Composting worms can be considered the ultimate suburban animal. They’re quiet, cheap, loyal and useful. They don’t need walking, grooming or vets. As a permaculture animal, they excel. They survive entirely on leftovers and waste, and their voracious appetites can reduce landfill contributions by up to half while giving you rich castings and liquid fertiliser.
There are three main worm categories: anecic (deep soil dwellers), endogeic (medium depth soil dwellers) and epigeic (top layer dwellers—composting worms are this type, and over 90% of them are Tigers, Reds or Indian Blues).
