Main Page | See live article | Alphabetical index In agriculture, hilling is the technique of piling soil up around the base of a plant. It can be done by hand, usually using a hoe, or with powered machinery, typically, a tractor attachment. It is used with certain crops to promote desired growth. A common application of hilling is for potatoes. The tubers grow just below the surface, and can become poisonous if exposed to light (green potatoes). By hilling one or more times during the growing season - effectively, burying the potatoes in an additional few inches of soil - yield is improved, and the harvest remains edible!
