How to Make Banana Peel Fertiliser

Step 1: Collecting Banana Peels

The first step in making banana peel fertilizer is to collect a sufficient amount of banana peels. You can either save them up over time by keeping a container in your kitchen solely for this purpose or gather peels from multiple bananas at once.

Step 2: Drying the Peels

Once you have an adequate quantity of banana peels, it’s time to dry them. Lay the peels flat on a tray or a drying rack and place them in a well-ventilated area. Ensure that the peels are not exposed to direct sunlight as this may cause them to lose their nutritional content. Let them dry for about seven to ten days or until they become dry and brittle.

Step 3: Grinding the Peels

After the banana peels have completely dried, grind them into a fine powder. The powdering process enhances their ability to break down quickly when added to your plants. You can use a blender, a food processor, or a coffee grinder for this purpose.

Step 4: Applying the Fertilizer

Now that you have your banana peel powder ready, it’s time to apply it to your plants. There are multiple ways to use banana peel fertilizer:

  1. Burying the peels: Dig a small hole near the base of your plants and place a handful of banana peel powder into the hole. Cover it with soil and water thoroughly.

  2. Soaking the peels: Soak the banana peel powder in water overnight. The next day, strain the water and use it to water your plants. This water will provide them with the necessary nutrients.

Step 5: Making Slow-Release Fertilizer with Seaweed

If you want a long-lasting fertilizer, you can combine the beneficial properties of banana peels with seaweed. Seaweed is rich in essential nutrients and minerals that can further enhance the growth and health of your plants.

Here’s how you can make a slow-release fertilizer:

  1. Drying the seaweed: Collect fresh seaweed from a clean beach or purchase it from a gardening store. Rinse the seaweed thoroughly in fresh water to remove any salt or debris. Then, dry it in the shade until it becomes brittle.

  2. Grinding the seaweed: Once the seaweed is dry, grind it into a fine powder using a blender or a food processor.

  3. Mixing the ingredients: Take an equal amount of banana peel powder and seaweed powder and mix them together. This mixture will provide a nutrient-rich, slow-release fertilizer for your plants.

  4. Applying the fertilizer: Sprinkle the fertilizer mixture around the base of your plants, avoiding direct contact with the stems. Water your plants immediately after applying the fertilizer to ensure proper absorption.


By using banana peels as fertilizer, you not only reduce waste but also enrich your garden with essential nutrients. From promoting flower blooms to enhancing fruit production, banana peels have a diverse range of benefits for your plants. Additionally, the slow-release fertilizer made with seaweed takes your gardening efforts to the next level. So, why not give it a try and witness the amazing results for yourself?
