If sweet corn seeds are placed in soil that is cool and wet, the seeds have a greatly reduced chance of germination. Any that do sprout will almost certainly exhibit stunted growth. This heat-loving plant prefers air temperatures between 70 and 95 degrees Fahrenheit.f sweet corn seeds are placed in soil that is cool and wet, the seeds have a greatly reduced chance of germination.

Corn will germinate and emerge slowly and unevenly when soil temperatures are less than 50 degrees F. Thermal time from planting to emergence is approximately 115 growing degree days (GDDs) based on air temperature or about 119 GDDs based on soil temperature using the modified growing degree formula (Nielsen, 2008).ogether with soil moisture, the temperature determines the ideal planting time for many Michigan crops. The minimum threshold temperature for corn seed germination is 50 degrees F in the seed zone.
