Overview
Dent and flint corns are the grain corns that sustained Appalachian families for generations—dent for cornmeal, grits, and animal feed; flint for polenta, hominy, and posole. Unlike sweet corn eaten fresh, these corns are harvested dry on the cob and stored for year-round use. A single acre of dent corn produces 80–120 bushels of grain—enough to feed a family and their livestock through winter.
Dent corn gets its name from the characteristic dent in the crown of each kernel as it dries. It's the standard cornmeal corn of the South—white and yellow varieties make the cornbread, hushpuppies, and spoonbread that define Appalachian cuisine. Flint corn has harder, glassy kernels with more protein and less starch, making it preferred for polenta, hominy (nixtamalized corn), and traditional mush.
In Zone 6b/7a, plant grain corn after soil reaches 60°F—typically mid-May. Open-pollinated heirloom varieties allow seed saving, unlike hybrid field corn. Save seed from the best ears of the strongest plants each year to adapt varieties to your specific WV microclimate over time.
Type: Annual Grass • Family: Poaceae • Sun: Full Sun • Water: Moderate to High • Soil pH: 5.5–7.0 • Hardiness: Annual (all zones)
Zone 6b/7a Planting Calendar
Indoor Start: N/A (direct sow only—corn doesn't transplant) • Direct Sow: Mid-May after soil 60°F; plant 1 inch deep, 8–12 inches apart in rows 30–36 inches • Transplant: N/A • Harvest: September–October (when husks dry brown and kernels resist thumbnail pressure)
Growing Conditions
Soil: Heavy feeder—requires deep, rich, well-drained loam with plenty of organic matter. Follow nitrogen-fixing cover crop.
Fertilizer: Very heavy feeder. 2–3 inches compost + balanced organic fertilizer at planting. Side-dress with blood meal at knee-high. Fish emulsion during rapid growth.
Companions: Beans and squash (Three Sisters), sunflowers, amaranth, cucumbers, melons
Avoid: Tomatoes (shared pests), fennel (inhibits growth), pole beans (unless Three Sisters)
Pests & Diseases
Corn earworm (inevitable in organics—trim damaged tips). European corn borer. Fall armyworm. Raccoons (primary threat at harvest—electric fence or dogs). Birds pull seedlings. Corn smut (huitlacoche—is actually a delicacy).
