How to make a low cost compost bin for your garden
What is composting?
Composting is simply decomposing organic material in your back yard in a controlled manner. The organic material can come from a variety of sources:
- Cut grass, leaves
- Food waste (potato peels, etc)
- wood chips
- animal waste (cow, horse, rabbit, etc)
- Meat products, as they smell when decomposing and attract animals
- Bones in open composters, as they also smell and attract animals
- Cloth, plastic
Best Compost uses a right mix of waste - part green, part brown and part food waste. Search for compost recipe for more information. Composting requires a bit of attention, as the compost bins have to be rotated. Compost is made over a one year period, but some materials require more time to decompose properly (ex: animal waste).
Bacteria, earth worms and centipedes all act as decomposers and help your compost become ready faster!
The design of the compost bin has a lot to do with how you are using compost and how often you need it. As a young kid, I've been exposed to a variety of composting methods that my grandma experimented with.She got really good with it and tried a variety of methods, including raised compost piles, worm composting and chemical assisted composting. We did not have many of the high tech innovations available today, so most of composting was done using good old fashioned wooden board boxes
With all the hype around composting, the question arises: why do that? The answer is simple - because this is the right thing to do! It keeps your household and yard waste out of landfills and helps promote the reduce, reuse, recycle lifestyle!
Compost offers several benefits - it is a natural organic soil enhancer (not a real fertilizer). It also allows you to keep a lot of your yard waste, such as grass, leaves, food waste out of landfills.
The good news are that composting is a rather simple activity, but it requires a bit of patience.

It is made out of an old garbage can with cover:

- Create 3 rows of holes around the garbage can to allow for air flow
