I sure hope this works. The claim of visible results in 3 hours is not happening. 24 hours after application the sticker weeds are all standing straight up and healthy looking. I put on plenty of product at roots and leaves.

    Really works but be careful with it. If I’m using it in my flower bed I shield my other plants with a piece of cardboard to protect them from the mist. I also pour some into a small disposible container and use a small foam brush to brush on weeds that are in my moss ground cover. I always use disposable plastic gloves. I depend on Roundup and use it with caution.

    Round up might be one of the best weed killers I have ever used. Coming in the spray bottle for instant use is the best! I used it along the edge of my driveway, where it connects to the street a pretty lengthy stretch, and one usage and those weeds and grass were gone. Needless to say, I will always keep it on hand for quick usage.

    I use this mostly on bitter sweet- you can pull it up by the roots but an root left behind and you have anew plant. This has a very directed spray so you can confine the spray to a small area-- I also wear plastic gloves to prevent any Roundup from getting on my skin. None has leaked out of the bottle and with care you can really effectively kill some plants. Years ago I used Roundup to clean the borrow ditch on the road by my house of poison ivy and it did a great job. I hit the patch twice over a month or so- it has been 20 yrs and no PI has grown back.

    Reviewed in the United States on March 3, 2013
    Product Packaging: Standard PackagingVerified Purchase
    Ever heard the saying "A little goes a long way?" Well in this case it doesn't apply here. This product does work, but i got tired of the foam part, so i switched the nossel over to spray/stream. I think foam uses more liquid, and this foam goes away fast. I never killed plants with a spray and i dont think it says the minumum amount to use to kill the weeds. I have a big property and this only let me buy 3. Well 3 was not enough. I got a lot of bushes, but I think of this size as killing driveway weeds, because it didnt seem to cover a whole lot, that or i sprayed way to much to try to kill the weeds. But in the end it got the job done. Just wich I could have ordered more. I was able to also find this in my rite aid for 4.99 and for the 1 gallon for 10.99. So I may or may not go back and get more from there. It says 6 hours you notice it working, but by the next day it looked like someone ran through them or that someone drove over them. Very happy and highly recommend. Very reasonable and it works on the stubborn Arizona weeds for those fellow folks in desperite need of good weed killer.
