I dug mine, knocked the dirt off and then washed. Let them lay no more a day or so and they were starting to shrivel from the get go. No clue why. I left them in the ground for at least two weeks after the tops froze which was supposed to toughen up the tubers. So this fall will be another trial and error. Maybe I don't wash them at all, just knock off the dirt, if I cut any, then let them lay a day or so at the most, then saran wrap them. I store in my crawl space in cardboard boxes. The temp stays between 50 and 55 and is probably not dry.
