How to speed up your compost heap.

How to speed up your compost heap.: "Compost piles must hold a minimum of organic material before they will maintain rapid decomposition.
So the pile should be at least 3-feet-by-3-feet and 4-feet tall. Naturally piles can be larger.
Moving leaves to the pile, then chopping them up with a lawn mower or leaf shredder before they go on the pile aids composting considerably, as small particles decompose faster than large ones.

There are other things we can do to accelerate composting and make it more efficient.
As slightly wet leaves decompose quicker than dry ones and rain may not penetrate the pile center, I'd dampen dry leaves before adding them. Ground limestone may also be scattered in if we add a bunch of oak leaves and we're concerned about the acidity they may generate in our pile. Scatter about a pound of lime for every five leaf layers. But do not use lime if your compost will be given to acid loving plants such as mountain laurel, blueberries, azaleas, rhododendrons and potatoes.
Adding lime to compost is an option rather than mandatory. "
