The real question is; Where are you?. Once the sprouts get a couple of inches long, it is usually best to break them off before planting. The potato will resprout in the ground or other growing medium. Potatoes are a cool weather crop. In the south we have to plant them in winter in order to get in in a harvest before the July heat arrives. we can fall plant in August for harvest in November, but results are not as good as in spring. The potato itself is viable until it completely shrivels up.
