Another consideration is convenience for moving volumes of plant materials in and out of the area. Choose a site close to where material will be used, but not highly visible or one that interferes with yard activities. Structures aren't necessary for composting but prevent wind and marauding animals from carrying away plant wastes. Many useful structures for composting can be purchased or built. These structures vary in how well they can be managed to meet the requirements for effective decomposition under Colorado environmental conditions.
Many people cover their compost with plastic to prevent the outer layers from drying too much.
Such covers need to be removed periodically to add more water and plant material and to aerate the mass. A minimum volume of material is necessary to build up the heat necessary for efficient composting. This volume is generally around 36 inches by 36 inches by 36 inches, but well-insulated wood or plastic structures can be smaller and still hold enough heat to compost well. Wastes should heat up within two days if the compost is put together correctly. Structures built of wire also may have drying problems.
