Cut the banana peels into small pieces. Cutting the peels into smaller pieces increases the composting process providing you with rich fertilizer faster.
Allow the banana peel and water mixture to sit for several days at room temperature. Stir the banana water once a day. You will notice the water becoming brown as the nutrients are extracted from the banana peels.
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.
