What soil temperature range is best for seed germination and the growth of turfgrass species?
Soil temperature greatly influences many activities and reactions that take place in the soil. Seed germination is no exception. There is a distinct temperature range in which optimum turfgrass germination and growth occur. The optimum range for germination and growth of cool season turfgrasses (such as Tall Fescue) is approximately 65+ degrees. The optimum temperatures for the growth of warm season grasses like bermudas are between 70 and 95 degrees.
