Mixing multiple materials is one of the keys to successful composting
The more diverse the mixture of organic waste, the better the decomposition process and the higher the value of the final compost pile. It is possible to either build up the compost pile layer by layer or gradually mix together the available materials on hand. The only important thing is to avoid adding large amounts of the same material to the compost pile at once, for example, adding only leaves or grass clippings.
