I just noticed this tread. Others have given you lots of good advice. Potatoes are really easy to grow and they are very forgiving. I have never pre-sprouted potatoes in my life. I just plant them as Sandy described. If they are large and I cut them, I just cut them leaving at least two eyes as Sandy mentioned, and throw them in the ground, never have had one rot. Some years they have had long sprouts that were not given light, and I planted them. They grew anyway and did well. Some years I will miss one or two when I dig them in the fall, and they will come up the next spring, and produce. Around here in zone 5 the saying goes, plant them on Good Friday, and have new potatoes for the 4th of July. I've had potato peelings sprout in the compost pile. I guess what I'm trying to say is that you should have no problem getting them to grow. I have heard that some people save old tires and fill one with dirt and plant a potato in it. Then as it grows they keep adding more tires and keep filling them with dirt. Supposedly they end up with a lot of potatoes from one plant. I've never tried that trick, not sure I'd like my food grown in tires. Have fun with them, and let us know how they turn out.
