Tips & Best Practices
- Plant slips (rooted sprouts) 3–4 weeks after the last frost when soil is 70°F+.
- Sweet potatoes need a long, hot season — at least 100 warm days.
- Grow in raised beds or mounds for best drainage and warmth.
- Cure harvested sweet potatoes at 80–85°F for 10 days before storing.
