Ortho GroundClear Year Long Vegetation Killer1 - Concentrate, Visible Results in 3 Hours, Kills Weeds and Grasses to the Root When Used as Directed, Up to 1 Year of Weed and Grass Control, 1 gal.

CLEARS EVERYTHING can not be stressed enough!!

I get a lot of weed growth both in my sidewalk and driveway joints, and in my back yard where I have river rock instead of grass. If you are going to mix it in your sprayer, make sure you have at least a two gallon sprayer because the ratio is 24 ounces to 1 gallon of water so you end up with almost a gallon and a half. What I do is mix two gallons in a washed out kitty litter container and use that to pour into my sprayer. I keep a plastic quart measuring cup in my garage and a dedicated funnel. Don't be a guy and mix it in the kitchen! I am very happy with how long it has been keeping the weeds from returning. I've only had to re-treat one sidewalk joint and a few spots in the backyard. Be advised though that this is a ground clearing agent. It will kill everything, including grass and flowers.

Seems, at the first, to be a little slow on the death march, but seems to kill it all.

So I grabbed this Ortho GroundClear Year Long Vegetation Killer with visions of a weed-free paradise dancing in my head. “One application,” it promised. “Year-long protection,” it boasted. And me? I was ready to become the weed terminator my lawn desperately needed. Fast forward a few weeks, and I’m staring at my yard like a detective in a low-budget crime show, trying to figure out: Did the weeds die? Did they just play dead? Or did they throw a secret party and invite all their friends? Honestly, I’m not really sure if this stuff worked or if it’s just gifted me an entire season of anxiety about whether I’m doing gardening right. Some patches look clearer, others look stubbornly green — like the weeds know they’re part of some weird reality show and are refusing to go quietly. Bonus points for the fact that it sounds super science-y, so I feel like a lawn-care chemist even if my results are… meh. In conclusion: If you want a product that might kill weeds and grasses and might just make you question your gardening skills, this is the concentrate for you. For guaranteed results, maybe just hire a landscaper. Or take up knitting.
