Kills weeds quickly. As for grass, the jury is still out. Waiting to see how much longer, and if second application is required. To be continued.

'I wound up using the whole bottle on just my 1/4 acre backyard alone over a week and you can't even tell .

Round Up has included a second chemical, Diquat, that was previously restricted b/o toxicity. This second chemical slows the effectiveness of glyphosate and, most importantly, extends the effect on surrounding plants. The beauty of glyphosate was that it could be used in beds.

Did kill the weeds if anything got greener and they grew.

This does a nice job on killing everything on my walkways where both broadleaf and grass sprouts. You have to be careful around the edges as rain will move it out into the grass and kill it leaving brown spots. So don't spray it right up to the edge.

I bought 2 jugs of this product. This product didn’t work as I expected. I followed the recommendations for the mixers and have to spray an area in my yard twice. On a different area I mixed a little more thinking it would do the trick but it did not work out as I expected.

Works OK on the weeds have to use way more than recommend. It works great on the grass

The first time I used this I thought it was not working. After a week, the weeds and grass looked healthier than ever. Did I accidentally spray fertilizer? However, after about 2 weeks everything I sprayed was dead, very dead. So, just be patient and it should kill anything green you sprayed.

VERY slow acting. I had to do two coats and still not 100% kill. I would upload a picture for reference but no way to do so.

It took several days to work, but all the weeds and grass growing up through my gravel driveway are dead as a hammer now

It did not do as stated I mixed according to instructions with no results. I added more product to the mix and the results were very disappointing

I have been using kilzall for years with great success on killing weeds and problem grass. However, lately I have been noticing that once the weeds or grass are dead, in some areas, a different form of weeds quickly begins to grow within a week or two of application. I'm not sure why this is happening. I will still continue to use the product because it does kill the initial weeds and grass, but it's getting a little aggravating when something else starts popping up within a matter of days. Thanks to do my own.com for a nice transaction and quick shipping.

Absolutely in awe as to how well this worked. Within two days all weeds were gone. What an amazing find. So glad this just popped as I was looking for another product.

Works great.. I do all the edges of my lawn so I don’t have to trim and get right up next to the fence or stone.
