    Typically next couple days after plants die.
    Dig, brush off most dirt, lay in shop for a few days for skins to harden, brush off again. After a week of better we hang them in them in a gunny sack and use often.

    I usually wait until after the tops have frost killed, but before the soil starts freezing. I'm sure there's probably some physiological change that occurs in the tuber when the tops start to die and stop photosynthesising, but I would suspect that soil temperature is the bigger driver in determining what the tuber does as far as starch/sugar ratio etc. in preparation for overwintering. I don't think I've ever noticed any discernible difference between ones dug earlier vs later, tho it seems logical to speculate that the ones allowed to fully shut down for winter might keep better(?). Optimal storage conditions are said to be 38F, 95%RH, and no condensation, so it seems logical to wait to dig them until the soil temp falls to around 38F....

    I always just wait for the plants to die back fully. Sometimes it's before and sometimes after frosts. Though you can leave them in the ground as long as you like up until it freezes solid. I've already harvested all of mine as of last week. The nights have been 30 to 32 for a couple weeks straight. They'll cure in the closet for a couple more weeks then I'll move them to the root cellar. 106lbs in 40 square feet this year. Beat my goal by 6 lbs.
