Horseshoe, I dug up my sweet potatoes in late October, giving them as much time to grow as possible. The problem may be that I did not get them in the ground as early as possible. I think, and this is just a guess because of all the things I grow, they were put in the ground after I harvested my garlic in late May. This year I plan on putting them in the raised bed/potato bags in March if frost is past, or April at the latest.
Thanks for all the helpful hints and information.
