You will want to let the potatoes warm up before planting. When we ship your see, the potatoes are coming directly out of our cooler, once you receive them you will want them to warm up to the at least the temperature of the soil they are being planted in. Exposing them to light also sarts the growing process. After cutting, you should let the seed pieces heal over for 1 to 2 days, the cut area will form a skin.
You can also green sprout or chit your potatoes, this is a more involved process that we have experimented with. I really like the idea of chitting, but because we are so busy shipping orders in the spring, we are not able to do it for our own potatoes. To chit your potatoes, expose them to light, but not direct sunlight, in preferably cool temperatures, as close to 50 to 55 degrees as possible, for 4 to 6 weeks. Chitting your seed potatoes should result in short, thick sprouts. Make sure not to allow your potatoes to freeze while they are chitting.
