Composting is just allowing organic matter to rot. My wife bought two different models of composting bins. One is a bin style, the other is a tumbler style that we loaded with it's first load of grass clippings and moss today.
I truly believe in lazy composting, basically pile it on and let it rot. However, sometimes a good turning is in order to break up the clumps and redistribute fuel from the outside in.
Turned the bin, wetted it down with the hose to bring the moisture content back up. Getting a good mix between well rotted and dry material will speed up the finished product.
Gotta start saving hair to add more nitrogen and sulfur to the compost pile.
