Composting is the process of recycling decomposed (broken down) natural waste. Natural waste includes things such as leaves, or fruit and vegetable scraps. Over time, the natural waste will decompose into a rich soil called compost. Compost can be spread into flowerbeds, dug into vegetable gardens, spread under trees and bushes, or sprinkled on the lawn. Compost can be used anywhere that you want to give a boost of nutrients to the soil.

Good places to set up a compost bin are any place near a garden, and close to a source of water. This way you can easily add to the compost and keep it moist. A workforce of bacteria, earthworms, and other organisms, work to break down the natural waste. This workforce needs air and water to live and work.
