Controlling Bermuda Invasion in Fescue: A Difficult Challenge

The Core Problem

Bermuda and fescue are both grasses—selective herbicides that kill Bermuda also kill fescue. No chemical solution exists that spares fescue.

Management Options

• Accept a mix: Some lawns transition to Bermuda in sun, fescue in shade.
• Spot-treat with non-selective (glyphosate) and reseed fescue: Labor-intensive, repeated.
• Solarize: Clear plastic in summer heat kills Bermuda rhizomes in top 6–8 inches. Reseed fescue in fall.
• Shade encouragement: Fescue tolerates shade; Bermuda doesn't. Overseed fescue in shady areas.

Best Advice

Consult local nurserymen in SE Tennessee. They know regional conditions and may have access to newer suppression techniques. Complete eradication without harming fescue is nearly impossible.
