The driveway weeds were dead about 3 hours later! I also used it in a flower bed with same results!! Just be careful you don't get the flowers or their leaves wet.
I did have a problem with the sprayer so I poured it into a smaller spray bottle. I liked this better anyway because the smaller spray bottle was so much easier to handle.
This is a great weed killer!

A bit expensive for 2 reasons...
1. Needed to get a other sprayer because this one is garbage! Sprayed like 2x and then it stopped working.
2. It takes a lot of product to work. I used the whole gallon and didn't even get 1/4 of the yard.

Like others said it kills everything though, so DO NOT USE IT ON YOUR NICE GRASS unless you don't mind it dying so you can get rid of the weeds and then have new grass.

It will smell like vinegar for a little bit.

Best to do it on a sunny day.

I was shocked at how quickly and efficiently this worked! Weeds literally started to wilt right away and they're brown by the next day. However, I messed up and left the spray nozzle attached to the bottle and layed it on the ground. The next day the bottle was completely empty. It siphoned through the little hose and drained all over the cement. So be careful of that, it was a big waste of money in that respect, but I'm absolutely ordering another bottle!

Dog mom here, this product works well. It does not work as fast as the chemicals but I rather take an extra day to crush the weeds versus poison my dog with chemicals! I appreciate this alternative and it works! You may have to spray it on a few weed more than once or do it before the sun is at the high point during the day. 100% recommend

This product worked like a charm for me. I initially bought because I have dogs who roam my back yard, and needed something safe for them. But I was pleasantly surprised that 2 weeks after I used it (and heavy rain), there was not a single weed where I had sprayed! This entire rock area (pictured) was covered in tiny weeds. Clovers mostly.
The spray nozzle is a little tricky, make sure to screw both the cap AND the nozzle to the hose or it will leak.
I would highly recommend this product! It's both effective and safe for beloved pets!!
