White Corn Seeds

WHEN TO PLANT CORN Plant seeds outdoors approximately two weeks after the last spring frost date. Consult our Planting Calendar (above) to see suggested planting dates for your region. It’s important to get corn planted as soon as possible, since it requires a fairly long growing period with warm weather. If you live in an area with a shorter growing season, choose an early variety that will mature well before the first fall frost. Make sure the soil temperature is above 60°F (16°C) for successful germination. (Up to 65°F/18°C for super sweet varieties.) In colder zones, the ground can be warmed by a black plastic cover, if necessary. Plant seeds through holes in the plastic. A couple weeks after planting your first round of corn, plant another crop to extend the harvest.
