QUESTION: Which worm is best for composting? Can I just buy some at the bait store, or do they need to be a special kind? I was going to add them to my compost pile. — Ed W
ANSWER: Unless you’re using the vermicomposting method, you don’t need to worry about managing the worms in your compost heap. They’ll crawl in from outside sometimes and will come and go as they please, which is perfectly fine. You don’t need the worms in a regular compost pile, and as a matter of fact, when the pile heats up, the high temperature would kill any worms that were in the heap anyway.
For vermicomposting, the preferred types of worms are red wigglers (Eisenia fetida) and redworms (Lumbricus rubellus).
