Why Garden Pros Prefer Planting Potatoes in the Fall

Potatoes love the cool weather, and fall is the perfect time to plant them for a head start next season. Fall planting usually starts in late August or early September.1 

Planting when the soil is cooler helps the potatoes sprout faster, giving them a jump on the growing season and a potentially bigger harvest next year.2 Here’s how to do it.

Benefits of Planting Potatoes in the Fall

Planting potatoes in the fall can offer several advantages compared to spring planting, depending on your climate and goals. Here are some key benefits:

  • Extended Growing Season: In regions with mild winters, fall-planted potatoes can continue to grow and develop through the winter, resulting in an earlier harvest compared to spring-planted ones. This is especially beneficial for gardeners who want to enjoy fresh potatoes sooner in the season.
  • Reduced Pest and Disease Pressure: Many common potato pests and diseases are less active in the cooler temperatures of fall and winter. Planting in the fall can help your potatoes avoid these issues, leading to healthier plants and a potentially higher yield.
  • Improved Soil Moisture: Fall often brings more consistent rainfall, providing better soil moisture for newly planted potatoes. This can aid in root establishment and reduce the need for supplemental watering, especially in areas prone to dry springs.
  • Optimized Soil Temperature: Cooler fall temperatures can be ideal for potato growth. Potatoes prefer soil temperatures between 50-70°F, and planting in the fall allows them to establish roots and begin growing when the soil is naturally within this range.
  • Reduced Competition from Weeds: Many weeds tend to slow down or die back in the fall, meaning less competition for nutrients and water for your potato plants. This can lead to stronger growth and healthier potatoes.
  • Efficient Use of Garden Space: Planting potatoes in the fall allows you to utilize garden space that might otherwise be vacant after summer crops. This can maximize your garden’s productivity and provide a continuous harvest throughout the year.
  • Variety Selection: Some potato varieties are better suited for fall planting, offering unique flavors and textures that differ from traditional spring-planted varieties. This can add diversity to your potato harvest and culinary experiences.

Considerations

  • Climate: It’s important to choose potato varieties that are well-suited for your specific climate, hardiness zone, and the length of your growing season.
  • Frost: Protect your fall-planted potatoes from frost damage by covering them with mulch or row covers if necessary.
  • Harvest Timing: If you live in an area with harsh winters, you might need to harvest your potatoes before the ground freezes to prevent damage.

Here are steps on how to plant potatoes during the autumn season: 

1. Choose the Right Potato Variety

Select potato varieties that are well-suited for fall planting and your specific climate. Look for varieties with shorter growing seasons or those labeled as “early” or “second early.”

2. Prepare the Seed Potatoes

  • Chitting: If you have time, “chit” the seed potatoes about 4-6 weeks before planting. This involves placing them in a cool, bright location to encourage sprouting.
  • Cutting: Cut larger seed potatoes into smaller pieces, ensuring each piece has at least 2-3 “eyes” (buds). Allow the cut pieces to dry for a few days to prevent rotting.

3. Prepare the Soil

Choose a location with well-draining soil and at least 6 hours of direct sunlight. Amend the soil with compost or aged manure to improve fertility and drainage.

4. Plant the Potatoes

  • Timing: Plant about 8-10 weeks before the first expected frost in your area.
  • Spacing: Dig trenches or holes about 4-6 inches deep and 12-18 inches apart.
  • Planting: Place the seed potatoes (cut-side down) in the trenches or holes, spacing them about 12 inches apart.
  • Covering: Cover the potatoes with 2-3 inches of soil.

5. Water & Mulch

Water the newly planted potatoes thoroughly and apply a layer of mulch (straw, leaves, or grass clippings) to conserve moisture and suppress weeds.

6. Hill the Potatoes

As the plants grow, gradually “hill” them by mounding soil around the base of the stems. This encourages the development of more tubers.

7. Monitor for Pests & Diseases

Keep an eye out for common potato pests and diseases, such as potato beetles, blight, and scab. Take appropriate measures to control them if necessary.

8. Harvest

Harvest the potatoes when the foliage starts to die back, usually in late fall or early winter, depending on your climate.

Additional Tips

  • Consider using row covers to protect your fall-planted potatoes from frost damage.
  • Monitor soil moisture and water as needed, especially during dry periods.
  • If you experience heavy frost, you might need to harvest your potatoes early to prevent them from freezing in the ground.

So, don’t let the cooler weather deter you. Embrace fall planting for your potatoes and give them the best chance to thrive in the cool soil. With a little planning and effort, you’ll be well on your way to harvesting a bountiful crop of delicious potatoes next season.
