When to Plant Sweet Corn in Louisiana
In Louisiana, the time to sow sweet corn outside runs from Jan 29 – Feb 12 in New Orleans to Mar 24 – Apr 7 in Minden. In New Orleans, it's Jan 29 – Feb 12. The average last spring frost differs by about 8 weeks across the state (Jan 22 in New Orleans, Mar 17 in Minden), 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.
