Corn plants are wind pollinating plants, so it is essential to plant a minimum of four side-by-side rows to ensure robust pollination. It is also best to rotate where you plant your crop each year to prevent disease, pest issues, and nutrient depletion from occurring. Sweet corn is a temperature-sensitive crop that should be planted only after the soil warms, and the danger of frost has passed.
Start with fresh corn seeds for the best results.
Directly sow seeds approximately 1.5 to 2 inches deep and 4 to 6 inches apart.
Cover with soil, space your rows of seeds 30 to 36 inches apart.
Water your block of corn well after planting.
Corn stalks are sturdy and should not need staking.
Maintain your garden bed of corn by lightly hoeing the soil just below the surface to aerate the soil and remove weeds. As heavy feeding plants, corn cannot compete with weeds. It is important to avoid deep soil penetration, which can sever the shallow growing roots of the corn.
You can start harvesting the corn when the husks turn dark green and the silky tops become dry and brown, and the kernels become full-sized.
