I have patches of yarrow in my lawn that are quite pesky. Will speedzone be effective? Any recommendations for how to apply it for yarrow?
SpeedZone Southern Herbicide is labeled to eradicate yarrow. The rate you will use will depend on your grass type. For a cool-season lawn, you will mix 1.5 to 2.2 fl. oz to 1 gallon of water per 1000 sq ft. For a warm-season lawn, you will mix 0.75 to 1.5 fl. oz to 1 gallon of water per 1000 sq ft.
