Prime Source Halo Herbicide

4.6

Best targeted solution for homeowners managing stubborn nutsedge and broadleaf weeds.

This is the surgical strike you need for stubborn nutsedge and broadleaf invaders that standard treatments miss. It’s remarkably safe for your lawn, though you’ll have to be patient—it works by systematically shutting down growth rather than scorching the earth, meaning you won't see total clearance for about two weeks.
