Plant fescues when fall temperature reach about 75 F. The next best time to plant fescue seeds is when rising temperatures in spring reach 60 F. Summer isn't a good time to plant fescue lawns, because fescue grass tends to go dormant during periods of high temperature.
It does need some sun, and will not grow in total shade. Fall is the best time for seeding fescue. Oklahoma is in a transition zone â too hot for cool-season grasses and too cold for warm-season grasses. Bermuda grass is rarely seeded in our zone, but rather established by sod or sprigs.
