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.
Fresh sweet corn can be worth the wait. Gardeners usually plant corn (Zea mays) 10 days to two weeks after the last spring frost, when the soil temperature begins to warm. If corn is planted when the soil temperature is 60 F, then corn sprouts typically break the soil surface in 10 days to two weeks. If you planted sweet corn and two weeks passed without sight of the first green shoot, then several factors may have caused the delay.
