The Basics

When to plant: February–April (possibly May)

Harvest window

  • Potatoes usually mature 90—120 days after planting (depending on the variety).
  • You can harvest a few at a time and leave the rest until you are ready to eat them. When you "rob" potatoes—for smaller, more tender potatoes—be careful not to damage the plant.
  • Harvest remaining potatoes when the plants wilt and turn brown.

Care overview

  • As the plants grow, mound the soil around the plants until at least 6" of the plants are covered.
  • Maintain soil cover for tubers as they expand. Tubers exposed to light may have bitter-tasting green areas and should not be eaten.
  • Potatoes are sensitive to soil moisture. Maintain a consistent soil moisture as much as possible.
