Ortho GroundClear Weed & Grass Killer Concentrate is a fast-acting, contact herbicide formulated for clearing weeds and grasses out of hardscape areas - patios, driveways, walkways, gravel paths, and landscape edges - where you want quick visible kill rather than a slow root-deep systemic. The concentrated liquid mixes with water in a tank or pump sprayer; the 1 Gallon size is the bulk option for clearing larger properties.

• Kills dandelions, chickweed, crabgrass, moss, and other listed tough weeds and grasses on contact
• Visible results in hours
• Rainfast in just 15 minutes after application
• Concentrated - mix with water in a tank sprayer or hand-pump sprayer for broad coverage
• Designed for patios, walkways, driveways, gravel paths, fence lines, and around landscape borders
• Size: 1 Gallon concentrate

Selection Tip: The 1 Gallon size is the bulk pick - the right choice when you are clearing a large gravel lot, long fence line, paddock perimeter, or commercial walkway. If you are only cleaning up a residential patio and driveway, the 32 oz size is more practical and easier to store.

How It Works: Unlike a systemic herbicide that travels into the root, contact killers like GroundClear burn down the green tissue they touch. That gives you faster visible results (hours rather than days) but well-established perennial weeds with deep roots may regrow and need re-treating - which is also why GroundClear is a better fit for hardscape and gravel clearing than for stump or established-perennial removal.

Mix & Use Tip: Mix in the exact ratio printed on the label and spray to thoroughly wet the foliage. Apply on a calm, dry day - rainfast time is short (15 minutes), but heavy rain during application washes spray off before it works. Shield desirable plants from drift; this is a non-selective spray.

Note: Keep children and pets off treated areas until the spray has fully dried. Read and follow all label directions and precautions.
