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 zip lock 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 breakdown and release of nutrients.
3. DIY Foliar Spray from Dried Banana Peels
This DIY shows you how to make an organic fertilizer using two tablespoons of dried banana peels, and a tablespoon each of egg shells 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.
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, and use a fiberglass screen instead of a metal one.
