Corn Planting Time. Corn is a tender, warm-season annual that is best planted after the soil temperature reaches 60°F, usually 2 or 3 weeks after the last frost in spring. Corn requires 60 to 100 frost-free days to reach harvest depending upon variety and the amount of heat during the growing season. Corn grows best in air temperatures from 60° to 95°F. Corn planted in cold, wet soil is unlikely to germinate. Corn seed germinates in 10 to 14 days at 75°F, but the rate of germination may reach only 75 percent. Start corn indoors 2 to 3 weeks before the last frost in spring for transplanting 2 to 3 weeks after the last frost. If your season is long enough, plant successive crops every two to three weeks.
For live plants, we can't send them to Alaska and Hawaii. If the order has already been placed, we will cancel it.
Happy Gardening!
