Composting is both an easy way to reduce the amount of waste you send to the landfill and a cheap way to get organic matter for your garden. You can construct a bin or buy a pre-made bin from a hardware store.
Locate your compost near a water source so you can easily keep it moist. Your site should be partly sunny, with good drainage.
The pile should be built in layers, each three to four inches deep. First lay down a "green" layer. This can contain grass clippings or vegetable and fruit scraps. Next, add a layer of "brown" materials, such as leaves, twigs, or sawdust. Then add another green layer. Sprinkle soil between all layers.
Moisten each layer as your build the pile, and turn your compost regularly to speed up the composting process. With little effort you can use the compost you produce to create a prosperous garden.
