Best Answer: 65 degrees or higher. Soil temperature that is, not air temperature... Added Info: The below chart taken from Penn State Dept. Of Crop And Soil Sciences website. My suggested temperature of 65 degrees or more, falls in mid-range for optimum seed germination.Also, the type of grass has alot to do with it. Generally, Warm Season grass seed requires the warmer soil temperatures.Even theCool season grass seed likes a warmer soil temperature for successfully germinating... The proof is in the puddin' and that's the truth! Table 1.Optimum temperatures for seed germination of cool-season turfgrasses.oil temperature that is, not air temperature...
