Composting can be done largescale or within a small home unit. If doing it on a small scale you will be rewarded in a short time with a valuable soil conditioner which can be applied to your house plants. Too much carbon and material will break down very slowly,Too much nitrogen and you will be able to smell it. The worms are contained in a container which usually can be obtained from garden nurseries,environmental centres,hardware stores etc as a kit. If not using a container from the kit an old dresser drawer,trunk or barrel can be recycled for the purpose.
Wood is best as they are absorbent and good insulators for the worms.
The compost tends too get a bit wet if plastic is used. Worms like a moist,dark environment.basements,balconies,sheds,garages or kitchen counters are ideal. They do need to be kept out of the hot sun,heavy rain or cold. You can get the worms from an existing compost bin,buy them,or find a horse stable or farmer with an aged manure pile. Worms will eat fruit and vegetable peels,pulverized egg shells,teabags,coffee grounds.
