I didn't think I could grow them here. All I did was break off some sprouts, root them in water, plant them in little pots, and then moved them to my half barrels with my geraniums to fill in the blank spaces. Today I dug the geraniums out to put them in winter quarters, and discovered several small tubers on the roots of the sweet potato vines. One is about the size of a wiener. This makes me think that maybe I could grow them in my garden in a raised ridge covered with black plastic and watered by drip irrigation. Exciting!
I hope to get some sprouts from the tubers, thinking maybe they'd be acclimated to our cooler conditions.
Anybody in the north with experience growing them? Would yams grow the same way?
