6 ways to use dried bananas or banana peels as fertilizer

We talk about the 6 best ways to use dried banana peels as fertilizer in your garden or vegetable patch, and thus take advantage of its high potassium content to grow the best plants.

There are many uses for banana peel in the garden or orchard, which can help your plants grow better.


Best Ways to Use Dried Banana Peels as Fertilizer.

Before we start, did you know that banana peels contain 42% potassium? Incredibly high compared to 0.5% in manure.

Also, banana peels contain about 3% phosphorus and other essential plant nutrients like calcium, iron, and magnesium in good amounts. This is why banana peels are very useful in the garden or orchard.

1. Dry the banana peels in the sun and bury them in the ground.

You can dry the chopped banana peels in an oven or keep them in the sun under a colander to help them dry into dried banana chunks. Scatter the dry pieces in the garden or orchard and water them.

You can also bury them in the soil of your potted plants or use them as mulch.

As the peels have a high concentration of potassium, they will help flowering plants to bloom more abundantly and brilliantly. The potassium content also helps in the development of plant cells and protects them from disease.

2. Add to potting mix at planting time.

All you have to do is cut the shells into small pieces and lay them skin side down on parchment paper or a cookie sheet to dry.

Place them in a preheated oven at 90°C. Once the shells turn black, crisp and brittle, take them out and grind them into a powdery, coffee-like texture.

Put one piece in a ziplock bag and store in the freezer to preserve freshness. Save a few for immediate use and mix them into the soil to encourage the growth of beneficial soil microbes and aid in the breakdown and release of nutrients.

3. Liquid fertilizer made from dried banana peels.

Compost two tablespoons of dried banana peels and one tablespoon of eggshells and one tablespoon of Epsom salt.

Mix all these ingredients in a blender and pour the final mixture into a bottle. Add 2 liters of water and mix well. Pour this fertilizer directly on the soil of your garden, your plants will thank you.

4. Dehydrate the banana strips and use them as fertilizer.

Place the banana strips on the dehydrator trays and dry them over high heat. They are ready when they turn crispy and golden. A temperature of 60°C is recommended. If you don’t have a dehydrator, use the oven on low and keep the door ajar. Or you can also make one yourself.

After the shells have dried and cooled, cut them into small pieces or grind them into a powder in a blender. Then use the dried powder as a fertilizer for your plants, but be careful not to spray it directly on the roots.

You can also add a teaspoon to the planting hole, but be sure to cover it with a layer of soil or mulch before planting the plant.

It is good for flowering plants, especially roses, and it will help the plant grow at a much faster rate. It will also promote flowering.

5. Dry the shells as compost.

Choose a location that receives direct sun for at least 5-6 hours a day. Use fiberglass mesh instead of wire mesh. This process has some disadvantages: the first is that it is long, since it takes about 3 to 5 days to dry the hulls successfully.

You can also hang them directly in the sun 😉

However, drying the hulls in this way will be more beneficial to the plants, both in their growth and development. Learn more about it and how to make this banana peel compost here!

6. Organic fertilizer made from banana peels.

This compost recipe is ideal for plants in your garden and will promote lush growth. As the peels are a rich source of potassium, they will promote strong rooting, flowering and fruit development.

Dry the banana peels by storing them in a resealable plastic bag in the freezer for 2 days. Then place the strips in an oven and dry them on the highest setting.

Once done, place them in a blender and make a fine powder. Mix 2-4 teaspoons of this powder in a liter of water and use on foliage and growing medium once every 3-5 weeks. You can get more information here.
