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.

The structure of the compost pile is determined by the amount of waste that is generated more or less continuously throughout the year. Almost everything biodegradable produced in the garden and indoors can be used to make compost, and in the case of insufficient quantities of different types of waste, the structure of the compost pile can be improved by mixing other substances. For example, coarse material left after the compost has been sieved (material filtered out by a screen) or other crushed material can be put back into the compost pile.

Peat should be avoided. Peat tends to lock in moisture, so when the compost pile becomes too dry, the remaining moisture is held in the peat rather than being available to the small organisms in the pile. In addition, it should be remembered that peat extraction can pose a threat to wetlands, so it should be avoided for ecological reasons.
