what temperature does the ground have to be for grass to grow
PLANT WHEN DAYTIME TEMPERATURES ARE BETWEEN 60 & 75 DEGREES: Cool season grasses grow best when the soil temperatures are between 50 and 65 degrees F. These temperatures usually occur when the daytime air temperatures are between 60 and 75 degrees. High temperatures of summer can cause these plants to go dormant and thus planting during summer is asking for problems.
