How to Grow Sweet Corn Commercially

Find a healthy location to plant the kernel seeds. Areas that have had beans grown in them the previous year have richer soil because of the nitrogen and moisture that they left behind.

Commercially grown sweet corn can only grow in rich soil. Use a quality soil fertilizer or aged manure to add in extra nutrients to the soil.

Plant two or three seeds 12 to 15 inches apart from each other, and in rows 30 to 36 inches apart. Plant the corn seeds in blocks instead of planting them in long, single rows, which is essential to preventing poor pollen distribution. Plant sweet corn seeds 1.5 inches deep.

Moisture is imperative to the growth of sweet corn. After planting, be sure to water daily so that the plant can form tassels, silks and ears. Water rows more frequently as temperature warms. Use the hoe to maintain a clean garden in and around rows, freeing up excessive weed growth.

Harvest your commercially-grown sweet corn if kernels are filled out and tightly packed. Check to see if corn is fully developed by puncturing a stalk with a thumbnail--a milky substance should appear, signaling its readiness.

Properly harvest sweet corn by bending the stalk down and pulling it toward the ground in a twisting fashion. Package sweet corn properly. Freezing or refrigerating can retain its taste best upon harvesting.
