The first thing you need to do is prepare the potatoes for planting. When you’re a week away from planting, put the potatoes in a warm spot of sun. Let the sprouts grow to about 1/4” to ½” inches long. Before you plant, cut the large seed potatoes into chunks that are about 2” wide and that each have at least two buds. Let them sit at room temperature for two or three days before planting.
