Prepare soil for planting corn when all threat of frost is past. In Texas, this can be anywhere from late March to late April. Turn the soil with a rototiller, cultivating to a depth of 12 inches, removing rocks and old vegetation as you go.
Spread 10-10-10 fertilizer evenly over the soil at a rate of 2 to 3 lbs. per 100 square feet. Till again to a depth of 4 inches, and rake smooth. Water with an inch of water.
Pull the tip of a hoe through the soil to create rows that are 2 inches deep. Space rows 3 feet apart.
Set seeds in the rows at a depth of 2 inches, 12 inches apart. Cover with soil, pat the soil down firmly and water with another inch of water. Seeds will germinate and sprout within 7 to 10 days.
