I am trying to see how to store veggies long term so am trying storage over winter. The research I have done for rutabagas and turnips says to pull up. cut off roots and leaves, place immediately in a cold, humid storage area. I put into cardboard boxes with plastic and then newspaper lining. I can periodically spray with light mist of water. I put into basement where the thermostat is set at 40F and it is usually about that for 6 months of the year from fall to spring. Recommendation not to wash before storage.
For the potatoes, recommendation to not wash too, but to cure them at room temperature for a week before storing in a cool, dry and dark room. I have another room (old sauna room) that is dark and cold due to no heat, but does not get below freezing. I will store potatoes there. I have picked out potatoes with many eyes to cut up for next year stored in a small cardboard box that will go into the same cold room.
I had many very small potatoes that were marble sized and buried them all together as a backup plan. I put them together about 2 feet deep, covered with pine needles and then covered with dirt. Put in a stake to be able to find them next year. Near where I will plant garlic this fall and will be covered by the same 2 ft of mulch to insulate from ground freeze. A big experiment and waiting to see what works best!
Next year will try pressure canning.
