Planting & Caring for Seed Potatoes


  • Choose the right location: Potatoes prefer well-draining soil that is rich in organic matter and a sunny spot. Make sure to choose a spot where the soil has a pH between 4.5 and 5.5.
  • Prepare the soil: Remove any weeds, grass, or debris from the planting area and till the soil to a depth of 8 to 10 inches. If your soil is heavy with clay or sandy, mix in compost or peat moss to improve its structure.
  • Cut the seed potatoes: Cut your seed potatoes into pieces, making sure each piece has at least one "eye." Let the cut pieces dry out for a day or two before planting.
  • Plant the seed potatoes: Dig a trench that is 4 to 6 inches deep and space the seed potato pieces 12 to 18 inches apart. Cover the seed potatoes with soil and gently press down to remove any air pockets.
  • Mulch: After planting, add a 2 to 3 inch layer of straw or wood chips around the base of each plant to conserve moisture and suppress weeds.
  • Water: Water your newly planted seed potatoes thoroughly, making sure to moisten the soil around the roots. During the growing season, water the plants at least once a week, making sure to water deeply to encourage deep root growth. During dry periods, water more frequently.


  • Fertilize: Once the plants have established, begin fertilizing them every 4 to 6 weeks with a balanced fertilizer.
  • Hill the plants: As the plants grow, mound soil up around the stems, leaving only the top few leaves exposed. This helps to prevent the developing tubers from getting sunburned.
  • Pest control: Keep an eye out for pests such as Colorado potato beetles and control them as needed using organic methods.
  • Harvest: Potatoes are usually ready to be harvested about 3 to 4 months after planting. Carefully dig around the plants with a garden fork to avoid damaging the tubers.
