Corn requires rich,
well-drained soil with a pH of 6.0 to 6.8., full
sunlight and one inch inch of water every week. Avoid watering from above, as it will wash away the pollen.
Fertilize with 1/2 strength nitrogen fertilizer and
foliar feed the plants with a balanced
fertilizer when they are 8 to 16

seeds 1 to 2 weeks after the last frost, when the soil
temperature reaches 55 to 60 deg F. Treat the seeds with
seed treatment prior to planting. Plant field corn in
40-inch rows with plants spaced 15 inches apart. Plant
sweet corn with 6 to 8 inches between plants and 25 to
30 inches between rows. Plant popcorn and ornamental

depth will depend on the time of year and available
moisture . Early in the season, plant sweet corn at
1-1/2 inches and field corn at two inches. As the soil
warms up and moisture decreases, plant a little deeper.
Late plantings of sweet corn should be made three to
four inches deep. Weeds can be a
problem almost immediately after planting. Mulch between
the rows right after planting to reduce weeds growth.
Mulch between plants when they reach 6 to 8 inches
