If you are just wanting to have decorative vines again, bring them in after cutting off the vines and store them in mild temps...55 to 65 degrees and keep them dry. I don't know if they would keep better in or out of pots, but they must be kept perfectly dry. All this is assuming that you planted a shoot last spring and not a whole potato.

Yes, it was a shoot I planted. So I guess it will be too cool in the basement. Might try an upstairs closet that probably stays around 60 degrees. Thanks!

Hey MaryK I had sweetpotato leaves for dinner last night, sauted with onions....... Yummy. Before you cut off all those vines, you might want to taste them. Next year, you'll be planting LOTS more.

Well that is interesting. Never heard of that!

The leaves are highly nutritious, full of vitamins and fiber as well as flavor. I love it when I can add things like this to dishes without adding calories. Then I don't have to feel guilty if I over indulge in the results. :)

Cuttings are so easy to root from sweetpotato, I hope you will bring some in to save in water for the winter. You can take cuttings from those cuttings next spring to plant outside.

I did take cuttings, but thought I would have to put them in dirt. Can they stay in the water all winter?

I have not tried all winter, but lots of times, cuttings tend to rot after awhile. I would just take more cuttings from them and start new plants every so often. Then if the first ones rot, you will already have new ones. They make pretty spots of green in the kitchen anyway.
