Growing Jerusalem Artichokes, also Sunchoke

View the Jerusalem Artichokes page

16 Nov 17 Robert Boardman (Canada - Zone 5a Temperate Warm Summer climate)
I have grown Jerusalem artichokes - sunchokes - for two years. What got left in the ground last Fall grew in the late Spring. After two days of below zero temperatures this week I harvested more than 20kg of tubers from about 15 plants. From reading articles and from growing them I learned I cannot find all the tubers when I dig in the Fall. They must be harvested in the Fall, no tubers will form until day length is less than night length.
