Use Ortho GroundClear Super Weed & Grass Killer1 to kill 175 types of tough weeds and grasses including crabgrass, dandelion, nutsedge, and oxalis (as listed). Apply this ready-to-use spray around landscape areas, patios, walkways, gravel, mulched areas, along houses and fence lines, and on driveways when weeds are actively growing and the air is calm. It's fast-acting - weeds absorb it on contact so you'll start to see weeds and grass wilt within hours and completely die off in 1-2 weeks.
Application is easy thanks to the attached continuous spray Comfort Wand. One ingredient works on contact while the other two ingredients are absorbed and move deep into the weed. Rainfall or watering 15 minutes after applying this weed and grass killer will not reduce the effectiveness of the weed control. A single application of Ortho GroundClear Super Weed & Grass Killer1 will start to control even the toughest weeds and grass right down to the roots, so they won't come back.
