Composting is a natural process- everything you can compost will decompose without human intervention. Therefore, if you were to throw all your yard wastes and kitchen scraps in a bin and leave them there, sooner or later you would have finished compost. However, following a few simple steps that can take as little as 10 minutes a week can rapidly speed up your composting.
There are plenty of expensive tools you can purchase to speed this process, but a compost pile can be simply a pile of decomposing matter in your lawn or behind your home. Because that can be unsightly and disorganized, another cheap way is to make a U-shaped container by stacking bricks or cinder blocks. Small-scale compost piles shouldn’t exceed 5 cubic feet and shouldn’t be smaller than 1 cubic yard.
To maximize the speed of your compost, you should have a mix of “browns” and “greens”. Browns are things like leaves, dead plants, straw, shredded paper, shredded twigs, pine needles, and sawdust (from untreated wood). Greens include grass, green weeds, manure, seweed/pond algae, and non-meat and non-dairy kitchen scraps.
Ideally, your compost pile should have approximately a 1:3 ratio of greens-to-browns. However, composting is a forgiving process; you needn’t worry too much about the ratio.
You want to avoid composting meat scraps and dairy waste. These wastes decompose differently than plant wastes and often attract unwanted pests.
To jump-start your compost bin, you might consider adding topsoil or finished compost. You don’t have to worry about attracting bacteria and insects that will decompose your material; they come naturally to your pile without any help.
Manure from most herbivores is safe to compost. Do not compost dog or cat manure; they often contain parasites which could remain in your compost and live inside your garden.
Do not compost weeds that have gone to seed- they may grow in your compost or infest your garden.
Your compost pile is supposed to become warm- if not, try adding more greens. If it exceeds 150 degrees, add browns and water to cool it down.
Your compost pile should be about as moist as a wrung-out sponge. If it is too dry, add water. If it is too damp, add browns to soak up the moisture. Too much water will cause the insects and bacteria to drown and emit a foul odor, and too little water will have the same effect.
Try to keep lime out of your compost pile. It promotes ammonia odor problems and increases the pH balance of the compost. Compost should have a pH of about 7 (neutral).
If you are experiencing animal pest problems, try adding dog hair to your compost pile.
From time to time you ought to rotate your compost pile to allow oxygen to enter the center of the pile. This will prevent odors and speed up the composting process. If your pile begins to emit any foul odors, rotate your pile and, if necessary, add water.
