Corn Seed Starting Tips

For early plantings, sow seeds only 1 inch deep; in the hot weather of midsummer, plant them up to 2 inches deep. The average germination rate for sweet corn is about 75 percent, so plant three seeds together every 7 to 15 inches. They should germinate in 7 to 10 days. Thin to one plant every 15 inches.

Should you soak corn seeds before planting?

Soak Corn Seeds

Sweet corn seeds can appear shrunken and shriveled; before they can germinate, they must slowly plump up with water. To help them along, soak dry seeds in water at room temperature overnight before planting.

Can you start corn seeds indoors?

Starting Corn Indoors

Approximately four or five weeks before the last frost is the ideal time to sow corn seeds indoors. Fill sterilized containers with seed-starting mix and sow one or two seeds in each cell at a depth of 1 inch. Water regularly to keep the soil moist.

How do you prepare a field for planting corn?

Leave crop residues on the surface, kill weeds with herbicide, till with sweep or chisel, then light disking, or use rotary tiller for entire operation; seed is planted with regular planter with disk openers or furrow openers on shoe-type planter. Conserves moisture, reduces runoff.

What month do you plant corn?

Corn is a warm-season annual that is best planted after the soil temperature reaches 60°F (16°C), usually two or three weeks after the last frost in spring. Corn planted in cold, wet soil is unlikely to germinate.

How long do you soak corn seeds before planting?

When soaking corn seeds, use lukewarm water, about 68 F, and if you're planting more than one variety of corn, soak them in separate labeled containers. Recommended soaking times range from a few hours to up to 24 hours, with no more than eight hours being the usual.

How do you start seeds from egg cartons?

You can use egg cartons as a seed-starting tray! Depending on the type of carton you have, you can even cut apart the individual sections and plant them, as the carton will biodegrade. Be sure to poke small holes for drainage, and put the cartons on a tray or in a shallow pan to catch any residual water.

What happens if you plant a seed upside down?

Whether a seed is sown upside down, right side up or on its side, it has the ability to position itself so stems grow upward and roots grow downward. Seeds contain growth hormones that respond to gravity and rotate the seed to the correct orientation.

How long does it take for a corn seed to sprout?

At 50° F corn will take approximately 25 days to emerge. At 55-60° F corn will take 10-14 days to emerge. At 65-70° F corn only takes five to eight days to emerge ⁽^Meyer⁾. How long a seed can last in the soil and remain viable depends on temperature, moisture, and pests.

How do you speed up seed germination?

Some place a baking sheet with a dish towel on top above the warm surface and place the seed starting tray on top. Even with just a couple of hours of slow heat, some seeds respond quickly (within a day or two) to added warmth.

Can you grow corn from a corn cob?
