The Ortho GroundClear Weed and Grass Killer2 Concentrate is designed to tackle a wide range of weeds including dandelions, chickweed, crabgrass, moss, and more, making it highly versatile.

One of its standout features is its fast action, showing visible results within just 15 minutes and becoming rainproof in about 2 hours after application. This makes it a good choice for quick, effective weed control. The product has a broad application range, suitable for use around walkways, driveways, landscape beds, and under trees, but not for use on lawns or desirable grasses, indicating it is non-selective and will kill almost any plant it contacts.

This 32-ounce bottle covers up to 600 square feet, offering decent range for small to medium areas. Safety-wise, the product’s concentrated formula requires careful handling, and there is no explicit mention of it being pet or child-friendly, which might be a concern for households with pets or small children. In conclusion, the Ortho GroundClear Weed and Grass Killer2 is a powerful, fast-acting option for those needing to clear large areas of unwanted vegetation quickly and efficiently, but it should be used with caution around pets, children, and desirable plants.
