Save yourself work. Pot them as you dig them. Then they may be sprouting in the pots ready for the new buyer.

Hi,
Do you mean divide and pot them in the fall, then sink the pots into the ground? I live in zone 5/6 so everything above ground will freeze totally solid - wasn't sure how that would affect viability.

You can sink in ground but you can also do the take a couple of straw bales or anything you might have to make a low wall. Put the pots in next to each other and cover with leaves. Borrow your neighbors. I would not put a tarp on top but if you have a critter problem you can use any open weave material or just tree and brush branches to hold the leaves in place. After the first couple of rains the top will stop blowing away. If you have extra money you could cover the whole thing in straw.

Go the library or look on line on how pioneers made root or vegetable bins or cellers and you may have a better idea what I am talking about.
