## Description

Roundup For Lawns 3 is a formula that kills weeds, not the lawn! It controls over 250 common lawn weeds, roots and all, and is especially effective on hard-to-kill weeds such as crabgrass, dandelion, clover and yellow nutsedge (see label for best application times to kill weeds). The ready-to-spray applicator is great for broadcast application to your entire lawn and covers up to 5,000 square feet. This fast-acting formula starts killing on contact and kills weeds down to the root so they don't come back. In addition, its rainproof in as little as 3 hours! Roundup For Lawns 3 is a simple step towards a beautiful, weed free lawn. Roundup For Lawns 3 Ready-To-Spray works great on lawns, and even better in combination with Roundup Weed & Grass Killer Concentrate Plus to kill weeds in your non-lawn areas such as sidewalks, patios and driveways—for weed killing solutions all around your home.

Review: It did kill the crabgrass for me - So I know there are mixed reviews on this killing crabgrass. What I did is two applications at half rate one week apart. It seemed to worked very well for me
Review: Best product on the market I've found for getting rid of yellow nutsedge in my lawn - I've used several products on the market made for killing yellow nutsedge in my lawn. In my humble opinion this is the best product to get the job done. I highly recommend this product for ridding your lawn of this horrible weed. We've had tons of rain this spring and this weed had infested up to a third of my front yard. It is a very difficult weed to kill and spreads like crazy once it gets established in your lawn. The longer you wait to treat for it the more it spreads.

## Questions & Answers

**Q: what is the difference between Roundup for lawns and roundup for lawns2**
A: Roundup for Lawns#1 is “for Northern lawns” in a diluted ready-to-use 1.3 gal wand sprayer. RfL#2 is the same product but in a concentrate you must mix. RfL#3 is also same product in an in-between concentration that’s ready-to-use that in a hose-end sprayer bottle. It’s the same packaging for RfL#4,5,6 except that product is “for Southern Lawns.” The difference between Northern and Southern is the active ingredients in different types and amounts. 1,2,3,4,5,6 contain Dicamba and Sulentrazone. In addition, 1,2,3 contain 2,4-D and Penoxsulam while 4,5,6 contain MCPA and Quinclorac. They should publish a comparison chart but don’t so they’ve created a lot of unnecessary confusion.

**Q: will it kill bind weed**
A: I have been dealing with Bind Weed for years and nothing seemed to work (including original RoundUp). I can confirm that this does actually kill Bind Weed.

**Q: Can ready to spray be refilled?**
A: The Roundup For Lawns3 Ready-To-Spray bottle is unable to be reused or refilled.

**Q: will it kill quackgrass?**
A: Quackgrass is an actual species of grass unlike crab grass. Even though it is a nuisance plant, most herbicides won’t kill it. Only a regular weed and grass killer like glyphosate containing Original Roundup will work kill quackgrass.

### ⭐⭐⭐⭐⭐ It did kill the crabgrass for me
*by B***N on August 7, 2025*

So I know there are mixed reviews on this killing crabgrass. What I did is two applications at half rate one week apart. It seemed to worked very well for me

### ⭐⭐⭐⭐⭐ Best product on the market I've found for getting rid of yellow nutsedge in my lawn
*by B***Y on July 4, 2019*

I've used several products on the market made for killing yellow nutsedge in my lawn. In my humble opinion this is the best product to get the job done. I highly recommend this product for ridding your lawn of this horrible weed. We've had tons of rain this spring and this weed had infested up to a third of my front yard. It is a very difficult weed to kill and spreads like crazy once it gets established in your lawn. The longer you wait to treat for it the more it spreads.

### ⭐⭐⭐⭐ Really Works
*by E***V on June 8, 2022*

Works great on weeds in the lawn only. It's not like regular vegetation killing roundup where you see results instantly. Weeds will start to yellow after 3 days or so. They'll start dying off in about a week and then you'll notice after a few weeks how great your lawn is starting to look. You need to be patient with this stuff. Also, it's not meant to be used off the lawn. Don't spray in over weeds in rocks, cracks in sidewalks or driveways or on dirt in your garden...it won't work properly. Those weeds won't die and you'll be wasting your product and money. Read the instructions and buy the right version for the area you live in. Happy Weeding!!!
