Keen gardeners can create organic fertilisers from kitchen scraps like vegetable peels, fruit rinds, coffee grounds, and eggshells. These materials are rich in essential nutrients for plant growth. Composting is vital, creating a balance with brown materials like dry leaves, newspaper, or cardboard to enrich soil. Homemade fertilisers promote sustainable gardening practices and help reduce waste and expenses. By recycling kitchen scraps, you can create a healthier garden ecosystem.
