Turning banana peels into fertilizer is a natural and effective way to provide nutrients for your plants. Banana peels are rich in potassium, phosphorus, and other essential minerals that promote healthy plant growth—without the need for chemical fertilizers. With just a few simple steps, you can create a nutrient-rich organic fertilizer at home.

Materials Needed

• Banana peels: 2–3 peels, either fresh or slightly dried

• Water: 1 liter

• Container: A glass jar, plastic container, or any food-safe container with a secure lid

• Knife or scissors

• Strainer

• Measuring cup (optional)

5 Steps to Make Banana Peel Soak Fertilizer

Step 1: Clean and cut the banana peels

Wash the peels thoroughly to remove any dirt or pesticide residue. Cut them into small pieces (about 1–2 inches) using a knife or scissors. This increases the surface area, making it easier to extract nutrients.

Step 2: Place the peels in a container

Add the chopped peels to your container. Make sure the container is large enough to hold both the peels and the water, with room for stirring or shaking.

Step 3: Add water

Pour 1 liter of water into the container, making sure the banana peels are fully submerged. You can use either filtered or tap water.

Step 4: Let the mixture soak

Close the lid tightly to prevent contamination or odor. Let the mixture soak at room temperature for 24–48 hours. Shake or stir the container occasionally to help extract nutrients evenly.

Step 5: Strain and store

After soaking, strain the mixture to separate the liquid fertilizer from the leftover banana pieces. Store the filtered liquid in a watering can or spray bottle for easy application.

Tip: Don’t throw away the leftover peels. Add them to your compost pile or bury them in the soil to release nutrients slowly over time.

How to Use Banana Peel Fertilizer

• For soil: Pour the liquid fertilizer directly into the soil around the base of your plants. Use about 1 cup for small plants and 2–3 cups for larger ones.

• For foliar spray: Transfer the liquid into a spray bottle and mist it onto the leaves. This method works well for houseplants and flowering plants.

Recommended usage: Apply once every 1–2 weeks for best results.

Reusing banana peels not only reduces kitchen waste but also provides a natural, cost-effective nutrient boost for your garden. It’s a simple and sustainable gardening tip every plant lover should try.
