Plant after the soil has warmed to around 55 to 60 degrees Fahrenheit or just after the average last frost date.
Hoe the planting area into rows 30 to 36 inches apart. Make the furrows 1/2-inch deep for cool moist soils and 1-1/2 inches deep for warm dry soils.
Plant the corn seeds 9 to 12 inches apart along each furrowed row. Cover over the seeds with soil and gently pack the soil down by hand.
Water the planted rows of corn with a watering can until the soil is evenly moist. Keep the soil moist throughout the growing season. Corn requires approximately 1 inch of water per week. Use a watering can to supplement in between rainfalls to keep the corn watered.
