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?
