Figure 1. Corn growth and temperature levels. Corn will germinate and grow slowly at about 50 F (10 C), but the average first spring planting dates across the U.S. usually begin when the average air temperatures reach 55 F (13 C) and soil temperature at seed depth is favorable for seedling growth.
Whether you wish to grow sweet corn, popcorn, novelty-colored corn varieties or field corn, providing corn seeds with the appropriate temperature and moisture conditions will greatly improve their germination rate.nce garden soil has reached a temperature of least 65 degrees F, soak corn seeds in tepid water for approximately an hour. Plant seeds outdoors in prepared garden soil. If your soil is heavy, with lots of organic matter, plant seeds about 1 inch deep. If your soil is sandy, plant seeds about 2 inches deep.
