Don’t throw away those banana peels. You can use them as a natural fertiliser for plants. Banana peels are rich in nutrients like potassium, magnesium, and calcium which promote stronger plant growth.
Potassium and magnesium contribute to stronger stem and plant root growth and improve nutrient distribution. Calcium supports plant growth by helping to break down nutrients in the soil and distributing them throughout the plant’s system.
Banana peels are especially beneficial for tomato plants. The potassium in the peels is crucial for healthy fruit production, and the calcium it contains can help prevent blossom end rot (when the bottom of the tomato starts to turn brown), a common tomato issue.
A simple way to use them is to keep banana peels in a covered container or jar of water for 1-2 days then pour the water at the base of your tomato (or other) plants.
According to a gardening source, you can just refill the container or jar with water as needed, and add new banana peels whenever you consume bananas. As the peels brown over time, simply replace them with fresh ones, creating a sustainable cycle of nutrient-rich organic fertiliser.
Banana-peel water is an easy, effective and safe way to feed your plants regular low doses of nutrients throughout the year. Why not give it a try?
