Ratings & Reviews for Roundup Super Concentrate 0.5-Gallon (s) Concentrated Weed and Grass Killer

Didn’t work

I followed the directions exactly and it didn’t work. I turned over my garden and wanted to plant turnip and mustard greens, but I had a layer of nutsedge come up. I sprayed it with a pump up sprayer and although the nutsedge showed splotches of yellow, two weeks later it rained and it all turned back green again.

A question about using Roundup in flowerpots

I have used Roundup for years but as I get older I have begun to plant more annuals and other plants in larger pots. can I use a spray bottle with diluted Roundup to spray small but prolific weeds in those pots being careful to block spray from getting on my flower plant. I have used it in my flower gardens for a long time with no problems as long as there is no wind and I don’t get close to my plants.

Keeps the weeds and grass away for a year

We have a small farm with a very long, and large, gravel driveway. We use this once a year to control grasses and weeds that grow in the gravel driveway as well as controlling grasses around our barn, under our trees, and on the sidewalks. This also knocked out poison ivy in a few spots if applied thick enough. Combined with a Stihl backpack sprayer, we couldn’t be happier. For mixing, add water slowly as others have suggested. It will foam with fast water flow and can overspill if not careful. ...

No good

Tried the super concentrate instead of the regular concentrate. Waste of money to me 4 days later and seemingly no effect Won’t buy again

Disappointing Results

Bought this last week. Sprayed my existing lawn 3 days ago. So far it looks like I have not sprayed it. Very disappointed

Instructions are stuck together.

It’s easy for the instructions to get destroyed in Chicago humidity. Who do I call when I have time to use this on a Sun afternoon

The Only Weed-killer Product

Roundup has been the only consistent weed-killer on the market. I've tried other manufactures with mixed results, but Roundup was the only consistent one. Since I live in California, I will not be surprised that it will be banned. I would like to add that our heart goes out to the suffers as a result of Glyphosate use.I am hoping that further research is conducted.

Totally Ineffective

Spent hours spraying several gallons of the mix in the right proportion and the weeds now look well watered and healthy after 4 days. The website says effective in 1 day, the label says 3 days and Kaitlyn from the chat line says visible in 7 to 14 days and only effective after a month.

Does what it says it does.

[This review was collected as part of a promotion.] Roundup has been around for a while and has proven itself to work again and again. This formula does work as specified, but around prized plants that you don't want harmed, be sure you are a good shot to get only the weed. I also like that it comes with a measuring cup.

Works quickly

[This review was collected as part of a promotion.] Kills weeds quicker than other brands. Easy to measure and mix. Haven't found a weed this stuff won't get rid of.

easy to use

[This review was collected as part of a promotion.] Very easy to use. Simple directions. It works effectively for what it is to be used for.

Weed and grass killer in a concentrate bottle

[This review was collected as part of a promotion.] I got this concentrate Roundup product to treat weeds and some grass that is overgrowing around my flower bed. Being a concentrate product, it means you need to mix this with water before use. I always like concentrate product because you will get more application compare to ready to use products. I mix this Roundup concentrate with water in a tank sprayer. Just followed the instructions found in the guide on the back of the bottle. For...

You get what you pay for.

[This review was collected as part of a promotion.] Roundup works and works well If you need help around your landscaping, then this product will cut hours off your work schedule. Less mowing less frustration. Just make two applications. 1st application to remove vegetation currently growing, then second application AFTER existing seeds have started to grow. It’s that simple. It will save you time, money and frustration.

Works and saves you money!

[This review was collected as part of a promotion.] I use this to refill my roundup ready to spray container. That way I can continue to use the hand sprayer that makes it super easy to apply and by using the concentrate it saves money. Kill all the weeds and grass that are green. Takes about three days.
