Answer: Red Wigglers like to eat decaying leaves and other organic matter resting on the soil surface. I think you would be better off leaving them in your compost pile, and spreading the actual compost on the garden. The compost will, in turn, make your garden soil richer which will attract larger, burrowing earthworms. These are the critters that will live in the soil, loosening it and enriching it with their castings.
