Say goodbye to store-bought fertilizers with this simple, effective DIY recipe! Using everyday kitchen scraps like banana peels and coffee grounds, you can create a natural fertilizer that nourishes your plants, saves money, and supports sustainable gardening.

Why Use Banana Peels and Coffee Grounds?

🍌 Banana Peels provide:

  • Potassium – Enhances overall plant strength and improves disease resistance.
  • Phosphorus – Promotes flower and fruit development.
  • Calcium – Supports strong root growth and improves soil structure.
  • Magnesium & Manganese – Boost chlorophyll production and enzyme activity.

☕ Coffee Grounds offer:

  • Nitrogen – Stimulates green leafy growth.
  • Organic Matter – Improves moisture retention and soil texture.
  • Mild Acidity – Ideal for acid-loving plants like roses, tomatoes, and blueberries.

When combined, these ingredients become a balanced, nutrient-rich fertilizer suitable for most plants.

What You’ll Need

  • 3 banana peels (any type)
  • 3 tablespoons of used coffee grounds (unsweetened)
  • 1 liter of chlorine-free water
  • Blender
  • Strainer or cheesecloth
  • Spray bottle or watering can

Step-by-Step Guide

1. Prepare the Ingredients

  • Dechlorinate Water: Let tap water sit uncovered for 24 hours to allow chlorine to evaporate.
  • Blend the Peels: Chop banana peels into pieces and place them in the blender.
  • Add Coffee Grounds: Mix in the coffee grounds and the dechlorinated water.
  • Blend Well: Blend for about 3 minutes until the mixture is smooth.

2. Strain the Mixture

Use a fine strainer or cheesecloth to separate the liquid from the solid pulp. The liquid will be your fast-acting fertilizer.

3. Apply the Fertilizer

  • Pour the liquid into a spray bottle or watering can.
  • Apply it around the base of your plants, avoiding direct contact with leaves.

How Often to Use

  • Apply once a week for best results.
  • Suitable for indoor and outdoor plants.

Bonus: Reuse the Leftover Pulp

Don’t throw away the solids! Instead:

  • Mix it into your garden soil or potting mix.
  • Bury it near plant roots.
  • It acts as a slow-release fertilizer and boosts soil microbes.
