The Jerusalem artichoke is a root vegetable that is homely in appearance. Although Jerusalem artichokes might not be the most popular vegetable, their fans find them tasty, resembling a water chestnut, and loaded with health benefits, from being low calorie to containing a substance called inulin that helps regulate blood-sugar levels. Jerusalem artichokes love cooler climates. These plants need a lot of space and can grow up to 10 feet tall, producing sunflowers as foliage, so do not plant them where nearby plants require full sun.
Prepare Jerusalem artichokes for planting in early spring or as soon as the ground can be cultivated.
Purchase seed tubers from a local nursery, or purchase a whole Jerusalem artichoke.
Cut the tubers into pieces about 2 oz., or the size of a hen's egg, with a sharp knife, with at least two buds per piece.
Keep the tuber pieces cool and moist until you are ready to plant them.
Dig a row with your shovel that is 3 inches deep and 3 feet wide.
Plant the tuber pieces 24 inches apart, cover with soil and water well.
Harvest your crop after the first frost.
