Best approach: Herbicide spray

DO NOT pull nutsedge — pulling stimulates underground tubers to produce more plants, making the problem worse. Always use a sedge-specific herbicide like SedgeHammer.

Chemical treatment

Apply a sedge-specific herbicide (halosulfuron/SedgeHammer or sulfosulfuron) when plants are actively growing in late spring through summer. Multiple applications over the season are usually needed.

Non-chemical management

Improve drainage and reduce irrigation. Hand-pulling is ineffective due to underground tubers; rely on herbicides.

How to stop Nutsedge coming back

Avoid waterlogged conditions — nutsedge thrives in wet soils. Improve drainage and don't overwater.
