    It works better than I thought
  

*by T***G on Reviewed in the United States on October 16, 2022*

The stuff works pretty well. After I read the reviews and they actually seem like legitimate and not fake reviews, I thought I’d give it a shot. I just laid my sod a few weeks ago.  Most of the yard is looking nice, but there were a few brown spots near the seams. I thought after reading the reviews I would give this a shot. In the first picture you can see how the spots were browning, in the second picture, you can see how new green sprouts are coming through the brown and greening it back up, and then the last picture you can see how the majority of the rest of the yard is standing tall and looking green.These results are after about one week, but I Started the new green sprouts coming through the brown after 2 to 3 days.I just ordered their purple label 8 – 0–0 fertilizer and will be giving that a shot. I will be spraying it tomorrow and update that review after a week or two.The only thing I was hesitant about with some people said it did not spray very well, but I read one review where the guy said to shake it like crazy. So I did just that and I had no problem whatsoever. The only advice I would offer would be to make sure you watch the level in the bottle to make sure you were evenly spreading it throughout the yard appropriately and not using too much too fast if your water pressure is too high.  My pressure on the secondary valve is pretty high and I used more than I should have on the first quarter of the yard. That is looking very bold and strong and come spring I will use these products again and be the envy of the neighborhood.

    Grass fertilizer

    Product works but spray nozzle does not
  

*by B***S on Reviewed in the United States on April 20, 2024*

The first time I got the product, worked like a champ out of the nozzle and the result were great. The next 3 shipments not so well. The product will not spray out of the nozzle provided. No matter what I do. I ended up manually applying it and I won’t do that again with such a big yard. Wished it worked out of the nozzle because the product really did do magic!Edit: The seller got back to me and gave me some hints to make the nozzle work better. More pressure, or upside down and then turn on the applicator. Who knows just yet but I am definitely try it again since the product worked as well as it has for my grass. They did issue me a refund and I turned right around and bought another unit to try the suggestions. And even if it doesn’t, I bought a power sprayer to help. My grass starts to flourish when I use this product.
