Slow Composting

In the slow composting method, yard trimmings are composted in simple holding units or compost heaps. Bacteria and fungi that function at mild temperatures are the actors here. Earthworms, centipedes, beetles, millipedes and other organisms are also involved in the breakdown process. 

Materials to Use

Use the same ingredients as the hot compost pile. Be sure to keep the kitchen scraps out as compost heaps can attract rodents.

Building the Compost Heap

Position the compost heap in a convenient spot out of the wind and direct sunlight. It is helpful to have two heaps; one to use for fresh materials while the other is maturing. Composting piles should be located directly on the soil.
Add yard trimmings as they are collected. By mixing the green and brown materials, and keeping the heap damp (but not soggy), it will help keep the composting process going.

Since materials are continually added to the heap, the more finished compost will be located at the bottom. To harvest the ready compost, remove the holding unit from the compost heap, and place it next to the heap. Next, shovel materials from the top of the old heap into the bottom of the empty holding unit until rich compost is found.
