If you’re looking for rapid action, this product stands out in the crowded market.

Broad Spectrum

The product can control a vast array of broadleaf weeds like lambsquarters, cudweed, and oxalis, as well as grasses like crabgrass and bluegrass. It even works on more stubborn weeds, although multiple applications might be required. This makes it versatile enough to be used in a variety of settings—hardscapes, landscape beds, and around vegetable gardens.


For those concerned about the environmental impact of their gardening products, you’ll be pleased to know that Ortho® GroundClear® is OMRI listed, making it suitable for organic gardening. This means it doesn’t contain any synthetic chemicals that could harm the soil or the environment.


It is also rainproof in 2 hours upon drying, making it an excellent option for those in more rainy locales.

Where to Use

Ortho GroundClear is specifically formulated for use on hardscapes like walkways and driveways, as well as in landscape beds and around vegetable gardens. Just make sure you apply it directly to the weeds you want to eliminate.

Active Ingredient

The active ingredient in this product is Ammonium Nonanoate, an organic compound effective in killing weeds but generally less harmful to the environment compared to synthetic herbicides.


While Ortho GroundClear is extremely effective for most types of weeds, it’s worth noting that for more stubborn types like Bermudagrass, Dandelion, and Nutsedge, multiple applications may be required for complete eradication. Therefore, patience and reapplication are key for perennial or more established weeds.

If you are unsatisfied with the product, Ortho offers a full refund upon presentation of proof of purchase, making this a risk-free option for those wanting to try it out.
