Earthworms Mail-Back, pack of 5
Earthworms (Red Wrigglers/Eisenia fetida) help keep the soil loose - they're Mother Nature's very own spade! These little guys eat and burrow 24 hours a day. All of this tunneling aerates the soil (getting oxygen to the roots), allows for easier root growth and improves water retention. And they speed up the decomposition process in cold composting.
