Do not place your pile close to a wooden fence, building or tree because the moisture will cause the wood to decay. Clear the grass in the area to be used to allow access to soil microorganisms. Heat, water and air are essential for the composting process. Your pile should be large enough to hold the heat that decomposition generates, yet small enough to allow air into the center. A good rule of thumb is a minimum of 3 feet by 3 feet by 3 feet and a maximum of 5 feet by 5 feet by 5 feet.
Many people use a compost bin.
You can purchase a pre-made bin at local hardware stores or lawn and garden centers or you can build your own. Composting is like cooking, many recipes exist. Place 3 to 4 inches of chopped brush on top of the exposed soil to allow air to circulate under the pile. Add water to moisten. Spread a one inch layer of soil over the pile.
