How to get rid of nutsedge?

Controlling Nutsedge in Charlotte Lawns

Nutsedge (nutgrass) is a challenging lawn pest, particularly problematic in Charlotte's humid climate. This sedge grows faster than grass, creating distinctive three-cornered stems and yellowish-green appearance. Underground nutlets make control persistent—one season of treatment typically requires follow-up management.

Identification and Growth Cycle

Nutsedge appears in early summer and grows aggressively through fall. It's more visible and vigorous than desirable grass. Notice three-cornered stem (not round like grass) and glossy appearance. Each plant produces numerous small tubers (nutlets) underground that survive herbicide treatments, creating perennial problems.

Control Strategies

• Selective Herbicides: Sedge-specific products containing halosulfuron or sulfosulfuron effectively kill nutsedge without harming grass. Apply mid-to-late summer when plants are actively growing
• Manual Removal: Dig plants including tubers before flowering. Incomplete removal leaves viable tubers for regrowth
• Repeated Treatments: Expect 2-3 applications spaced 7-10 days apart for complete kill due to tuber protection
• Containment: In localized infestations, containment through repeated pulling prevents spread while awaiting chemical treatment timing

Prevention and Long-Term Management

Maintain dense, healthy grass through proper fertilization and watering. Nutsedge struggles where grass is competitive. Address moisture issues—nutsedge prefers wet soils. Improve drainage through aeration where moisture is excessive. Monitor for new shoots throughout summer and treat promptly before tuber production.
