Jerusalem Artichoke 'Stampede' (Jerusalem Artichoke)

Jerusalem artichokes are propagated from tubers. Select small, healthy tubers about 2 oz (57 g) with 2 to 3 buds on them. Plant early in spring but wait until soil temperatures are above 40 F (5 C.). Soil should be sandy and well-drained, but fertile. Tubers should be planted 3 to 5 inches (8 to 13 cm) deep, 15 to 24 inches (38 to 60 cm ) apart, in rows 36 to 42 inches (90 to 100 cm) apart. Tubers will begin growing by August but should not be harvested until tops are killed by frost. Care should be taken as it is impossible to find all the small tubers at harvest so if no more plants are desired pull the new shoots in spring as they emerge before they can set more tubers.
