A Broadfork is a gardening tool that helps make it easier to turn over soil in your garden. It looks like a really big fork, with two long handles on either side. You stick the broadfork into the soil, move the handles up and down and the broadfork uses its two tines, or metal prongs, to loosen the soil and help it aerate. This helps the soil in your garden to stay healthy, which helps your plants to stay healthy too.
