Response to Anyone grown Jerusalem Artichokes?

We have grown them for many years at a couple of different places in Wisconsin. They will spread slowly, and are difficult to get rid of once established, which isn't a problem for a small patch but can be a problem if you put in a field of them, as any left in the field will grow a new plant next season. You dig them after the frost in the fall, and can use them raw in salads or with dips, etc., or boil them like new potatoes, or use them sliced like water chestnuts in stir fry. They don't seem as good if eaten when the plants are growing, just in the fall and early spring. We have never watered ours, even in the drought of 1988, but then we don't water much in our garden except when planting. I would probably mulch them in a dry area, and we always seemed to miss enough of them every fall when harvesting to insure a crop the next year.
