When to plant Sweet Potato
Sweet potatoes are a warm-season crop. Plant slips well after the last spring frost, once the soil has warmed above 65F; never rush them into cold ground (Clemson).
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
