It has been going on without human help for millions of years. Backyard composting is a great way to conserve the energy it takes to haul your yard trimmings away. You can then spread the finish product on the soil to make it richer in organic matter. Although composting requires no container, you can confine it with various materials. The easiest container is made from thirteen feet of two inch by four inch welded wire fence made into a circle.
Hardware stores carry it in various heights.
The higher the fence you use the more it holds but the harder it is to turn in your vegetable wastes. When you buy your compost bin wire, have them cut it leaving long wires sticking out on one end. These wires can be bent over to fasten the ends together. To turn the pile unfasten the wire hooks and remove the enclosure. Then fork the material from the previous stack over into the empty enclosure.
