Gardening experts are encouraging households to repurpose apple peels as a nutrient-rich fertiliser, rather than discarding them. With approximately 9.5 million tonnes of food wasted annually in the UK—70% from homes—this simple practice could help reduce waste while boosting plant health.
Apple peels contain essential nutrients such as potassium, phosphorus, and calcium, which are vital for plant growth and cell development. Unlike the fruit's flesh, the peel has lower sugar content, making it an ideal plant food since high sugar levels can be harmful to plants.
To avoid attracting pests, experts recommend turning peels into a 'fertiliser tea' rather than burying them directly. The process involves slicing peels into small pieces, placing them in a jar with water (500ml for peels from two apples, or 250ml for one), and leaving the jar loosely covered in a cool, shaded spot for three to five days.
After brewing, strain the liquid and dilute it with an equal part of water before pouring it onto the soil around plants. The strained peels can be added to compost for further use. This method allows plants to absorb nutrients immediately, promoting healthier growth.
