Planting Jerusalem Artichoke
Planting should be early in the spring, when the soil can be satisfactorily worked. Whole tubers or pieces of tubers that are no less than two ounces and have two or three prominent buds should be planted. Do not allow cut seed pieces to dry before planting. Plant 3 to 5 inches deep, in rows 36 to 42 inches wide with 15 to 24 inches between plants.
Growing Jerusalem Artichoke
Difficult to contain in a garden area - invasive.
Harvesting and Storing Jerusalem Artichoke
Harvest the tubers after the first frost of the year. Tubers dug later in the season are sweeter but have less inulin. The skin of Jerusalem artichokes is very thin; take care when handling to avoid skinning, cuts and bruises. Tubers can be kept for several months if refrigerated at 32 degrees F with 85 to 95% relative humidity. Jerusalem artichokes can be eaten raw in salads, but are generally used in much the same way as potatoes; mashed or made into chips.
