At what point should one lift and dry out the tubers i.e. before or
after the frost hits the plant?

Or as they're in a container can they just be moved into the greenhouse
and left to dry out in in the container?

I grow mine in pots and simply put them under the greenhouse staging where
they will completely dry out idc, I repot in the spring at the first sign of
life.
