When to Plant Sweet Corn in Texas
In Texas, the time to sow sweet corn outside runs from Jan 16 – Jan 30 in Brownsville to Apr 22 – May 6 in Amarillo. In Houston, it's Feb 9 – Feb 23. The average last spring frost differs by about 14 weeks across the state (Jan 9 in Brownsville, Apr 15 in Amarillo), 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.
