Now, most germination failure (especially with warm season grass) is because the grass seed was planted too early. Grass seeds have an outer shell (the hull) that prevents germination until conditions are right. Proper soil temperature is a big factor in the success youâll have. For cool season grass, the ideal soil temperature is a minimum of 45-55 degrees (F). For warm season grass, the ideal soil temperature is a minimum of 55-65 degrees (F).
Soil temperature is an important factor in seed germination and emergence. Together 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.orn 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).
