It is easy to use and guarantees weed elimination down to the root, with a consumer guarantee offering a refund if you are not satisfied. However, it cannot be sold in New York, which could be a limitation for some users.

The Ortho GroundClear Year Long Vegetation Killer2 Concentrate is designed to kill and prevent weeds and grasses for up to a year, making it a solid choice if you want a long-lasting solution to keep unwanted plants from growing on driveways, sidewalks, and other hard surfaces. It works quickly, starting to take effect right away and becoming rainproof within an hour, which means you don't have to worry about rain washing it away soon after application.

One 2-gallon container can treat about 3,200 square feet, so it covers a decent area for its size.

This product does a good job at keeping areas clear of vegetation for a long time, but it is a non-selective herbicide, meaning it will kill any plants it touches, so you need to be careful where you apply it. It is best for areas where you want no plants at all for at least a year, so it’s not suitable if you want to maintain grass or flowers nearby.

This product is well suited for those needing durable and broad weed control on hard surfaces, with fast action and strong rain resistance. However, it requires careful handling due to its strong and persistent nature.
