Quick facts

  • Buy disease-free seed tubers from a certified grower or seed distributor.
  • Plant seed pieces as soon as the soil warms.
  • Once the green shoots emerge, plan to hill soil up along plants as they grow.
  • Potatoes require more fertilizer than other vegetables.
  • You can dig new potatoes about seven to eight weeks after planting.
  • Harvest mature tubers after plants have dried.

Potatoes grow from seed tubers, not true seed. They originated in the Andes and come in a variety of types, colors and shapes.

Generally, there are russet types that are starchy with brown skins and that are good for baking; red potatoes that can have white, yellow, or red and starchy or waxy flesh; white potatoes with white or yellow flesh; purple colored potatoes; and fingerling types.

Potatoes need sunny locations to grow well.
