Cut the banana peels into small pieces. Cutting the peels into smaller pieces increases the composting process providing you with rich fertilizer faster.
Start by building a base layer of twigs or straw at the bottom of your compost pile. Then, add layers of organic materials such as kitchen scraps, banana peels, yard waste, and garden clippings.
Add the banana peels to a glass mason jar. Fill the mason jar and screw on the lid. Allow the banana peels to sit at room temperature for several days.
After three to five days, strain the banana peel water using a cheesecloth or fine mesh strainer. The remaining liquid is your banana peel compost tea.
Dilute the banana peel fertilizer compost tea with water at a 1:5 ratio (one part tea to five parts water). Pour the mixture into a spray bottle or watering can and use it to feed your plants.
