    • Hi, Cynthia:
      Oca are not deep rooted - tubers are located in the top 1 ft of soil. They may be grown in a large pot as well. They can be eaten at any point. Leaving them out in sunlight for a week or two after harvest to "cure" sweetens them by reducing the amt of oxalic acid in the tubers. Tubers continue to increase in size even after the plants die down from frost and can be dug all winter but remember that mice like them, too, and may harvest for you if left too long.
