Ortho GroundClear Year Long Vegetation Killer2 Concentrate - 2 gal

In this review we look at Ortho GroundClear Year Long Vegetation Killer2 Concentrate and who will get the most from it. The bottom line: this concentrated weed killer is for homeowners or property managers who need long-lasting vegetation control on hardscapes and want a product that becomes rainproof quickly. The formula is designed to kill existing weeds and prevent regrowth for up to one year when applied as directed, and it is sold as a concentrate that dilutes for use in a tank sprayer, making it useful for treating larger patches without repeated weekly applications.

Key Features

• Kills and prevents for up to 1 year: Provides extended control of weeds, grasses and existing vegetation so treated areas stay clear without repeat spot treatments.
• Fast-acting and rainproof: Starts working immediately and becomes rainproof in about 1 hour, reducing loss of effectiveness after light rain.
• Concentrate for tank sprayers: Mix 24 fl. oz. per gallon of water for application, which lets users adjust volume to cover different sized areas.
• Coverage from a single container: One 2 gal. container makes enough diluted mix to treat up to 3,200 sq. ft., useful for driveways, walkways and larger hardscape zones.
• Intended for hardscapes: Formulated for driveways, sidewalks, fence lines, paver patios, gravel and parking areas where no plant growth is wanted for at least a year.

Who It's For

Ortho GroundClear works best for homeowners, landscapers and property managers who need a single-season solution for nonplant areas such as driveways, paver patios and gravel strips. It is especially helpful when users want to treat larger hardscape areas quickly and avoid frequent reapplications.

It is not intended for use where desirable plants, lawns or garden beds are present; anyone who needs selective or spot treatment near sensitive plants should look for a different selective product or use careful application methods to avoid contact with vegetation to be preserved.

Pros & Cons

Pros

• Concentrated formula covers a lot of area from a single 2 gal. jug, offering convenience for larger jobs.
• Fast action and rainproofing in about 1 hour minimizes lost product after unexpected showers.
• Designed specifically for hardscapes, so it fits common nonplant use cases like sidewalks and parking areas.
• Simple dilution instructions make it straightforward to use with a standard tank sprayer.

Cons

• Some users report mixed results on longevity and complete kill, so performance may vary by weed type and application conditions.
• Requires careful application and avoidance of desirable plants, which limits use near planted beds or turf.

Our Verdict

Ortho GroundClear Year Long Concentrate is a practical choice for anyone who needs durable, nonselective weed control on hardscapes and wants a product that becomes rainproof quickly.

Those with sensitive nearby plantings should exercise caution or choose a selective alternative.
