Doesn't work
I mixed a little stronger than suggested as I've used it in the past and it didn't work
So I sprayed weeds waited 3 days. No change. Dandelions are still thriving. I sprayed everything a second time. Some weeds a turning yellow. Many are still green. Would not recommend this product!!

We're sorry to read about your disappointment with Roundup Weed & Grass Killer Concentrate Plus and appreciate your feedback.
A complete kill will take 4 weeks. Apply when daytime temperatures are consistently between 60 - 85 degrees F. If there is a lack of rain fall or water then weeds are not actively growing. Water the area 24hrs prior to applying roundup or apply a day or two after it has rained for best results. Evening applications will take longer to kill the weeds because the plant is no longer photosynthesizing. Best to apply in morning after dew has evaporated. We recommend that weeds not be cut for two days both before and after the product application to maximize leaf surface and absorption. Reapply 7 days after initial application, especially on viney, woody or waxy plants.
We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please reach out to us at 877-220-3089 if we can further assist.

Good stuff!
Killed the weeds dead. They started looking weak within a couple of hours and then laid over a couple of days later.

Stars are only for product effectiveness. But what a scam....
Stars are only for product effectiveness. But what a scam. My old Roundup bottle contained 36.8 ounces and was labeled “Value Size”. The bottle I purchased yesterday is the same bottle and contains 35.2 ounces. Nonetheless corporate megalith Bayer labeled it “Larger Size”. If Bayer can’t do simple math why should I trust their aspirin? Truth in advertising?

Great Product
[This review was collected as part of a promotion.] This concentrated plus Roundup pesticide killer is very effective controlling all unwanted weed and grass that grows in not desired areas. It is simple to use just by mixing 6oz to one gallon of water, the product came with a measuring lid to make the job easier. It takes at least 24 hours or more to see results. After using this product I can say that is effective and won’t harm pets or peoples skin, just follow instructions provided on back of the product for proper use and storage recommendations. The Roundup Concentrate Plus Weed and Grass Killer performs well and as expected.

Deader than a door nail
[This review was collected as part of a promotion.] I have used Roundup products for years. As you will see from before and after photos, it gets the job done. I just found my target and even used a Roundup sprayer which targeted my prey very accurately.

Very effective
[This review was collected as part of a promotion.] Roundup Weed and Grass Killer is fast and effective! Literally overnight I saw amazing results out back where I fight tall water weeds. The smell is not noticable and it's super easy to use, small enough to store anywhere and is of great value. Compared to other weed and grass killers, I prefer Roundup simply for it's fast results and ease of use. I definitely recommend and will repurchase.

Amazing
[This review was collected as part of a promotion.] I like that this bottle includes a small cup to help you measure to add the water with this product. This product helps your side to prevent any unwanted roots grow between the small cracks of the sidewalks.

Roundup is the way to go!
[This review was collected as part of a promotion.] I like the Roundup Concentrate Plus Weed and Grass Killer, 36.8 oz. It comes with an Easy Measure Cap. Just add 6 oz of concentrate to one gallon of water in your sprayer. I’ve definitely noticed an improvement in my lawn. No more weeds! Roundup is a brand I trust to get the job done. Definitely recommend.

Effective liquid and fast results
[This review was collected as part of a promotion.] This concentrated plus Roundup pesticide killer is very effective controlling all unwanted weed and grass that grows in not desired areas. It is simple to use just by mixing 6oz to one gallon of water, the product came with a measuring lid to make the job easier. An advantage is the value size of this bottle enough to cover all areas in my patio. The results are fast and notorious on the designated areas that product was applied in another 3 days. After using this product I can say that is effective and won’t harm pets or peoples skin, just follow instructions provided on back of the product for proper use and storage recommendations. My driveway and fence sides is clean and out of unwanted roots, it’s a product I absolutely recommend.

The Roundup Concentrate, a Killer
[This review was collected as part of a promotion.] The Roundup weed killer has been applied to an area with weeds, substantial in numbers as well as size.
After two days it was obvious that the product was at work. See enclosed photo.
The Roundup Concentrate Plus Weed and Grass Killer performs well and as expected.
The concentrate was easy to mix with the measuring cup on top of the bottle.

Very easy to use
[This review was collected as part of a promotion.] I absolutely love how easy it is to use. I poured a cap full into my spray container and filled the rest with water. I sprayed my fence area and my driveway area. I don’t think it worked the first time due to rain coming in within the 30 minutes of me spraying it. Overall; very easy to use and concentrate it.

Zenith Zoysia new lawn (one year)
[This review was collected as part of a promotion.] This is a product that I have been using for a long time.
There are others that try to copy the performance, although less expensive, not as effective. I have had it for all types of grass and weeds and found it to be super effective with my front lawn which is bermuda. I am having a few issues, which I cannot identify, with my new zoysia. They say it might be more of a fungus than the application of the Scott's product.

Fantastic results
[This review was collected as part of a promotion.] I have a patch of weeds in my backyard that have been so resistant to other weed killers I have tried. This is the first weed killer that has got to the “root of the problem”
I will not buy anything else at this point. I have added a photo and as you can see, all my horrible crabgrass and weeds have been obliterated

Excellent Weed and Grass Killer
[This review was collected as part of a promotion.] This product works well. I utilized it to clear some weeds and crab grass from the front of your property and as shown in the attached picture is did an excellent job. I applied it with a pump sprayer and applied it on a calm day so as to not spread it where I didn't want it. I saw the effects of the application within about four hours and the next day the weeds and crab grass where dead.

