Roundup 32 fl. oz. Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Concentrate

Well, I usually don’t like using chemicals like this, but sometimes we really need it. I was treating some stubborn grass and it helped a lot. But because of the chemicals I won’t be buying again. Please use mask, and gloves when using this.

Worked very well

So I was very excited about receiving this to test it because we do have weeds, but the ingredients are super dangerous and it didn’t really kill our weed problem as expected

Three years ago, this product was outstanding. But for the last 2 years, it has only lasted 2 months before weeds come back up. My use and application for all 3 years has been the same. I am super careful to spray all the pebbles on my paths and the block patio and walkways. I can no longer recommend this product as meeting its claims of 365. Best is 2 months.

This stuff is potent. I use it every year in our gravel. It doesn't last 12 months, but it works fast and kills everything until next spring. Ive made a few applications right before a pop up storm and was worried that it wouldn't be as effective, but it goes to work pretty fast with results seen by the next day.

I have fibromyalgia and can no longer use a weed eater, so I was excited to be able to try this product. Mixing instructions are easy to follow and understand. I sprayed along the edges and within 24 hours, I started to see some yellowing of the weeds. Within 48 hours,they were turning brown. The video is at 3 days post spray. Im very happy with this weed killer.

Weed was coming growing through the pavers. So purpose is to use this weed killer to do its job so I can pull it out easily and resand in between. Easier application and I used a small sprayer bottle. This stuff is powerful and low maintenance last 12 months prevention! I have also weed growing between cracks of concrete side walk! I used a previous brand and would last for a short time. New growth will come back. This is my solution.

This item did great in killing weeds in many areas of my yard. I followed the easy instruction on how to mix concentrated liquid with water, and I sprayed away. It does how a smell, but not a problem at all. Weeds eventually wilted away. Best of all, it's guaranteed to prevent new growth up to 12 months.

I used this to kill the grass so I could edge my garden with mulch and it worked like a charm! I covered up most of the now dead grass but also pulled some near my garden gate and it came out very easily.

My husband was more excited about this than I was! We’ve used it a handful of times now and have enjoyed the results. Goes on easily and got rid of the weeds in all of the cracks in our driveway and around the edges. Would definitely recommend!

This seems to work well I used it on my patio and so far so good we will see how long it keeps the grass and weeds off of it. I useally have good success with round up products

Does the job and easy to use. Effective and the packaging is compact, making it easy to store in the garage! Would recommend if you’re looking for good value

This has worked wonders on a tree stump we took down that had so many weeds and grass that we wanted to repurpose. Definitely worth the buy and will buy some more! East to use and very effective!

I was actually worried this might not work because it rained after spraying. This was the before & after. Just one day after too. It was easy to use. Directions on the package.

We used Roundup 365 to tackle tall, stubborn weeds along our fence line, and it worked amazingly well. Within a day or two, the weeds started to die off, and the area stayed clean for weeks. It’s strong and effective — exactly what a busy mom like me needs to keep the yard looking tidy without spending hours weeding. Just a heads-up: make sure to use it carefully. I always apply it early in the morning when the kids are inside and avoid windy days to prevent drift. Follow the instructions closely, wear gloves, and keep it out of reach of children. Overall, I’m really happy with the results. It saves time and does what it promises!

Be careful it is concentrated! You can notice it working within 48 hrs. It’s great for killing small weeds but you have to use more of it for a larger brush.

Application was smooth in my precise sprayer. Very effective started to work within hours. Packaging is strong and will hold up in garage storage. Safety is typical for chemicals.

I am pleasantly surprised with this product, easy to use and if instructions are correctly followed very effective to control areas around the house with poison ivy,keep the driveway free of weeds, covering a wide area and the final result lasting almost a year.

This round up weed and grass killer was super simple to use . It worked great in my yard I have a small yard . I also used it. In my driveway . I have seen less weeds in my yard

I’m very happy with this weed killer, it’s super easy to use and it’s easy to mix. My weeds were dying within a couple of days. I haven’t seen any of my weeds coming back so I’m very happy about that, because I normally have to spray once a week. The packaging is very nice and easy to store away! I’m very happy with the way this product is working!

This is such an amazing product. I’ve been using it for about 2 to 3 weeks and I’ve literally noticed a reduction in weeds popping up in my plants in the garden. This is amazing because I grow all kinds of fruits, vegetables and herbs, so keeping the weeds away is essential. The price is amazing. Package is gray and the smell keeps animals away as well. I highly recommend recommended if you love gardening or a beautiful yard.

My favorite part about this weed and grass killer is how easy it is to use. Just dilute, spray and my dogs are ok to go near it writhin ep minutes once it is dry. I have river rocks in my back yard that get mossy and have weeds pop through so I can’t wait to see if this actually gives me 12 months of protection in one application!

Roundup works fast! I sprayed it on weeds in my driveway and saw them dying within a couple days. Super easy to use, just don’t get it near plants you wanna keep. Strong smell tho, and make sure it doesn’t rain right after. Still a go-to for stubborn weeds!

Powerful concentrate, kills weeds fast, even in rain, and seems to prevent regrowth. A bit pricey and not everyone sees the full 12 month barrier, but I’m impressed with the results.

This was very easy to mix up in a tank sprayer and even easier to apply. You do need to apply throughout all you are wanting to treat. This is not a spot treatment. I did wear a mask while using because this stuff can be strong smelling and with the wind blowing a lot where I live, it is best to be protected.

This product works great. The concentrated bottle allows you to use as little or as much as you need. I noticed my weeds wilting just days after spraying the product. The smell isn’t overwhelming and has a child safety lid.

I am a new homeowner, and my home is a new build. We started with no grass and just red clay. Weeds thrive in red clay, but this product has helped us keep the weeds at bay.

I recently tried Roundup Dual Action 365 weed and grass killer, and I have to say, it really delivered on its promise. I had an area in my garden that was overtaken by stubborn weeds that regular pulling just wasn’t tackling. After reading about this product, I decided to give it a shot. I followed the instructions carefully, making sure to apply it on a dry day. The spray nozzle was easy to use and helped me target the areas I wanted to treat without too much hassle. Within a few days, I started to see the weeds wilting, which was such a relief! I loved that it not only killed the weeds but also helped prevent new growth for a while. One thing I appreciated was that it didn’t have a strong chemical smell, which is always a plus when you're working in your yard. It definitely made my gardening chores easier, and I’m more confident about keeping my flower beds looking nice now that I have a reliable solution for those pesky weeds. If you’re dealing with a weed problem, I’d recommend giving Roundup Dual Action 365 a try. Just be sure to keep it away from any plants you want to keep! Overall, I’m quite happy with the results.
