Growing Sweet Potatoes in Zone 2A

Sweet potatoes need heat and a long season but are incredibly productive and nutritious.

Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Grow from slips (sprouts), not seed — order or start your own
• Needs 90-120 frost-free days with warm soil
• Black plastic mulch warms soil in cooler zones
• Harvest before first frost — cold damages tubers
• Cure at 80-85°F for 10 days for sweetest flavor and best storage

Companion Planting

Good companions: beans, corn, thyme

Avoid planting near: squash (compete for space)
