To make a worm farm, you will need mud, water, a fruit or vegetable and a big container. First, fill a big container full of mud. Add water to it. Then, cut up your fruits or vegetables. Add your fruits or vegetables to the container full of mud and water. Next, put on some work gloves, grab a spade and collect worms from the outside dirt. You can also purchase them, if you'd prefer. Add the worms to the big container. After about two weeks the worms will start to reproduce. After about four weeks the worms will be ready to be harvested from the worm farm.
