If you have bright green, fast-growing patches that outpace your turf and survive regular weed killers, you’re likely dealing with nutsedge.

SedgeHammer® Plus is specifically formulated to control yellow and purple nutsedge without harming established turfgrass when used as directed.


Why SedgeHammer Works

  • Systemic action moves through the plant to control sedge at the root and tuber level
  • Selective control that is safe on most cool- and warm-season turfgrasses
  • Effective on actively growing nutsedge

Unlike common broadleaf herbicides, SedgeHammer targets sedges specifically.


When to Apply

  • Apply to actively growing nutsedge
  • Best results when sedge is young and not drought-stressed
  • Avoid mowing 2 days before or after application

Visible yellowing may begin within 7–14 days. Complete control may take several weeks.


Application Notes

  • Mix according to label instructions
  • Use a non-ionic surfactant if required by label
  • Spot treat affected areas rather than blanket spray
  • Avoid irrigation for several hours after application

Granular Option Available

Prefer a spreader application? See Vexis Granular Nutsedge Control.


SedgeHammer Plus provides targeted, professional-level control when standard lawn weed products fail.
