Overview

• Gardeners are advised to soak banana peels in water for at least 24 hours to extract nutrients into a liquid feed.
• Peels can be buried in soil or mixed into compost piles to gradually nourish outdoor plants.
• Banana peels supply essential nutrients such as potassium, magnesium, phosphorus and calcium that support flowering and fruiting species like tomatoes and peppers.
• Since peels lack nitrogen, gardeners should pair them with nitrogen-rich fertilisers or other kitchen scraps for balanced plant growth.
• Indoor use is discouraged because peel treatments can attract fruit flies, so gardeners should rely on alternatives like coffee grounds, tea bags or eggshells inside.
