Managing Bermuda Grass Invasion in Tall Fescue Lawns

Bermuda grass creeping into a tall fescue lawn in Georgia is a classic warm-season vs. cool-season conflict. Bermuda turns brown in winter, looks thin and straggly, and spreads aggressively via rhizomes and stolons.

Solarization—covering infested areas with clear plastic during hot weather—can kill Bermuda organically by superheating the soil. Do this as Bermuda enters dormancy, then reseed fescue. It's an annual battle, but consistent effort keeps fescue dominant.

If you decide to embrace Bermuda, choose an improved cultivar like 'Tifway 419' or 'Celebration' for better density, color, and cold tolerance. Mow at 1–1.5 inches, fertilize lightly in summer, and accept winter dormancy.

Molasses alone won't control Bermuda; the plastic smothering effect does the work. There's no selective herbicide that kills Bermuda without harming fescue, so physical removal and cultural management are your main tools.
