Banana peels are an excellent organic fertilizer due to their high content of potassium (K), phosphorus (P), calcium (Ca), and magnesium (Mg)—essential nutrients that promote healthy plant growth, strong root development, and flowering.
Benefits of Using Banana Peel Fertilizer
✔ Rich in Potassium – Enhances plant immunity, root development, and fruit production.
✔ High in Phosphorus – Supports flower and seed formation.
✔ Boosts Soil Microbiology – Encourages beneficial microbes that improve soil health.
✔ Chemical-Free & Eco-Friendly – A sustainable alternative to synthetic fertilizers.
