Controlling Nutsedge (Nutgrass) in the Lawn

Nutsedge (often called nutgrass) is a persistent, fast-growing sedge—not a true grass—that outpaces regular mowing. It requires targeted herbicide treatment.

Herbicide Options

• MSMA-containing products (Basagran, Manage/Sedgehammer): Reduce populations significantly with repeated applications. Won't fully eradicate but provide control.
• Glyphosate (Roundup): Spot-treat for small infestations, then reseed. Only provides one season of relief without ongoing program.

Long-Term Management

Nutsedge tubers persist deep in soil. A multi-year program combining herbicides, improved drainage, dense turf competition, and proper mowing height is essential. Expect bare spots after treatment that require reseeding.
