Modern corn is the product of thousands of years of specialized cultivation. It originated as a wild grass in Central America. Through selective breeding, it evolved into the plant we are familiar with today. Corn is now grown throughout much of the United States and has dozens of uses, from a food source to cat litter. The ease of growth and versatility of corn make it a perfect addition to any home garden.
Check the soil temperature with a soil thermometer beginning in mid-May. Corn is safe to plant once the temperature is between 50 and 60 degrees at a depth of 5 inches.
Prepare the planting site in an open, sunny area. Add a 1-inch layer of compost to the top of the soil and mix it with the top 2 inches of soil, using a hoe. Keep in mind the corn should be arranged in a series of rows that make a block rather than one long row.
Plant three corn seeds in a hole at a depth of 1 inch. Plant three more corn seeds approximately 12 inches away. Repeat this until you reach the end of the row.
Plant each additional row 30 to 36 inches apart from one another.
Water the soil so it is thoroughly wet, but not soggy. Keep the soil wet at all times throughout the growth cycle.
Thin out the weaker plants once they grow to 3 inches if more than one seed germinates in a single spot. To do this, simply pull the plant straight out of the ground and discard it.
Fertilize the corn with a nitrogen-rich fertilizer once the stalks reach 12 inches.
Watch for tassels to grow from the ends of the ears. The corn can be harvested three weeks after this occurs.
