natural fertilizer that enhances plant growth, improves soil health, and reduces food waste. This eco-friendly method is simple, effective, and perfect for any home garden!

🌱 Why Use Rotten Bananas as Fertilizer?

Rotten bananas contain essential nutrients that plants need to thrive, including:

✔ Potassium – Strengthens roots and improves disease resistance.
✔ Phosphorus – Encourages flowering and fruit production.
✔ Calcium – Strengthens cell walls and improves soil structure.
✔ Vitamins & Minerals – Provides micronutrients for overall plant health.

💡 Bonus: Fermenting bananas enhances nutrient availability and creates a liquid fertilizer that plants absorb more efficiently!
