Seed potatoes have not been chemically treated to deter sprouting and are intended for garden planting. Each seed potato will have numerous "eyes" from which the potato will sprout. Seed potatoes are stored in cool, dark conditions from the previous year's harvest. Once they have been exposed to light, the potato is revived from dormancy and will begin to sprout. Seed potatoes can be sprouted before planting, although it isn't necessary.
Spread the seed potatoes over the work surface. Cover the surface with newspaper to protect the surface if the potatoes are going to be placed on a table or countertop.
Turn the potatoes over once a day to expose them to daylight.
Cut and cure the potatoes for planting when the "eyes" have begun to sprout. The cure is complete when the cut portion of the potatoes feels dry to the touch.
