Perhaps you’re in portions of Canada, New England, or other areas that are restricting the use of conventional herbicides. And you’ve got crabgrass. And chelated iron products won’t touch it. You need an alternative, something that won’t kill the turfgrass but will control crabgrass. You need Frostbite.
Frostbite is the first organic solution to crabgrass control within turfgrass. And even better: Frostbite uses environmentally benign carbon dioxide and the water within the weed to rupture cell walls. The Frostbite sprayer is a device that damages weeds, but it’s much faster to use than hand tools.
