QUESTION: Do you need special worms for compost?
ANSWER: Most people working with compost don’t need to worry about worms, as worms will make their way into the compost pile and out again on their own. The real work of decomposition is done not by worms but by the microorganisms that live inside the compost.
The only type of composting that requires you to introduce worms or otherwise manage them is vermicomposting, which does use a particular type of worm. Vermicomposters rely on red wigglers (Eisenia foetida) or redworms (Lumbricus rubellus).
