Regular turning of your compost pile is one of those garden jobs that often is forgotten. Turning your pile over does several things:
- Mixes the new items you have added to your pile with your older items.
- Allows air to get to items that may previously have not had it.
- Discourages pesky insects (gnats, flies, mosquitoes, etc.) from gathering and laying eggs by covering food scraps not yet decomposed. This is only an issue if your pile is near where people will be, and therefore they will be pesky.
- Speeds up the decomposition of your pile. In other words, you will have compost that you can use faster. (This is my favorite reason.)
If you are in a cooler climate, or just a down right cold area, you may have to wait till a warmer day. This is especially true if your pile is under snow or otherwise unable to be worked.
