When to Plant Sweet Corn in Kentucky
In Kentucky, the time to sow sweet corn outside runs from Apr 7 – Apr 21 in Shively to May 8 – May 22 in Shelbyville. In Louisville/Jefferson County metro government, it's Apr 13 – Apr 27. The average last spring frost differs by about 4 weeks across the state (Mar 31 in Shively, May 1 in Shelbyville), 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.
