579 Vinegar Weed & Grass Killer, Approved for Organic Production, Pet Safe, Glyphosate Free Herbicide, Quart, 1, Light Yellow

I bought this a couple weeks ago. Tried it on some Canadian thistles one of the toughest plants to get rid of. I tried 5% vinegar and other off the shelf products from the big box stores. Nothing worked. Sprayed this on five plants as a trial and the next day they were brown and shriveled. Tried it on dandelions and they're dying. This is a GREAT product.

This is a powerful vinegar that kills unwanted new vegetation almost on contact and kills mature vegetation within hours or overnight at worst. Unfortunately, this great product is paired with an application tool that is disappointing. The sprayer is undersized and uncomfortable to use. Specifically, the straw diameter is small so multiple squirts are required to cover the target. The sprayer trigger has sharp corners that eventually cause discomfort. I'll buy the gallon again but provide my own spray bottle.

I weed the old-fashioned way--I pull them. However, at the end of my gravel driveway thee weeds encroach from the lawn and form a tightly-woven network. Because they are embedded in the gravel, they are really tough to pull. So I considered using Round Up or some similar spray, to use in these limited areas, even though I was hesitant to spray chemicals on my property. As I browsed Amazon for a spay, I saw this one and took a shot at it. I sprayed it on the encroaching weed network, left it for a maybe 5-6 hours, and when I went outside again, to my surprise, it had wiped a several foot stretch of the embedded weeds network totally out. I have used Round Up as a landscaper, and this stuff works equally well. There were a few weeds that turned a bit brown but didn't die, like clover, but I just pulled the few stragglers and mission accomplished.

I wanted so badly to love this product because I have small children and want safe chemicals to keep weeds out of my patio. This would make the weed look dead but by the next week or so the weed was back. I reapplied many times with the same results. Felt like a waste of money.

Saturday morning I walked around my yard and sprayed several weeds and grass. I came back in the afternoon and everything had started to wilt. Now, Monday, all things I sprayed are dead and withered. Pretty good results for vinegar.

I recently redid 2 flower beds. I added weed control black garden roll, added soil, added mulch and the next thing you know, I had grass growing everywhere! I used this product as directed and the grass turned yellowish, but didn't die. I repeated the application and a little more turned yellowish, but nothing died. I still have grass growing so I don't think this product is worth the money.

Immediately upon delivery I tested the product on one "American Burnweed" of several growing in yard mulch. Checked back an hour later and the weed is TOAST. (Note this was done in direct sunlight on 90 degree day.) Looking forward to cleaning up the rest of the weeds with this great product and raking out of the mulch rather than pulling by hand. Not certain yet if I will risk spraying on lawn weeds since this will surely kill healthy grass if not applied carefully.

Saw this product reviewed online, and it does indeed kill weeds within 24 hours as the man said. I use it for spot treatment on the driveway and in my rock wall. Very strong vinegar odor, and be careful of blowback into your eyes if you use the spray feature instead of stream. Works so much better than the stuff I get at the local garden centers, which usually required multiple applications. Love seeing those brown, shrivelling weeds going bye-bye.
