How to Plant and Grow Sweet Corn
Direct sow 5-6 seeds per foot, about 1-2 in. deep in rows (a minimum of 4 rows will ensure pollination) 3 ft. apart. Thin to 12 in. apart. Kept at 70-90°F., germination is in 7-14 days. If birds are a problem, sow in cell packs and transplant into the garden 1 ft. apart. Planting is done from spring through early summer, beginning after all danger of frost, and when the ground has warmed. Make 3 or 4 additional plantings at two week intervals to extend the season. Do not plant near popcorn. When the kernels ooze a milky juice when pierced, they are ready to harvest.
