You're right, Mary. They don't want cold soil.

You can cut up a tuber and the pieces will grow. I've seen a pro do it at a dahlia show. I doubt if I could do it unless it was a spare tuber from a plant I wasn't thrilled with and didn't care if it worked or not. He didn't say anything about treating it with sulphur or cinnamon and he didn't mention anything about when to pot it.

Could you put your long tubers in disposable aluminum loaf pans with drainage holes made at the bottom? I used the clear plastic lids of Rotisserie Chickens for many of my tubers that were long and they worked well. Even the Styrofoam containers that hold mushrooms do well for oversized tubers.
