I’m wondering if I can store fresh sunchoke tubers in the freezer and have them stay alive for planting for as long as I want. If I can do that, I could keep tubers in my freezer to swap with people anytime, and not be limited to sending them only when they’re dormant during the winter.
It seems plausible it could work, since they’re hardy to zone 2 and therefore must be okay with sitting in frozen-solid soil all winter. I’ve also left them outside on top of the snow during a snowstorm, and they’ve frozen solid, and been perfectly fine a few days later when a thaw came. (In fact, I’ve been really lazy and left them outside lying on top of the soil for weeks in January before, and they’ve frozen solid every night and thawed completely every day, so they’re probably pretty unbothered by freeze-thaw cycles, too.)
Have any of you guys tried storing sunchoke tubers in the freezer for awhile and then planting them later? If so, has it worked?
