When to Plant Sweet Corn in Mississippi
In Mississippi, the time to sow sweet corn outside runs from Feb 19 – Mar 5 in Biloxi to Apr 10 – Apr 24 in Oxford. In Jackson, it's Mar 13 – Mar 27. The average last spring frost differs by about 7 weeks across the state (Feb 12 in Biloxi, Apr 3 in Oxford), so use the dates for the town nearest you.
Sow corn in blocks rather than single rows so it pollinates well. Wait for soil around 60°F.
- Sow outside: 1–3 weeks after the last frost.
