    • The safest and best weed killer out there.
Style: Ready-To-Use Size: 128 oz
My husband wanted something safe to kill the weeds and grass on the sidewalk and this works in 2 to 3 days. It is organic and safe . No more killing my flowers because of overspray.

    • Not effective
Style: Ready-To-Use with Power Sprayer Size: 128 oz
Wow is this ineffective. At best it makes the plants it sprays on brown a bit in the sun. Doesn’t do much to wilt, arrest, or kill any weeds I’ve tried it on.

    • It works good.

Review Image by Janet Howard Janet Howard
This killed everything I sprayed within about 3 hours. It's also rain resistant within 3 or so hours of spraying. I would have given 5 stars but the box had a wet spot on it when I opened it and saw that the weed killer had leaked. It was sealed in a bag but it still got through. Reason being there was a crack in the handle on the container. I wanted to test the spray before returning but it worked so well I'm just going to get out my duct tape for that crack. Don't know how much fluid I lost in shipping, but it still sprays so I'm happy. The odor is strong, but it dissipates not long after applying. Just suggest they package it a bit better, the handle cracked and the bag protecting spills, leaked. Thankfully it didn't get on anything else I ordered in the box. ... show more

    • This does not kill any grass (not mine anyway) but it kills weeds very fast
Style: Ready-To-Use Size: 32 oz
Revised Review - while deadweed brew did not work for my intended purpose and does not kill any grass that I have; It does kill weeds (clover pig ears etc) and it works VERY quickly. so I thought it only fair to change my rating and review . I bought this because I did not want to use toxic chemicals and it was recommended by someone at a very reputable nursery. Sometimes natural products take longer to work. I sprayed this liberally on the unwanted item . It has been 4 weeks (past my return window). Nothing - DID NOT WORK AT ALL - there were a few spots on a couple of leaves in a 3 square foot area and that is all. complete waste of money. ... show more

    • First time great, second time not so much.....
Style: Ready-To-Use Size: 32 oz
I live in Arizona and have a small yard with lots of gravel. FIRST USE - This spray WORKED GREAT THE FIRST TIME on mostly 6 inch tall mallow weeds, and grass that had invaded my side yard gravel. It killed the dreaded stinknet, too. One 32oz spray bottle did the side yard and half the front gravel and 3 weeks later everything I sprayed is still dead. SECOND USE - I bought a second bottle to do the rest of the front gravel. This time I noticed there are nozzle settings for narrow or wide spray and the wide spray setting does not concentrate enough product on the weed. USE THE NARROW SPRAY SETTING unless you want to waste tons of product. And then the SPRAYER STOPPED WORKING halfway through my second bottle and I had to pour the remaining product into a spare spray bottle, which did not have a narrow enough spray range so I was wasting product again. The second bottle would have done the rest of my yard, I think, if I didn't run into issues, but it's a small yard. I have very mixed feelings now because of the quality of the spray bottle and whether the price is worth it for a yard any bigger than mine. ... show more
