Overview

Ortho WeedClear Lawn Weed Killer Concentrate is designed for DIY lawn care, delivering a concentrated formula that targets common weeds while protecting your turf when used as directed. It targets over 200 major broadleaf weeds and grass weeds, including dandelion, chickweed, clover, crabgrass, foxtail, and other listed species. When applied correctly, it aims to reduce visible weed growth without harming your established lawn.

Key benefits

  • Kills listed weeds to the root and helps curb regrowth when used as directed, across a range of common lawn grasses.
  • Fast-acting performance with results that are often observed after a single application, depending on weed type and growing conditions.
  • Rainproof in about 1 hour after application, giving you flexibility within your weather window.
  • Works on lawn grasses including Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, and Zoysiagrass when diluted and used as directed.
  • One 32 fl oz container covers up to 5,000 sq ft, offering broad-area convenience per bottle.

How to use

  • Dilute the concentrate according to label directions and apply with a tank sprayer or the Ortho Dial N Spray for precise coverage.
  • Apply to young, actively growing weeds when daytime temperatures are between 45°F and 90°F. Do not apply to Bermudagrass when temperatures exceed 85°F.
  • Do not allow people or pets to enter the treated area until sprays have dried.
  • Avoid applying to St. Augustinegrass, bahiagrass, bentgrass, carpetgrass, centipedegrass, dichondra, seashore paspalum, gardens, or ornamental plants.

Coverage and practical notes

One 32 oz bottle treats up to 5,000 sq ft, making it suitable for medium-to-large lawns. For best results, apply to actively growing weeds and monitor treated areas for follow-up treatment if needed.
