I have similarly had good results saving them in a bag of dry peat moss in the basement over winter, then potting them up in the spring. I have never cut them into pieces though. Last year, after drying them off and dusting off all the dirt, I wrapped them in Saran wrap until January, then in planted them in pots of dry seed starter mix andkep them in the basement. In spring I wet the mix and brought them into the light and they sprouted. It took longer this way though. I don't think it matters if they're roots or potatoes. I think potatoes are just thickened roots?

I had the same question awhile back. Terry suggested keeping my tubers in their container (I stored them in dry vermiculite). I have moved them to a warm spot in the house, as he suggested, and watered the container a little. I expect sprouts or "slips" to emerge soon, which are very easy to root. I suppose if you have room to plant a whole big tuber and do not want to propogate a whole bunch of new plants from the slips, you can just plant the big ol' tuber when the ground has warmed up, and the vine should come back just fine.

Hi, I have not been on this forum for sometime and just came across this post. I have been storing various bulbs and tubers for several years, and I find the best way to store them is in moist potting soil kept in the basement over winter. I cut off the plant, let the tubers dry a bit so all the dirt can be shaken off and then pot them up. If they are grown in pots, I just cut the stem off, withhold water, and transfer to my basement (dark and fairly cool). I use this method for dahlias, cannas, begonias, vodoo lily, tube roses, oxalis,and sweet potatoes. I have also stored sweet potato tubers in saw dust, but that ws many years ago. Hope this helps.

I dug up ONE tuber a couple of weekends ago. I know there must be more, but I couldn't reach way down inside that planter box - it's about 4' deep. It was about 6" long and about 6" in circumference. Not too big, really. But I put it in my cabinet where I store my potatoes. Looks like a regular old sweet potatoe to me. Moni - yours is HUMONGOUS! Susan
