I bought some oca tubers in spring and planted it into a pot because the bed was not ready. It's autumn here and getting colder - we're getting frosts to -5°C. What should I do with the oca? I would have a place now but this might be the wrong season to put the plant into the ground.

Oca is cold sensitive.  I would lift them out, pop them in a paper bag and store some where cool and dark ready to plant out in spring.

Some of the ones I planted overwintered in their bed (I thought I had them all!) and re-grew the next year.  However we don't usually get really bad frosts here in N.Ireland.  I doubt they'll have survived winter past.

I was disappointed with their harvest though.  Small and fiddly.  And kids weren't so keen on them.  So I've stopped growing them.  Spuds do much better here!

I doubt that our winters are colder, maybe I put half of it in the soil and the other half in a bag, hung up that the mice can't get them.
