Composting is the process of reusing material from plants and animals that would generally be considered household waste. This material is placed in compost bins and decomposed to be used in gardens instead of using chemical fertilizers. Composting saves money and requires little time. The organic materials are much more easily absorbed by the soil than chemical fertilizers, and have a lesser chance of burning plants. Anyone can create a compost bin, even those with a limited amount of space.
Choose a small container for your mini compost bin. You can use a small aquarium or a large clay pot can as a mini compost bin.
Place 2 to 3 inches of all-purpose potting soil in the bottom of the container and place the container in a warm location such as a back deck or patio. Allow the container to get partial sunlight but not direct sunlight.
Add a variety of organic waste materials to the container as you have them left over. You can add sawdust, leaves, potato peelings, fruit peelings and vegetable scraps. Alternate the layers in the compost bin with soil, fertilizer and waste materials.
Mix in grass clipping or manure or other substances that are high in nitrogen. You can also add several inches of nitrogen fertilizer.
Place 12 to 24 earthworms to the compost bin. The earthworms will help decompose the material by eating it. Their waste will become part of the compost.
Stir the compost every week to mix oxygen into the compost. This will help further break the materials down.
Continue to add layers until the compost bin is full. Your compost will be usable in approximately six weeks. Mini compost bins decompose much faster than large, lawn bins.
