Compost bins have traditionally been placed on the grounds surface. The yard debris is contained by chicken wire and stakes, pallets wired together or wood panels.

Ideally they should be at least 3 to 4 feet wide and as much as 3 to 4 feet high. This size allows for enough material to heat properly. It is this heat generation that occurs as bacteria digest the vegetative material. It is also what promotes very active bacterial growth, which in turn speeds decomposition. 

Woody twigs and dry vegetable material should be alternated with wet green materials such as lawn clippings and immature weeds.

The layering allows for oxygen to aid in breaking down the material. After layering your yard waste the pile needs to be turned or stirred occasionally to make sure all portions of the pile rots evenly, it also provides oxygen into the middle of the pile.

Moisture needs to be constant and the material should be about as wet as a wrung out cloth or sponge. Some times you may need to add water if the pile becomes dry.

To make it easy you should have one or two sides of the bin hinged to allow opening. This will make stirring or emptying the pile much easier.

A good pitch fork or shovel will work fine for the turning process.

The compost will break down to about  half of its original volume when done. Time for this to happen may be 6 to 8 weeks to a year. This material will be a dark brown to blackish brown material that is light and airy. There should be an earthy smell but not in any way offensive.

There are commercially made bins that are stackable and work quite well if you don't want to make your own. One brand, Smith & Hawken Biostack was quite highly rated in Consumer Guide. It was a good buy and rated excellent in composting, convenience and durability.

However, a draw back with this type bin is in stirring or turning your pile over. It is difficult to turn the debris over in the bin as it has no side opening to gain access to the debris. You may need to lift the stacking rings off and fork the composting material onto the ground or into another bin to completely stir the pile.
