Fast-acting, with results in one application

Weeds like dandelions, crabgrass, and clover can quickly take over a healthy lawn, competing for nutrients and water while creating an uneven, patchy appearance. Ortho WeedClear Lawn Weed Killer Concentrate targets these stubborn invaders at the root level, delivering visible results after just one application. This fast-acting formula works on common lawn weeds including chickweed, foxtail, and clover without damaging your grass when applied according to label directions.

What sets this concentrate apart is its selective action. It eliminates broadleaf and grassy weeds while preserving the health of popular turf varieties like Bermudagrass, Kentucky Bluegrass, Fescues, Ryegrass, Buffalograss, and Zoysiagrass. The concentrated formula means you mix it with water before application, giving you control over coverage area and allowing you to treat larger lawns cost-effectively. Because it kills weeds down to the roots rather than just burning back the foliage, you get longer-lasting results with fewer repeat applications.

Who Is This For?

This product works well for homeowners dealing with persistent weed problems in established lawns. If you’ve tried pulling weeds by hand only to see them return weeks later, a root-killing herbicide offers a more permanent solution. It’s particularly useful for those maintaining larger lawn areas where manual weeding becomes impractical. The concentrate format suits anyone comfortable mixing products according to label instructions and using a pump sprayer for application. If you have one of the compatible grass types listed and want to reclaim your lawn from invasive weeds without starting over, this targeted approach lets you spot-treat problem areas or broadcast across the entire yard.

Bottom Line

Ortho WeedClear Lawn Weed Killer Concentrate delivers on its promise of fast-acting weed control that targets roots without harming your grass. The concentrate format provides good value for treating larger areas, though it does require proper mixing and application equipment. For homeowners tired of battling dandelions, crabgrass, and clover season after season, this selective herbicide offers an effective path to a cleaner, more uniform lawn.