Round Up saves the day again!
[This review was collected as part of a promotion.] Round Up is my all time go to weed killer. I can count on it time and time again.
It always kills the toughest weeds and gets all the way to the root.
The best part is I can get super close to plants I want to thrive and it doesn’t harm them.
I recently had some creeper weeds super close to my roses and Round Up saved the day in just one application.
It’s so easy to use too! The directions are clear and simple.
If you haven’t tried it, definitely grab some.

Roundup- a must have for homeowners
[This review was collected as part of a promotion.] If you own a home, you need Roundup on hand. I've used Roundup for as long as I can remember. Absolutely never use it on weeds that are in the grass; it will kill the grass. The place to use this is for weeds in concrete expansion joints, in rocks, and so forth. I also use Roundup to kill grass that has crept into mulched beds, but use it sparingly so you don't kill flowers or trees; mist it on well away from plants and trees.

Kills Weeds Fast!!
[This review was collected as part of a promotion.] Our concrete sidewalk is currently got weeds everywhere, the weed and grass killer comes in handy. My husband always pre-mix it with water, since it’s a concentrate plus. He will spray the weeds and within 12 hours you can see results that the weeds are dying out. Definitely recommend if your looking to kill weeds.

Simple, Easy, Effective, Economical
[This review was collected as part of a promotion.] I live in suburb of Houston Texas.
Weather conditions during applications were hot (90’s) and dry.
Mixed 1.5 oz / 32oz spray bottle.
Sprayed weeds in drive way and various bed locations.
All weeds shrived up and died in 1-2 days.

This is the best product for my landscaping needs
[This review was collected as part of a promotion.] I sprayed the ROUNDUP Concentrate on my entire back lawn under the trampoline and within two weeks all the weeds were gone. This product is efficient and produces results as long as you follow the instructions on the back. I would totally recommend this product to anyone.

Quality Killer of Weeds/Noxious grasses and Vines.
[This review was collected as part of a promotion.] Excellent at killing root vines, poison ivy, and other noxious weeds that are growing in my back yard. I've tried other products but this does the best, even weeds growing in the concrete cracks in my driveway. I use gloves and never spray when it is windy out. Works best on hot days when the product gets absorbed into the leaves of the target weeds and vines. Mix with water into a hand pump sprayer following directions.

Does what it says
[This review was collected as part of a promotion.] The Roundup weed & grass killer exceeded my expectations , I used this around and on my fence. Living in Florida weeds seem like they grow overnight and this was perfect. Within a few days all the weeds along my fence was dead , i highly recommend using this .

It does the job!
[This review was collected as part of a promotion.] I’ve used Roundup Weed & Grass Killer for many years and have always gotten the expected results. Using the 36.8 oz. size and following the 6 oz. of concentrate per gallon of water should produce just over 6 gallons of spray. I confess to using 7 oz. per gallon, so I don’t quite get that much but that’s my fault, not the Monsanto Company. I learned that Roundup – Ready to use has a faster acting formula than the Roundup Concentrate Plus Weed & Grass Killer, so I don’t expect to see significant results sooner than 2-3 days after spraying.
For this evaluation, I chose a very overgrown spot with lots of different weeds. As the pictures indicate, it’s taking quite a while to totally kill the plants in the area. The FastAct® Technology that is touted in the description must not have been put in the bottle that I have because I didn’t really notice much difference in the first 9 hours. After 3 days, I’ve seen some results but with the size of the weeds, I’m expecting it to take much longer. On day 10, I’m ready to string trim because all the weeds are dead.
Roundup ultimately produced the expected results, you just need to be patient.

Used to work fine, now its just watter
It used to work fine killing the weeds and grass in few minutes. Now one day after applying it looks like I just watered the weeds. And of course I used and followed all instructions on label correctly. What is happening roundup?

Works fast but doesn't finish the job.
I've been using a generic, Farm Works, for years. Problem was it took days to show signs of dying but, after about a week the weeds died & shriveled up completely.
The Roundup shows signs of killing within a day but, even after a week there was still fresh green roots.
I had to reapply today because they were still alive & new weeds were coming up.
For the high cost of this product, it's not worth the money. Maybe if you've got tiny, spotty weeds it's ok but, if you have a lot of heavy growth it'll take several applications.
I'm going back to them generic brand. No

We hate to hear that you did not enjoy your experience with Roundup Weed and Grass Killer Concentrate Plus. Visible results occur within 24-48 hours after application, with a complete kill in 4 weeks. A lower dilution rate (3oz per gallon) will not be as effective as the higher dilution rate (6 oz.), especially on perennial weeds. Apply when daytime temperatures are consistently between 60 - 85 degrees F. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience, please call 877-220-3089 for assistance. When calling, please refer to this review.

Excellent product!
I've used this product for several years and it always works as advertised. I use a plastic 2 gallon sprayer with an attached wand. I always put water in the sprayer before adding the concentrate. The red measuring cup is handy and clips onto the bottle. I spray the grass on my driveway which is both gravel and concrete, Making sure it is sunny and at least 70 degrees, with NO wind. After about an hour, I can see the leaves of the weeds and grass wilting. They are completely dead in a couple of days. No grass or weeds show up for several months.

Killed everything in the area as advertised. After clearing bed, topping off with material weed barrier and mulch, weeds are popping up after just 2 weeks!
