In a world that needs to think greener and reduce the amount of rubbish that goes to landfill, having a thriving worm farm is a no brainer. The average size worm farm can effectively recycle the equivalent of one tonne of waste, per person, per year. most people would never give these wrigglers a second thought but they are vital in the health of soils it's no coincidence that where there are no earthworms present there is not much growing. Turn over a forkful of soil in a thriving garden and they'll be right there hard at work.
