Do NOT buy this just for weeds!!

5 years ago
This product is VERY misrepresented. It is NOT just a weed killer! It kills weeds, yes, but it also kills grass! This is a glyphosate herbicide, which is a vegetation killer. It kills basically everything that grows, just like regular Roundup. They shouldn't advertise this as a "weed killer" that "keeps your lawn looking nice." If you spray your lawn with this, you won't even HAVE a lawn!!!

Best stuff ever; can't buy it in CA

a year ago
Trying to figure out why other glysophates can be sold in CA, but not Roundup. As with all CA laws, this makes zero sense. Was able to buy better Roundup concentrates in the past and they worked great, but now I guess I'll just have to pick 2+ acres' worth of weeds barehanded. Stupid CA regulations.

Yes, I recommend this product.

It all died.

a year ago
I sprayed it on the weeds and unwanted grass in my corral and driveway. In a few days it was all dead so it worked well. This jug of name brand herbicide was regular priced the same as an off brand of the same strength chemical that was on sale but sold out.

Yes, I recommend this product.
