    Default Yacon

    I've grown Yacon again this year but have no greenhouse to overwinter the dahlia like tubers.
    Yacon has a primary and secondary root system. The primary are the large deep rooted tubers which are harvested and the secondary dahlia like roots are used for propagation the following year.

    I know that dahlias tubers can be buried under a hedge where its dry and frost free to preserve them over winter

    I haven't got a hedge, but my idea is to dig up the Yacon, harvest the large roots and re-bury the secondary root tubers deeply in the same position .They will be dug up and started into growth in the Spring.

    I reckon if I bury them 200mm below the ground they should be safe from frost?

    Mine have been left outside the last couple of winters and they have been fine against the elements but have been held back by slug attacks in spring. I have also shoved odd tubers in soil and left in the garage over winter with good effect, so I should imagine anywhere sheltered would be fine. I failed miserably at lifting and storing them dry However, if you can store dahlias you may fair well, cos I suck at that as well

    In a mild winter (like the last one) my yacon roots survived in the soil, but in colder winters they haven't, so I would hedge (har, har) your bets, and keep some in the coolest frost free place you have as well.
