Earthworm farms will welcome some attention. Gently place the contents in a heap on a piece of black plastic and slowly gather the compost around the edges. The worms will move away from the light and will eventually congregate in the very centre and can be scooped up and replaced in the worm bin with fresh bedding made from Palm peat. This clean up will ensure the contents of the worm farm does not compact and cause drainage problems. The harvested worm compost can be mixed into regular compost and applied to the garden.
