Zea mays## HOW TO GROW CORN, SWEET Sweet corn takes about 14 days to emerge from 50°F soils but only about 5 days to emerge at 70°F. Direct sow in mid May in the Midwestern U.S., in mid April in milder climates. Direct sow as early as mid February with row cover in mild temperate climates. In regions with short growing seasons, start indoors two plants per cell 2-4 weeks before last frost, plant out 0–2 weeks 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 hybrids. Soil pH 5.8-7.0. Hardiness zones 4-8. Annual.Days from maturity calculated from the date of seeding.
