Ortho GroundClear Weed & Grass Killer is a powerful way to quickly clear weeds like dandelions, chickweed, nutsedge, and moss as well as unwanted grasses from patios, walkways, landscape beds, and gardens. You'll start to see results in just 15 minutes with weeds going from green to brown in under 2 hours. You can apply any time of the year when the winds are calm and weeds are small (3 inches tall or wide) and actively growing. Mix the Ortho GroundClear Weed and Grass Killer concentrate with water and apply with a tank sprayer. Just 1 pint of concentrate mixed with 7 pints of water is enough to treat up to 300 sq. ft. For hard to control perennial weeds or extremely dense weed growth, mix 1.2 pints (19.2 fl. oz.) of the product with 6.8 pints of water to treat up to 300 sq. ft. Plus, Ortho GroundClear Weed & Grass Killer is OMRI listed. Difficult to control weeds may require more than one application for complete control.
