Since the blades are broad and it pulls easily I have found that purposely not mowing for two weeks (so it's poking up above the slower-growing grass), then using a power dethacher set at the very highest setting will pull all of it out, leaving the finer-leafed grass alone. Stiltgrass is an annual, and it goes to seed only once per year, and it won't come back from root fragments. There are its key weaknesses and they can be exploited. But mowing just makes it eventually go to seed down low. Dethatch in July, do it again for new germination in early September before it goes to seed. Anything that come up after that won't have time to go seed before the first hard frost kill it.

@@Tricia_JoElle I'm sure there are much better professional-quality units but I bought an electric (120V) SunJoe dethatcher. It comes with a tiller/scarifier blade installed, for scraping the soil for seed preparation, and the wire-tined dethatcher bar, which is the one you would swap in. Since I'm not trying to dethatch all the way to the ground during a stiltgrass pulling session I set it at the maximum possible height so it is barely touching the grass, but is snagging the stiltgrass blades. During the Summer session I don't the bag the thatch as the bag is tiny and must be emptied often. Rather, I just do some raking afterward and compost the stiltgrass. By October the stiltgrass will be going to seed so you'll have to bag and dispose of the stiltgrass, lest it re-seed your lawn. For the remaining stiltgrass in the woods that i missed, that is also going to seed; time to try to pull every one of them. Just one plant produces an insane number of seeds so it pays to be thorough. That's how this invasive species is taking over!

This has been the bane of my existence…i have 40 acres in NC and the neighboring property did a clear cut of hundreds of acres and im fighting this on every border….i had to go nuclear with imazapyr…and yes, i killed many trees in the process…ive got a commercial tank sprayer and brush trimmer that i have heavy string on…tried weed wacking before seed…it was fine until the next season…seedbank resprouted…plus all my neighbors property blowing seeds over…so i got permission from my neighbor to spray 40 feet into his property… The only thing that truly stops stilt grass is to kill the seedbank, that is a soil sterilizer….pramitol, ecomazapyr, imazapyr… I was like you and was trying to save native species but it became so counterproductive and expensive…on a large scale where your talking dozens of acres…did the whole acclaim route, 300 gallon sprayer takes 9000ml of acclaim, thats 2.5 gallons, thats $800 per treatment…and you need to do that twice….so…. Imazapyr is only $300 per 2.5 gallons and will kill the seed bank…kills everything I tried fighting the good fight but ran out of patience, money, time… Now i can replant the seedbank with native plants that can outcompete stiltgrass, annual grass/oats as a cover and i created a 40ft wide bare ground fire line between the property that i keep treating with imazapyr

We've all been there when one second, we're looking at a beautiful lawn just coming out of dormancy in April and the next there's a massive infestation of weeds! I downloaded PictureThis to identify what weeds I have in my lawn and found out I did indeed have a major Stiltgrass and Blue Violet infestation. Your tips on Acclaim application helped me knock it out and the lawn has been bouncing back. Thanks for uploading, subbed!

My understanding is that blue violets are important larval food plants for several butterflies and other valuable insects. People in the know are encouraging violets in their lawns (along with some other flowering plants) for just this reason--and not mowing until the larvae have developed. See Xerces Society and other similar organizations for more info.

It's 10/3 in NE, above Phila., so I'm going to spray the Acclaim Extra. I watched it spread slowly, and just kept cutting it. Unfortunately, it grows faster than grass, so by the time the grass needed cutting, the stiltgrass was high and THICK and the push mower would stall. Push mower. Not fun. Fed up, on a mission, SunJoe, Acclaim, and "enough of this" attitude! LOL! BTW, I ordered Acclaim from Amazon due to free shipping. and it came with an expiration date of 16 months ago. It'll weaken in strength by the time I use it all up. I also got a chemical that makes the Acclaim "stick" to the stiltgrass. I just heard you say "didn't do as good as I thought it would"> NOOOOO! I read to spray it when it is 6" high. At this point, astroturf is looking pretty good to me right now! Just kidding!

Amazing how fast stilt grass spreads. Have it every where I look now after first seeing it three years ago and spraying it. Couldn’t get at it this year as much as I was down with a bad case of shingles for seven weeks. It’s all through my lawn too. Seems like it pops up in patches where it never was before. Wondering if it root spreading or were there a bunch of seeds there?

@Broskibrother

I saw somewhere that you can do that, but if you consistently cut it low it will seed underneath that height. So you have to weed wack it when its tall late in the season before it seeds so it won't grow back in time. I wonder if weed wacking it straight to bare ground would work though.

I notice that Japanese Stiltgrass is not listed as a species controlled on the label, although it falls into the "annual and perennial grass" description. I would try some Acclaim Extra and see how it compares. Does your current approach not seem to be killing it, or it seems killed at the end of the season, but still comes back the next year? When are you treating it?

I believe The Woodland Steward explains he is trying to keep it out of his woodlands. He recognizes that standard lawn grass species are not native, but they are not super-invasive like the stiltgrass. If stiltgrass stayed in the lawn, it wouldn't be such a problem, but it spreads everywhere by seed. He mentions that his property has a relatively small amount of lawn that he wishes to keep.
