Plant TGI Mirai® Sweet Corn seed in a well prepared seedbed when the soil temperature is above 55° and there is no danger of frost. If you would like to have more than one crop of sweet corn, add a second, third, and possibly fourth planting. When the planted corn begins to peek out of the soil then it is time to plant the next planting.
It’s better to plant the corn in a series of shorter rows, forming a rectangular plot, than one long row. Planting shorter rows will improve pollination and the quality of the corn ears. Corn contains male flowers (the tassels at the top of the stalks), which produce pollen that is blown by wind and falls on to the silk of the female flowers (the ears). In a rectangular plot, the pollen is more likely to reach the silks and less likely to blow away. Rows should be approximately 30 inches apart and seeds spaced about 8 inches in the row. Plant the seed to a shallow depth, no deeper than 1-1/4 inches. Isolate TGF-Mirai® from other corn varieties to prevent cross-pollination, which can change the sweetness and quality of the harvested ears.
Loose soils with neutral pH (5.5 to 7.0) are best. Corn is a heavy feeder, especially of nitrogen. Push the limits of the university recommended fertility in your area. Compost is an excellent addition to your soil. Illinois residents can get more information on fertilizing at the University of Illinois “Watch Your Garden Grow” corn page. In other states, check your local extension office website.
