Red worms feed on organic decaying matter – they have been breaking down organic waste to make natural fertilizer for millions of years, and they are non-migratory. Although red worms are non-migratory, they are adaptable to many environments.

Not all worms thrive under identical conditions, so its best to stick to one type of worm. It is also good to stick to one type of worm if you are interested in maintaining a small scale “worm farm.”
