Answer: Corn requires full sun and a rich loam soil with a pH of 5.5 to 6.8. Plant the seeds about 4 inches apart in the row, with rows from 24 to 36" apart. The plants are then thinned to about 8" apart. Corn is a heavy feeder. Even if you have rich soil, and have worked in compost or manure, you still may want to fertilize during the growing season. Some growers spread superphosphate before tilling. Plan to fertilize when the plants are about 6" tall with a fertilizer containing nitrogen, and then feed again every week or two until you see the silks forming. You can use anorganic fertilizer like fish emulsion, or a balanced commercial fertilizer.
