This stuff is great! I love that it is safer than Round Up and works so well. You need to use more than with RoundUp which is fine with me. The only challenge is that the end of the tube inside the bottle floats to the top and makes it hard to get the spray to work. I am trying to find something to weigh down the end. I put a picture here so you can see the difference between the green (untreated) with the brown (treated).

This definitely works! After both of my parents passed away from cancer, I've become much more aware and conscientious of the chemicals we use and have tried to replace all or most with organic and safer options. My husband has been addicted to using RoundUp for years and we were both amazed by how quickly this works. We mainly use it on the rocks in our landscaping when weeds pop up around our bushes and flowers. Within a half hour, the weed is shriveled. By morning, the weed actually seemed to disintegrate into the rock. I could hardly even see it. Normally, we have to go back and pull up all the dead weeds after using the RoundUp. I don't have to do anything after spraying. It's awesome!

This weed killer is unbelievable! I don't like using chemicals and thought I would try this because of the reviews. I have decorative stone throughout my property and have a bird feeder in back - well of course birds are not neat and scatter seeds which results in little sprouts all over the place. Still wanting to feed the birds but not wanting to use chemicals, I ordered this and used it for the first time this morning. The weeds and grass that was growing up in the stone are now brown and wilted! I will be an ongoing customer for sure and have already recommended this to my neighbors

okay I hardly ever write reviews and to be honest with you I was skeptical to use all natural weed killer and thought they reviews I was reading were fake. But I took a chance and bought this stuff. (Because I kind of felt guilty using the other stuff like Roundup due to it harming birds and everything else too)
Back to the review, when I opened the box--- I had a letter from Rudy- the owner. He let me know about his product (which happens to be actually right down the road since I live in Florida too). Anyway blah blah blah I tried the product & just look at the photos!!! U will see it actually works faster than the hard chemicals. 24 hours later the weeds were dead / dying.
Good stuff!
ThxRudy!

Prior to living in our current home, my husband and I both lived in apartments prior to moving, so we had zero experience in landscaping and how to maintain and care for a lawn. My home is mostly rocks because of the dry environment the state is in, so I didn't know how to take care of weeds when they started popping up. Due to my lack of knowledge, more and more weeds popped up in larger patches so I got to work on figuring out what to do to remedy the issue. I was scared because I heard such terrbile things about weed killers. I happened to come across this product in my search and in all honesty...what a huge difference it makes! I can't believe how much better the back hard looks. It works fast and the resulta are amazing. This will continue to be the product we purchase to get rid of weeds.

I took a chance on this natural product and I am so glad I did. This stuff is great! It really works and you see the results in no time at all. This is by far the best non-pesticide weed killer I have tried. The only thing I would improve on is the tubing and the sprayer as even though I followed the instructions the tubing still curls and you have to adjust it as you are spraying I also lost some product from the spray nozzle when I set down the bottle and the sprayer was hanging down. The vinegar smell does not bother me at all like I said way better than pesticide. I will buy this again.

Ok so far I’m impressed! I purchased this weed killer to clear up weeds growin in a new walkway we were creating and to use on a brick patio that previous owners didn’t lay correctly. Weeds grow through it all summer. Last night I sprayed a few weeds including a big burdock growin in our new area under a new deck and the photo shows what it looks like today. Dandelions and other weeds were quickly killed and I just sprayed the patio and in a just a few minutes everything is wilting. I’ll update this review later when I see how well it did long term but so far I find it to be effective and just what I was looking for. I love that’s it safe for everyone and my pets and that I can plant 24 hours later. Great product. Oh, and I did put this into my own sprayer after reading other reviews. No problem at all.
