Recently, we received a question from a woman who had a waterlogged wormery. She threw the entire contents into the compost bin and now she finds that her compost includes big, happy, healthy composting worms in it. She suspects that the composting worms are tiger worms. This is probably correct, since tiger worms (Eisenia fetida, also known as red wrigglers) are often used in wormeries. They’re great little composters.
