I know how to do it if I buy the seed potatoes. Same way I did it with the sweet potato sets except they did have skinny roots and swiveled up leaves. They looked dead when they got here, but were not. I have read how to do regular seed potatoes so that isn't the problem. I don't know where to buy them, that is the problem.
I suppose maybe Lowes or Walmart has them in the spring? I don't know.
I would not expect Lowes to carry them, more likely Henderson’s Seed on 105 downtown. You could give her a call and find out. If she doesn’t carry them in the spring, she will know who does, or call the county ext agent, they should know also.
