However, one should still be cautious and follow all safety instructions carefully.

In terms of environmental impact, the product uses three types of weed killers, which raises some concerns about potential effects on surrounding plants and soil health if not applied correctly. Also, it might leave some residual activity, which could affect new plant growth in treated areas. If you are looking for a potent weed killer that is easy to use and offers quick results, the Ortho WeedClear Weed Killer is worth considering, especially for larger lawns.

It effectively covers 375 square feet with its 1.25-gallon volume, providing ample coverage for driveways, sidewalks, patios, and other non-lawn areas. However, this product is not selective, meaning it will kill any vegetation it comes into contact with, which can be a drawback if used near desired plants.

Furthermore, safety for pets and children is a concern, as the product should be used with caution in areas accessible to them. The environmental impact is another consideration, as chemical weed killers can have adverse effects on surrounding ecosystems. Users should weigh these factors to determine if it fits their specific needs for weed and grass control.
