HOW TO GROW CORN, POP
Corn takes about 14 days to emerge from 50°F soils but only about 5 days to emerge at 70°F. Plant about mid May in the Midwestern U.S., as early as mid April in milder climates. Can direct seed as early as mid February with row cover in mild temperate climates. In regions with short growing seasons, start indoors two plants per cell 3-4 weeks before last frost, plant out after frost. Some soak seeds in water tepid for an hour or two before planting. If cool and wet, plant shallow 1 to 1-1/2”. If hot and dry plant 2–3”. Plant in blocks to ensure the best wind pollination. Do not soak seeds before sowing. Open pollinated corn varies more than hybrid corn. Soil pH 5.8-7.0. Hardiness zones 4-8. Annual.
