5 Ways To Use Dried Banana Peels As A Fertilizer

Besides many other useful Banana Peel Uses in the garden, this Dried Banana Peel Fertilizer is one of the best. Here’re the 5 ways to do this!

1. Sun Dry Banana Skins & Bury in Soil

You can dry out chopped banana peels in an oven, or you can place the chopped banana peels 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.

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 a 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 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. DIY Foliar Spray from Dried Banana Peels

This DIY shows you how to make organic fertilizer using two tablespoons of dried banana peels, and a tablespoon each of eggshells and Epsom salts. Mix all these ingredients together in a blender and pour the end mixture in a spray bottle. Fill with an equal amount of water and shake well. Spray this fertilizer directly on your plants, or on your garden soil. Learn more here!

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

For healthier plants, use dehydrated banana peels in the garden. This is especially good for flowering plants. Just 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.

5. Use Window Screens to Dry the Peels

If you prefer to go the off-grid way for your gardening, then this tutorial will show you how to dry banana skins using window screens and sunlight. Just make sure to 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. 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.
