Corn is a hardy summer crop that will pollinate itself. Sweet corn varieties typically are planted in home gardens, according to the University of Tennessee Agricultural Extension Service, because they have more taste than bland field corn. There are several hundred varieties of sweet and supersweet corn to choose from. Meeting corn's growing needs and spacing requirements allows you to enjoy a healthy harvest in the fall.
Things You'll Need
Soil thermometer
Spade
12-12-12 fertilizer
Choose a moist, fertile, well-draining location with access to full sun. Corn requires full sunlight.
Measure the soil temperature with a thermometer. It should be reliably at 50 degrees Fahrenheit before you plant.
Use a spade to break up the soil to a depth of 6 inches. Break up any large clods so the corn will have an easier time pushing its roots through the earth.
Apply between 3 and 4 lbs. of a 12-12-12 fertilizer for every 100 square feet of soil.
Plant kernels in rows that are between 36 and 42 inches apart, spacing the kernels between 10 and 15 inches apart. This spacing prevents the plants from crowding each other.
Vary the planting depth based on what kind of soil you have. In cool, moist soil, plant the seeds about ? inch deep. In warm, drier soil, plant the kernels between 1 and 1? inches deep.
Cover the kernels lightly with soil.
Water thoroughly.
Tips & Warnings
If space is short, plant the corn in double rows, which are about 10 inches apart, with between 30 and 36 inches of spacing between the double rows.
Do not plant sweet corn next to field corn, as cross-pollination affects the taste.
