This species is probably hardy in the mildest areas of Britain but even then it should be given a good mulch if left in the ground overwinter. The top growth tolerates light frosts and plants can be grown in areas with winter snow. The tubers can be harvested in late autumn after the top growth has been killed back by frost and stored over winter. They should be kept in a frost-free place covered in moist soil or leaves. According to some botanists this species is no more than a synonym for C. indica. Cultivated for its edible root in the Tropics, there are some named varieties. The root can be harvested within 6 months from planting out, though larger yields are obtained after 8 - 10 months. In the British climate this probably means 2 years growth is required for good yields[K]. Yields in the Andes range from 13 - 85 tonnes per hectare, with 22 - 50 tonnes being average. Plants are rarely troubled by pests or diseases. Most cultivated forms do not produce fertile seed. There are also sterile triploid forms, these contain a significantly higher proportion of starch though their cropping potential is not known.Slugs love the young growth in spring and can cause serious damage to plants.
