Those who have grown them what did you do?

Brought them in, and kept them is very slightly damp soil. They
are significantly more frost-sensitive than potatoes.


I think there may have been a misunderstanding, what I meant was when
growing them in the garden did you bank them up like you do when growing
potatoes?

I understand you have to let the plants get frosted at the end of the
season but wait two weeks before digging up the tubers as the goodness
from the top goes back into the tubers. Then, if there is a crop worth
storing I'll probably take your idea and store in damp sand/soil.

When I grew Oca I topped up the compost level, like potatoes they
produce from the stem underground, though they will also throw a few
tubers above ground if the foliage is thick enough to keep the light off.
