When to Plant Potatoes in Oklahoma

Incredibly satisfying to grow. There's nothing quite like digging up your own potatoes — it's like buried treasure.

The Short Answer

In Oklahoma, soil conditions are an important factor for potatoes. Red clay soils common. Alkaline in west. Rich prairie soils in east. Wind erosion in western panhandle. Direct sow 2 weeks before your last frost date.

Growing Potatoes in Oklahoma

Potatoes in Oklahoma's Climate

Potatoes are a cool-season crop in warm climates — plant in late winter for late spring harvest before summer heat shuts tuber growth down. Once soil temperatures exceed 85°F consistently, tuber growth stops. Choose heat-tolerant varieties like Red LaSoda. Some southern growers plant a second crop in August for fall harvest.

Soil Considerations for Oklahoma

Red clay soils common. Alkaline in west. Rich prairie soils in east. Wind erosion in western panhandle. Loose, well-drained soil is especially important for potatoes since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Oklahoma Climate & Growing Season

Hot summers. Severe thunderstorms and tornado risk. Good growing season length. Windy — windbreaks help gardens.

Growing season length varies across Oklahoma: Northern Oklahoma (6b, 7a) has a last frost around Apr 5 - Apr 20, while Southern Oklahoma (7b) sees frost end around Mar 15 - Apr 1. This difference matters for potatoes — adjust your planting dates to match your specific region.

Growing Tips

Plant seed potatoes (not grocery store potatoes) 2-3 weeks before last frost. Hill soil around stems as they grow to increase yield.

Companion Planting

Plant potatoes alongside these companions for better growth:

Beans Corn Cabbage Marigolds

Keep potatoes away from:

Tomatoes Squash Sunflowers

The Bottom Line

Potatoes can be grown successfully across Oklahoma, but your exact planting dates depend on which region you're in. Northern Oklahoma gardeners should plan around a Apr 5 - Apr 20 last frost, while those in Southern Oklahoma can typically plant earlier.
