My sw potatoes are still in the ground, but probably in a couple weeks, I'll dig them out. Then after curing for a couple more weeks outside, I bring them inside in a large planting pot.(40-50lbs)As we consume them, the rest stay very well over the winter, and I'll keep one large potato to grow my slips in the Spring. Sweet potatoes store very well in a dry place at room temps.

denno -
Do you keep them in dirt in the planting pot, or just in the planting pot?

denno, keeping them outside for a couple of weeks is a nice option in z7, but probably wouldn't work too well in the northern zones. We already had frost near here last night. There was a thread recently on this subject just a little further down the page with a few other good suggestions.

Bart1-I usually put the potatoes in a planting pot without any soil. I do put some paper towels between the potatoes to promote air circulation.
Edweather- Yeah, too cold! So I would put them in a not too cold part of the house, where they would not be too much humidity. The main thing is giving the sweets time to convert the starch to sugar, I believe. You'll love the flavor in the cold months!
