Dormant seeding for warm-season grasses occurs in early fall as they require 65 °F and above sustained soil temperatures and moisture to germinate. Cool-season grasses will germinate at colder temperatures, a soil temperature at a depth of 1” at or below 40 °F. Cool-season grasses generally germinate in a shorter period of time.
