Grass that grows in undesirable locations, such as between the cracks of a sidewalk, can be killed with chemicals called non-selective herbicides. Every herbicide, even ones with the same active ingredient, can have different strengths. Therefore, purchase herbicides in a ready-to-use container for easy use.
However, if you try to kill this noxious weed with selective herbicides that kill grassy weeds, youâll waste time and money. An effective solution is to use Roundup, which contains glyphosate -- the only nonselective herbicide that kills nutgrass.
