When to Plant Sweet Corn in Alabama
In Alabama, the time to sow sweet corn outside runs from Feb 28 – Mar 14 in Mobile to Apr 11 – Apr 25 in Trussville. In Huntsville, it's Mar 31 – Apr 14. The average last spring frost differs by about 6 weeks across the state (Feb 21 in Mobile, Apr 4 in Trussville), 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.
