When to Plant Potatoes in Arkansas (2026 Guide)
Growing potatoes in Arkansas can be a rewarding endeavor for any home gardener. With the right timing, you can enjoy a plentiful harvest of this versatile crop. It’s essential to understand the local climate and frost dates specific to your area, as these factors significantly impact your planting and harvesting schedules. For instance, in Zone 7a, the median last spring frost occurs on March 29, allowing an extended growing season.
Potatoes thrive in the cool soil typical of early spring, making them suitable for planting even while temperatures might still dip at night. Planning to plant in early spring ensures that you can take full advantage of the frost-free season, which can be around 221 days in Zone 7a. Cities like Little Rock and Conway provide an ideal environment for potatoes, given their climate variations and prolonged growing days.
Understanding the growth cycle of potatoes is critical to maximizing your yield. They generally take 70 to 120 days to mature based on the variety selected. By managing frost dates effectively, such as utilizing the last frost date of April 7 in locations like Batesville (Zone 6b), you can ensure a successful growth period leading up to your harvest in late summer or early fall.
Planting Schedule by USDA Zone in Arkansas
| Zone | Indoor start | Transplant out | Direct sow | Harvest |
|---|---|---|---|---|
| Zone 6b | Start February 15 – March 1, ~6–8 weeks before April 7 | Transplant outdoors from March 29 – April 7, after the last spring frost | Direct sow from March 29 – April 7, after the last frost | Harvest from August 25 – October 1, after sufficient skin-setting |
| Zone 7a | Start February 20 – March 5, ~6–8 weeks before March 29 | Transplant outdoors from March 15 – March 29, before the last spring frost | Direct sow from March 15 – March 29, before the last frost | Harvest from August 15 – September 30 for optimal yield |
| Zone 6a | Start March 1 – March 15, ~6–8 weeks before April 16 | Transplant outdoors from April 7 – April 16, after the last spring frost | Direct sow from April 7 – April 16, after the last frost | Harvest from August 15 – September 30, after the foliage has died back |

Common Mistakes Growing Potatoes in Arkansas
- One common mistake gardeners make in Arkansas is planting too late in the spring. With frost dates varying by zone, like April 7 in Zone 6b, planting after this date can jeopardize yields significantly as potatoes require a certain cool temperature to develop properly.
- Another mistake is using grocery store potatoes as seed. In Arkansas, where diseases like potato virus Y can be prevalent, using certified disease-free seed potatoes is essential to prevent crop failure and ensure a healthy harvest.
- Gardeners often overlook the significance of soil conditions. Arkansas's clay soil needs proper drainage to prevent rotting tubers. Incorporating organic matter can improve soil structure and promote healthy growth for potatoes, especially in wetter spring months.
- Inconsistent hilling is a frequent error. Failing to hill potatoes appropriately throughout the growing season can reduce tuber yields and expose them to greening. Hill potatoes about 2–3 times as they grow to promote better yields and prevent bitterness.
- Finally, many consider the length of the growing season enough to rush the harvest. Properly assessing when the tops die back is crucial, which is around 2–3 weeks after foliage turns yellow in Arkansas, to ensure skin setting and storage quality.
Frequently Asked Questions
What if I'm in a cold pocket of Arkansas?
If you're located in a colder area, consider starting the potatoes indoors earlier and pay close attention to frost dates. You still want to transplant after the last spring frost date, which may be later in your region.
Can I still plant potatoes in May?
Planting in May can be risky due to rising temperatures and shorter growth periods before fall frosts. If you're in Zone 7a, aim to plant by late April for the best chance of a successful harvest.
How can I tell when to harvest my potatoes?
You can identify when potatoes are ready to harvest by observing the foliage. When the leaves start to yellow and die back, it’s time to check. Letting them sit for another couple of weeks improves skin quality.
What is the best choice of variety for Arkansas?
In Arkansas, consider early varieties like Red Bliss or Yukon Gold for shorter growing seasons. For longer seasons, starchy varieties like Russets can be ideal. Selecting based on your specific zone will help optimize yields.
How should I store my harvested potatoes?
After harvesting, allow your potatoes to cure in a dark, humid space for about 10-14 days. Once cured, store them in a cool, dark location at around 38-45°F with good air circulation for up to 5 months.
