Growing Sweet Potatoes in Northern Minnesota: Slips, Timing, and Deer Resistance

Sweet potatoes are grown from slips (rooted sprouts), not seed tubers. Start slips indoors 6–8 weeks before last frost, or purchase certified slips.

Northern Growing Tips

• Choose 90–100 day varieties ('Beauregard', 'Georgia Jet').
• Plant after soil reaches 65°F (early June in MN).
• Use black plastic mulch to warm soil and suppress weeds.
• Space slips 12–18" apart in rows 3 feet apart.

Deer Resistance

Sweet potato vines are less appealing to deer than many crops, but young slips may be browsed. Protect with row covers or a temporary fence until established.

Harvest before first frost; cure 10 days at 80–85°F for sweetness and storage.
