Best Ways To Use Dried Banana Peels as a Fertilizer

Before you read the recipes, do you know BANANA PEELS contain 42% Potassium? Incredibly high compared to manure’s 0.5% only. Apart from that, banana peels have approximately 3% phosphorus and some other essential plant nutrients like calcium, iron, and magnesium in a rich amount. This is why banana peels are really useful in the garden!

1. Sun Dry Banana Skins & Bury in Soil


You can dry out chopped banana peels in an oven or keep them in the sun under a strainer to help them dry out into banana chips. Scatter the dried bits in the center of the plants and water them in.

Alternatively, you can 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 the flowering plants to have fuller and bright blooms. The potassium content also helps in plant cell development and protects them from diseases

2. Add to the Soil Mix at the Time of Planting


All you need to do is cut the peels into small bits and lay them out to desiccate with the skin facing down on parchment paper or a cookie sheet.

Place them in a slow oven preheated to 170 – 200 degrees F. Once the peels turn black, crisp, and brittle, take out the peels and grind them in a food processor till they become powdery and attain a texture similar to coffee grounds.

Pack some of it in a ziplock bag and store it in the freezer to retain its freshness. Save a few for immediate use, and mix it with your soil to encourage the growth of beneficial soil microbes and facilitate the breakdown and release of nutrients. Learn more here!

3. Liquid Fertlizer From Dried Banana Peels


Make organic fertilizer using two tablespoons of dried banana peels and a tablespoon each of eggshells and Epsom salt.

Mix all these ingredients together in a blender and pour the end mixture into a bottle. Add 2 liters of water and mix well. Pour this fertilizer directly on the growing medium or on your garden soil. It will promote lush growth and will make the plants bushier. Learn more here!

4. Dehydrate Banana Strips & Use as a Side-Dressing


Place the banana strips on dehydrator trays and dry them at a high temperature. They are done when they turn crisp and brown. A temperature of 145 degrees Fahrenheit is recommended. If you don’t have a dehydrator, use your oven on a low setting and keep the door ajar.

Once the peels are dried and cooled, process them into small bits or powder in a blender. After that, use the dried powder as a side-dressing for your plants, but be careful not to pour it directly over the roots.

Alternatively, you can also add a teaspoon of it to the planting hole, but ensure to cover it with a layer of soil or mulch before planting the plant.

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

5. Drying the Peels For Fertilizer


Choose a location that gets direct sun for at least 5-6 hours a day. Use a fiberglass screen instead of a metal one. There are some downsides to this process- the first being that it’s lengthy, as it takes approximately 3-5 days to successfully dry out the peels.

However, drying the peels this way will make it more beneficial for the plants, both in their growth and development. Learn more of this and how to make this banana peel fertilizer here!

6. Organic Fertilizer from Banana Peels


This fertilizer recipe is great for your vegetable garden plants and will encourage 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 keeping them in a plastic zip bag in the freezer for 2 days. After that, place the strips in an oven and dry them at the highest temperature.

Once done, place them into a food processor or blender and make a fine powder. Mix 2-4 teaspoons of this powder in a liter of water and use it on the foliage and growing medium once in 3-5 weeks. Learn more here.

  1. Thank you, I’m dehydrating bananas right now and have tons of peels. Great suggestions. I’ll give some to my indoor worms and process the rest or use them in the various ways that you have suggested.

  2. Lots of good ideas. I use dehydrator for drying but use a coffee grinder for creating a powder,smells so good, which I mix into my planters.
