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.
Fescue just needs, full sunlight, proper fertilization, some rain, and to be mowed at the optimum height (3.5 inches) to be a vigorous competitor against any weed. Too often I talk with homeowners that want to grow grass where there is heavy shade. Shade and grass donât mix.
