Rated 5 out of 5 by from Patience is a virtue. Time proves it works. My neighbor turned me on to the product. He highly recommended it, so I purchased it in his word. I hadn’t used it yet, but I witnessed him spraying all the weeds in his front yard. I kept an eye on his weeds, and after 1, then 2 weeks, nothing. I was wondering if this stuff really worked. Then on the 3rd week, the weeds turned brown, and soon after — to dust. The instructions say to use 1.5 to 2 ounces per gallon. My neighbor said to use 4 ounces per gallon, so I did. My weed coverage in my front yard, which is all rock landscaping (much to my chagrin), was extensive — large green weeds everywhere, thanks to the recent heavy rains. I sprayed every square foot of my front yard, and 3 weeks later, all the weeds were gone. From the street, you cannot even tell there were any weeds to begin with. I live in the desert Southwest, so I don’t get what others are writing about their weeds gone from a few years to a week. All I can say is — be patient; the weeds will be eliminated. This product is worth the cost, in my opinion.

What is the difference in this product and the FarmWorks Grass & Weed Killer 41% Glyphosate concentrate 2.5 Gallon for $54.99? I have used this product with great results but it appears to be more expensive than the FarmWorks product...

Asked by: Jefany
This product has the same active ingredient as the 41%, it is just a little more concentrated. The mix rate for the 50% would be a little less (2-2.5 ounces per gal) than the 41% ( 3 ounces per gal) for general weed and grass control.

It can be safely used around existing trees as long as no drift or spray gets on the trees.

Can I safely use this product on dormant Bermuda lawn to kill other grasses and weeds? I don't see that use on the label.

Asked by: Philip MH
Yes, Groundwork 50 % Super Weed & Grass Killer can be used on a dormant Bermuda lawn to control weeds and grasses. The Bermuda needs to be fully dormant or it will be killed along with the weeds. Daytime temperatures should be in the 60’s when applying to make sure the weeds are active and take up the product.

Does this kill Knotweed?  I didn't see any label on the website.  If you had to suggest a product to kill a large (almost an acre) of knotweed what would it be and which one would be the cheapest?

Asked by: farmer diana
Yes, it will kill Knotweed. Please check your email for additional information concerning the specs and label.

when is the best time to apply this product to kill bermuda grass? should it be a certain temp outside for this to work properly?

Asked by: KDL75
Temperatures should be at least 65-70 degrees when applying but the Bermuda needs to be actively growing for the product to be taken up by the plant.
