Yacon replants can be tricky to store. They will rot if too wet, and will be killed by frost. Best kept cool but dryish, but some people get away with leaving them in the ground all winter. I store mine in almost dry spent compost in a box in a frost-free unheated shed.
On the other hand, oca tubers will survive all sorts of mistreatment, - even being left all winter in a centrally heated room.

I have just been onto Wikipedia to find out what Yacon is. Next question - what do you do with them ? On our plots deer and badgers dig up Jerusalem artichoke plants and sometimes potatoes, to get at the tubers, do you have this problem with Yacon ?

Second tasting experience:

Very different now.  Yes they have become much sweeter.  Melon? no - I would say they reminded me of a firm pear, slightly underripe.  Or an Asian pear.

Like them.
