You should fertilize corn when planting and late in the growing season. More Info: Assuming the soil pH is unknown, when initially planting corn till into 100 square feet of soil 3-4 pounds of a commercial fertilizer such as 12-12-12. As soon as the plant has reached a height of 16-18â high side dress the plant with additional fertilizer at a rate of one tablespoon per hill. Fertilize the soil not the plant and water deeply. The best way to tell exactly how much fertilizer and/or soil amendments you will need is to have your soil tested.
(Corn will not germinate if soil temperature is less than 55 F.) To speed increase in soil temperature, consider covering soil with black plastic for several weeks before planting. Plant in blocks of at least 4 rows of a single hybrid (as opposed to fewer, longer rows) for good pollination and well-filled ears. (Some corn varieties need to be isolated from others. See variety information below.) Plant seeds 1 inch deep and 4 to 6 inches apart in rows 30 to 36 inches apart.
