It is possible to accumulate materials in a loose pile but it is better to have an enclosure for the compost. This could be a pit dug 18 inches into the ground of any length and width or an above-ground structure. Either type of structure should be divided with a partition. One side can be used for composting material and the other for usable compost. If space is not available, a single, tall pile can be used.
Fresh material is added at the top and finished compost dug out at the bottom.
Build your compost pile in layers. First add 6 to 8 inches of garden refuse. Each layer of this organic material should be moistened. A little lime also may added to help the process and keep new soil from packing. Add 1 to 2 inches of soil.
