Growing Sweet Potatoes in Southern Minnesota: Is It Possible?

Climate Challenges

Sweet potatoes require a long, warm growing season (90–120 frost-free days) and soil temperatures consistently above 65°F. Southern Minnesota's shorter season makes this difficult but not impossible with careful planning.

Strategies for Success

• Start slips indoors 6–8 weeks before last frost.
• Use black plastic mulch to warm soil early.
• Choose short-season varieties like 'Beauregard' or 'Georgia Jet' (90–100 days).
• Plant in raised beds for better drainage and warmth.
• Harvest before first fall frost—cold damages roots.

Realistic Expectations

Yields will be smaller than in southern climates. Consider sweet potatoes a fun experiment rather than a staple crop. Alternatively, grow them in large containers that can be moved to protected spots.
