First, it may take a little trial and error, but once you get a good C:N ratio, the pile will break down at an optimal speed. Second, piles will break down more quickly in warm months or warm climates. Finally, if you want to speed the composting process even more, you can do what’s called “fast composting.”  According to Clemson, this will produce finished compost in “a couple of months.” This works if you’re starting a new pile. Layer your compost: (aka “lasagna composting”): -- Add a few inches of sticks on the ground to increase airflow and water drainage (optional) -- Add a layer of brown (keep the brown to green ratio about 3:1) -- Add a layer of green -- Mix the layers with a pitchfork or similar tool -- Add moisture if needed (“wet sponge consistency”) -- Add an inch or two of finished compost, manure, or garden soil  -- Repeat, until you run out of organic materials or fill your bin -- Turn the pile twice per week Ideally, you should do this in spring or summer. Note: Make sure your pile, bin, etc., is between 3 feet and 5 feet square. If you have a wire bin, make it at least 3 feet in circumference. The shape doesn’t matter (square, circle, etc.), but it has to be big enough to hold enough heat to decompose.  If all the ratios, moisture, and air are in balance, the pile should start to heat up and reach its hottest point in the first several weeks. Caution: Don’t let the pile get over about 140 degrees Fahrenheit (turn the pile to reduce the temperature). Microorganisms start to die if the temps get too hot.   If you take a temperature reading, the pile should be between 90 degrees Fahrenheit and 140 degrees Fahrenheit for several weeks before the temps start to decline. The decomposition is most efficient in this temperature range, and 140 degrees Fahrenheit is the temperature at which many common weed seeds will die.  Tip: When you take a reading, put the thermometer in the center of the pile at least 12 inches deep. Buy a special composting thermometer for this purpose. They’re easy to find online or in a local home improvement store.
