Lasagna gardening is a technique that uses layers of organic material to build a desired garden space in order to produce fertile soil. Also known as sheet composting, this gardening technique requires no digging or clearing of grasses and weeds. Instead, the gardener will layer materials such as pine needles or newspaper topped with other natural composting materials.
These composting materials can include things such as coffee grounds, grass clippings, produce scraps and garden trimmings. Over time, these organic materials, along with the layer of paper and the grass underneath, will break down and produce a rich soil that can be lightly turned and planted. The "lasagna" name comes from the layering process.
