Potatoes are usually grown from what is called "seed potatoes," seed potatoes are not true seeds. They're potatoes that are meant to be grown to produce more potatoes. Seed potatoes are dormant, like any other tuberous garden plant, when you buy them. Chitting is a method used to sprout seed potatoes before planting. Last year I grew my potatoes in a bucket on the porch and had great success, even though I never chitting involved. This year I decided to give chitting a try.
