Several months are required for proper composting of most types of plant litter. If kept moist, a good compost mixture started in early spring should be ready to use as a mulch or turned into the soil by early fall. However, this depends on how the compost pile is handled, whether it is located in the sun or shade, and how often it is turned. A properly prepared compost pile should reach an internal temperature of 160°F within a matter of weeks. Under these conditions, the organic material will be usable within two or three months.
