Roundup For Lawns1

The product works as advertised on mature wide leaf grasses such as crabgrass. I just wish it was available in a concentrate suitable for the small residential pressure sprayers. I have 50 year old acre of lawn with a strong base of fescue and bluegrass but it has become overrun. I've used a few bottles so far and is working very well and will probably need a few more bottles. However I am not looking forward to treating an acre of land one manual hand squirt at a time. UPDATED: Three of the last four bottles I purchased arrived without the hand sprayer as shown in the photo on the side of the bottle. This did not affect me as I dump them into a pressure sprayer now, but I would be unhappy if I didn't have my own sprayer. I still think it's a great herbicide for the intended purpose but the (sometimes) attached hand sprayer is mediocre at best for larger areas.

Knocked the crabgrass out! Takes about 4 or 5 days to see everything turn white - and after a couple of weeks the crabgrass is simply gone.

I am revising my review of this product, but left the original below for comparison. I might have been a little hasty in my review by not allowing enough time to elapse for the product to work. Typically any sort of weed killer only takes 24 hours to begin showing its effects. With this in mind, after 48 hours I hadn't seen any effect from the Roundup Crabgrass destroyer. However, after three or four days I am beginning to see its effects. The areas that I sprayed are beginning to yellow and turn white. I have changed my rating from 1 star to 4 stars. Crabgrass is a problem in the midwest, and it's that time of year where if you don't get a handle on it, then it can easily take over your yard. Even as a lawn "enthusiast" who goes through all the stages of treatment throughout the year, the crabgrass has been especially bad. I was hoping that a product labeled "crabgrass destroyer" was going to be the solution, but alas, this product did absolutely ZERO in killing crabgrass. Surely Roundup isn't lying to us with their advertising. Hmmm.

This is the only product I have found that kills all the problem grasses. I didn't understand why I was spraying for crabgrass and nothing was happening. I discovered I had goosegrass and johnson grass along with crabgrass. You need to be patient with this product. Once you spray it might take 2 to even 3 weeks before the product works. The invasive grasses will slowly turn white then brown and eventually disappear. The total time is about a month from spraying. In the beginning, I kept spraying every week and was just wasting product by not allowing it time to work.

I don’t usually write reviews but this is necessary. I should’ve taken before and after pics but I honestly didn’t have high hopes. We had one of those yards that’s covered in dandelions and ugly weeds. I mean COVERED. I ordered this product after reading some good reviews. I made sure to use it when I knew it wouldn’t rain for a few days and when the wind wasn’t bad. Directions say not to apply to freshly cut grass as it needs the entire weed to help soak in. So while the grass was long enough (to the point that it should’ve been cut) I sprayed it entirely over my yard. I mean every inch of the yard I soaked, paying special attention to the really large weeds. The bottle and sprayer were very easy to use. After spraying, we waited. Within 3 days, all the dandelions and weeds looked dried up and wiggly. We mowed the lawn and BAM. NOT ONE DANDELION HAS GROWN UP. I am amazed. We did have to go in a second time to get some smaller weeds that popped back up, but compared to what our yard looked like before (a literal dandelion field) this was nothing. 100000% recommend this product to anyone needing to get rid of dandelions and other yard weeds without destroying your grass. Very affordable and very easy to use!

I think this is a very useful product for when you don’t want to spend all week pulling weeds. It doesn’t kill 100% of weeds, with some weeds being more resilient than others. But it kills a lot of them. The included automatic spread nozzle also makes the process as easy as can be. The nozzle itself has three selections: stream, spread, and spray. Some people complain that this product kills their grass, but I’ll have you consider this. Weeds kill grass. Aside from being unsightly, that’s a big part of why we bother to get rid of them. When you kill the weeds, of course you’re going to see the remaining dead grass. Is this stuff good for grass? No. But does it kill your grass? No. So use this product without worry, and to save your back from bending over for hours to pick individual weeds.

The product likely works fine due to the active ingredient, but I wanted to highlight something not obvious to me. Pull the red connector at the bottom of the spray handle to extend the applicator hose

It works to a degree, although it is not 100% effective. I have had to spray some areas twice and today when I mowed the yard, I see that some are still hanging on. I will say this, it has weed killing power without some of the lawn stunning side effects that regular 24D has. Afraid to go back the third time as the weeds might become resistant. But with-it being Roundup, and being able to use it on the lawn is pretty amazing in and of itself
