Centipede vs. Tall Fescue: Why Centipede Wins and How to Switch

The Verdict

In a mixed lawn, centipede grass will choke out tall fescue. It’s more aggressive in warm climates like North Carolina. Overseeding fescue into centipede won’t work—centipede dominates.

The Fix: Remove Centipede, Then Reseed Fescue

1. Buy professional-grade glyphosate: Go to a landscape supply dealer (Helena, Southern Ag) for Round-Up Pro (41% active ingredient). Box-store versions are only 18%.
2. Spray centipede areas: Follow mixing instructions precisely. Wait 2 weeks for complete kill. Re-spray any green survivors.
3. Reseed with quality tall fescue: Once centipede is dead (no green left), sow a premium tall fescue blend.

Cost and Payoff

Average lawn: $100–150 for herbicide and seed. The result—a uniform, wear-tolerant fescue lawn that handles dogs, kids, and foot traffic—is worth every penny and hour.

Why Not Just Overseed?

Centipede’s dense, low growth shades out fescue seedlings. Fescue can’t establish. You must eliminate the competition first.
