When to Plant Sweet Potatoes in Arkansas

Not related to regular potatoes at all. Sweet potatoes need heat and a long growing season but reward with incredible harvests.

Growing Sweet Potatoes in Arkansas

Sweet Potatoes in Arkansas's Climate

Sweet potatoes thrive in your climate. The long, warm growing season gives them all the time and heat they need. Plant slips from April and enjoy one of the easiest, most productive crops available in warm zones. Sweet potatoes are remarkably drought-tolerant once established — they handle dry spells better than most vegetables.

Soil Considerations for Arkansas

Heavy clay in lowlands. Rocky soil in Ozarks. Raised beds recommended for drainage. Loose, well-drained soil is especially important for sweet potatoes since the edible portion grows underground. If your soil is heavy clay, consider raised beds.

Arkansas Climate & Growing Season

Hot, humid summers. Moderate winters. Good growing conditions for most vegetables. Sweet Potatoes cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.

Growing season length varies across Arkansas: Northern Arkansas (6b, 7a) has a last frost around Apr 5 - Apr 20, while Southern Arkansas (7b, 8a) sees frost end around Mar 15 - Apr 1. This difference matters for sweet potatoes — transplant timing shifts by several weeks across the state.

Growing Tips

Grow from slips, not seeds. Start slips from a sweet potato in water 8 weeks before transplanting. Cure harvested tubers in warmth for 10 days.

Companion Planting

Plant sweet potatoes alongside these companions for better growth:

Beans Corn

Keep sweet potatoes away from:

Squash

The Bottom Line

Sweet Potatoes can be grown successfully across Arkansas, but your exact planting dates depend on which region you're in.
