Roundup For Lawns2 Concentrate (Northern) - 32 oz., Lawn Safe Weed Killer For Northern Lawns, Kills Crabgrass, Dandelion, Clover & Yellow Nutsedge, Starts Working Immediately, 5008710

I had tall fish skew in my yard. I'm mixed around up and sprayed it. And now they're all dead, I worked wonderful. You just have to recede afterward.

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.

Works good overall but not on all types of crab grass.

Three years ago dug up my old "lawn" and planted plugs of red fescue as a no-mow, drought tolerant replacement. Late this past fall I over-seeded the area to get it to fill in more, but red fescue grows very slowly from seed. Bur clover started coming up but I was concerned about using an herbicide on fresh fescue so I held off, and before I knew it that bur clover had just taken off and was everywhere, thanks to the previous "lawn" having been nothing but mowed weeds for years. There was too much to even consider manual methods of abatement, and too much for spot treatment, so I bit the bullet, purchase a hose-end sprayer, sprayed this product and hoped for the best. Having read a few reviews that said this product killed the weeds *and* the lawn, I was worried that my hard work with the fescue would whither up and die with the clover. Not so! This product worked fantastically, exactly as the manufacturer claimed. My fescue wasn't effected and the clover is dead and ready for removal. Applying this with a hose-end spreader was insanely fast and easy, and I've just purchased another bottle because I think this battle will go on for years until all the old clover seed has terminated and been killed off. I'll also be applying a pre-emergent when the time's right. Great stuff!

Worked okay on some clover and not at all on others. Worked okay on nutsedge, but not as well as some dedicated nutsedge products I’ve used. Very little response on wild violets, even with second application with spot treatment at a stronger mixture. I used the product under idea conditions, with no rain or water for at least two days after application. Not worth my time to request a refund, but would not purchase this product again.

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

Got Field Bindweed in the backyard, not crazy amount, but it is spreading. My kid and I have been pulling the sprouts on weekly bases, but each week we see the same amount grow back and some, finally declared losing the battle and turn to chemical for help. Talked to few master gardeners and few suggested to use Roundup for it, but only to apply on the leafs of the weed, not spraying all over. So I followed directions, let Bindweed grow till it's about to flower, dilute it to the right amount, take a tiny paint brush , hold the Bindweed vine in the palm(with rubber glove) and brush Roundup on the leafs one by one. Took me couple of hours (and a week of backache) to apply the first time, a week later, all the Bindweed has turned yellow and died. There was ZERO bindweed in the yard for almost a month, then few re-surfaced, applied Roundup again in the same way. It has been 5 months, and I have applied total about 4 times, each time is less than the previous. I think I have won.

I did not use a pre-emergent this year and have a lot of crabgrass and a few weeds. There are a number of good weedkillers (i.e., Gordon's Trimec) available but I have not yet found one that works well on developed crabgrass. I've tried products from Bayer and Ortho and others with very limited, or no success. I applied this product as directed and there are noticeable results on the crabgrass. It didn't do miracles but it does a better job of killing than the others. I will do a second application this weekend and expect continued results. This is the best product I've found yet for dealing with growing crabgrass. A note of caution: do not over apply or you will see some minor damage to the normal grass.
