Organic gardening has grown in popularity due to health and environmental concerns about pesticides. Making compost is a good way to start organic gardening, as compost provides nutrients to help plants thrive without synthetic fertilizers. To make compost, designate an outdoor space and build alternating layers of plant trimmings, leaves, kitchen scraps, and manure, separated by layers of soil. Turn and water the pile over months to yield compost that can be spread in the garden.
