How to Grow Sweet Corn From Seed


Sweet corn is prized for its taste and tenderness. Most gardeners plant sweet corn every year in their gardens. It is available in several varieties including normal, sugar-enhanced and super-sweet. Color varies as well, with differing proportions of yellow and white. Ample space in the garden is needed but it's well worth it.

Step 1

Prepare the soil by removing all grass, rocks and debris. Till organic fertilizer such as cow manure into the soil.

Step 2

Follow all instructions on seed packages for planting times in your area. Corn is harvested approximately 60 days from planting so make sure the soil is above 50 degrees and the area receives full sun.

Step 3

Form rows in the soil by mounding the soil up approximately 3-5 inches and as long as you desire. Keep the rows 30-36 inches apart. Make more than one row as corn cross-pollinates and needs stalks nearby.

Step 4

Plant two or three seeds every 12-15 inches in the top of the rows and 1 to 1 1/2 inches deep. The space is necessary, as the stalks grow large and tall.

Step 5

Water the new seeds well and keep the soil moist. Corn requires a lot of water to produce the sweet juiciness of good corn. If more than one corn stalk is growing in the same spot, pull the smaller of the two, leaving one growing only. Make sure you keep all weeds and grasses from growing around the corn by pulling the weeds or hoeing.

Step 6

Fertilize the plants again when the stalks are approximately 15-18 inches high, with organic fertilizer. Use an organic pest spray to keep worms from eating the top of the corncobs.

Step 7

Corn is ready to harvest approximately 3 weeks after the silk has formed. To remove the corn, grasp the cob firmly at the base of the cob and pull downward and twisting at the same time to break the cob from the stalk. Pull the leaves and silk from the cob, rinse well, cut off any bad ends and cook as desired.
