  • Great product for gripe weed
Style: Concentrate
This stuff was a god send fighting gripe weed. If you’ve never fought it, it is one of the hardest weeds to eliminate. Worked well on other weeds as well. Wish I could find it local.

  • THIS STUFF WORKS!!!
Style: Hose Spray
I love this stuff. I have been using it for the last few years. I used to clean a guy's house that was a plant chemist/plant scientist. He had multiple degrees but his business was making chemicals for use in agriculture and gardening. He told me about this and it has saved me soooo much time and money. It doesn't kill weeds, it prevents weeds from germinating and spreading. I do one spray in the spring after the snow melts and then once at the end of summer. I did forget to do it at the end of last summer before the weeds started coming back and so I did have to deal with that and now I have crab grass growing in my lawn. :( But since I sprayed it again at least it hasn't spread. I do have a bare spot on my property that hasn't been landscaped yet. So in order to keep it from growing weeds uncontrollably I spray this. If weeds have already started to grow, I spray this on first and then wait about a week then spray with a weed killer. Works every time. If you kill the weeds first and wait to use this, during your waiting period there are new weeds germinating. I know they are unsightly but it's worth it in the long run. I did once get a defective bottle so I got a new one and once that was empty just put the weed preventer in the new bottle, but other than that, I have had no issues with this product. ... show more

  • Works
Style: Hose Spray
Be sure to water the area as instructed, I waited about an hour and a half. I had allot of different weeds mixed in the grass and it has taken a few applications but weeds are pretty much gone.

  • Saved Me Hundreds vs Professional Weed Control
Style: Hose Spray
I’ve been using this, season-long spray for several years now and keep it on a subscription every three months. Timing the application is critical, but if you follow the schedule, it works extremely well. Since switching to this product, I’ve been able to avoid paying for a professional service and save hundreds of dollars every year. It’s been reliable, consistent, and effective when applied as directed. If you’re willing to do a little DIY work and pay attention to timing, this is a great alternative to expensive weed control contracts. ... show more

  • Want to build super weed immunity?
Style: Concentrate
Killed initially. Weeds kept popping up in same area within a month or so. Required more concentrated dose to kill, until inevitably, it wouldnt kill the weeds at all...now I have super immune weed variations to contend with. It's like misuse of antibiotics, but for your landscape. I'm not kidding, the HOA is all over me now. ... show more

  • Avoid!
Style: Hose Spray
I’ve used numerous weed killers over the years, and this has been the worst to date. I applied exactly as per the instructions, and the only thing it was successful at killing was my grass. The clovers seemed to thrive after application as seen in photos. Complete waste of money and now my grass is dead! ... show more

  • Works for three months or more!
Style: Concentrate
I imagine anyone who had their grass die after using this, has one of the variety's of grass that it says not to use it on. Also, timing is everything. You don't use this in September when you should be seeding like I read another reviewer had done. Also, you don't put it on newly seeded yards unless you want it to kill the grass seed as it germinates. Also, do not aerate your yard after you put this down as it works season long by creating a herbicidal barrier on the surface of the ground. Aerating disturbs this barrier and allows the weeds to grow and establish. My personal experience/observations Early September through November and Late March through May are transition months when your yard is changing between cool and hot season weeds. Your wasting your time and money applying then. At least around zone 7 you are. I apply it when the seasons weeds are first up, but have not produced blooms or seeds yet. This window of opportunity is very small I have found. Sometimes only a couple weeks. You can put it down earlier, but it may not get you through the whole season. and a second application may exceed the max annual rate. My yard never looked better than after I started using this product. Some other personal suggestions: 1. Get a soil test. 2. Only Fertilize in the Fall/Winter. 3. Fertilize in three separate applications a month apart. 4. Only apply Bayer Season Long Weed Control AFTER over-seeding is well established. 5. Use a blend of grass seed. Not just one type/brand/variety. ... show more
