Turning Your Compost

Unless speed is a priority, frequent turning is not necessary. Many people never turn their compost piles. The purpose of turning is to increase oxygen flow for the microorganisms, and to blend undecomposed materials into the center of the pile. If you are managing a hot pile, you'll probably want to turn your compost every 3 to 5 days, or when the interior temperature dips below about 110 degrees F.

After turning, the pile should heat up again, as long as there is still undecomposed material to be broken down. When the temperature stays pretty constant no matter how much you turn the pile, your compost is probably ready. Though turning can speed the composting process, it also releases heat into the air, so you should turn your pile less frequently in cold weather.

There are several ways to help keep your pile well aerated, without the hassle of turning:

• Build your pile on a raised wood platform or on a pile of branches
• Make sure there are air vents in the sides of your compost bin.
• Put one or two perforated 4-inch plastic pipes in the center of your pile.
