“First time poster long time lurker. This weed/grass is taking over my lawn. Can anyone help me identify it and how to get rid of it. submitted by /u/andresc2 [link] [comments]”
“I live in zone 6a ohio and need help finding the best herbicide to kill the weeds in my lawn without killing my lawn. The most prevalent weed in my yard is white clover, followed by creeping charlie, dandelion, crab grass, nutsedge, and broadleaf plantain. I also included an image of a weed i can't identify. I still have enough grass to stop me from nuking the whole yard but want to take care of the weeds throughout the yard before seeding. I'm looking for a herbicide that can take care”
“What is this popping up in the turf this summer? Zone 6b central Indiana. Initial guess is maybe Bermuda based on it spreading pretty quickly, and only appearing once it got hot mid July. If it’s a weed, is there anything to kill it? Already sprayed tenacity and triclopyr earlier this season and it came up nonetheless. About to apply tzone before overseed. submitted by /u/PainterOtherwise7849 [link] [comments]”
Looks like nutsedge to me. If it is, then Sedgehammer or Sedgehammer+.
“Nutsedge. Use sedgehammer . Will kill the nut sedge won't hurt the grass. May need more than one application this season”
“Anyone know what these weeds are and what I should do to eliminate them? Every time I cut the grass they always grow faster than the grass and look bad. Located in SW Ohio. Thanks! submitted by /u/Massive_Tune2480 [link] [comments]”
It’s taller/faster growing, lighter green, and a wider blade than the kbg.
“Northern Nevada location. This grass keep popping up and looks like it’s taking over. Normal grass around here is fescue. submitted by /u/UBWine [link] [comments]”
“Hey everyone, I live in southeast Wisconsin and have been in my house a couple years. I have been battling these tufts of grass(?) in my garden beds. Does anyone have any thoughts what it is? I’ve dug them out before and don’t seem to have runners underground. When I pull by hand, they come out relatively easy but don’t know if I’m getting the entire root. I’ve sprayed with Fusilade II but didn’t do much to it. Any suggestions would be really appreciated! submitted by /u/StefanMan4 [”
“For me it’s usually 3 to fully kill it. Depends on how active it is though, the more active the better. Some weaker patches can be knocked out in a single app”
“It pulls up really easy with a shallow root ball. Is this something I should just hand weed? Or is there a slick chemical solution? submitted by /u/No_Boysenberry_6989 [link] [comments]”
“Another one of these posts This plant has been spreading across my yard for the past couple of years. Please help me with obliterating it. My phone is suggesting Mallow. Accurate? Best strategy for elimination? submitted by /u/im_a_good_lil_cow [link] [comments]”
“Can someone help identifying this and what to use to stop the spread? I have missed the early spring pre emergent. but I now have a company that does the chemical and have visited 3 times so far since may. The person from that company said this is goose grass. Online and AI searches have been all over the place, nutsedge to crabgrass. Whatever he applied doesn't seem to stop this and various other weeds on my lawn, including crabgrass along the edges of sidewalk/driveway. My lawn is a B”

“Good. I mean, honestly, I'm not sure why we don't have some infographics about the most common weeds pinned in this subreddit. Maybe the mods should consider that, I'd be down to put some together.”
“Area: Tulsa, OK :: 7b My lawn is the typical Bermuda… and weeds. My friend gave me some stuff to spray for the weeds (not sure what it was) and it did a marvelous job with one spraying on everything except for one weed type in the front yard and another on the side and in the back. The first 2 pics (assuming they show up in the order I selected them) are of the front and the others are the side/back. Looking at pics in this sub, one might be Johnson and the other Nutsedge? I don’t mind going nuc”
“I'm looking for some confirmation on Identifying this weed. I am in central Alabama and have what used to be a pretty decent lawn until the last few weeks. This weed has slowly taken over the parkways and is starting to sprout all over the lawn. I am pretty sure it's dove weed. I originally assumed it to be carpet grass but after pulling some out and having a conversation with ChatGPT, Claude and Gemini it's led me down the path of dove weed. I think Celsius should take care of it af”
“I thought that this might be nutsedge. I decided to dig it up from my dry flower beds, but I didn't see any nuts. What is it? submitted by /u/buttgers [link] [comments]”
“Does anyone know what grass or weed this thick blades stuff is? It’s a deep blue green. When I lightly rake these areas, individual plants like the ones in the pictures come up super easily. Minneapolis mn area. Lawn is mostly an elite twin city seed KBG blend. submitted by /u/TyNoPwNs [link] [comments]”
“First time posting. Love the grass in my lawn. Can’t figure out what it is. Haven’t seen it elsewhere. Super soft and vibrant green. Ai couldn’t tell me either… Southwest Ohio. Hoping to figure out what it is so I can make sure to keep it this grass. TIA. submitted by /u/Slow-Moose-9961 [link] [comments]”
“Southern Maine. I have a nice section of lawn with actual turf grass on the other side of my driveway and it just popped up over there too. Need to identify it and destroy it! I hope its not toad flax like Google says! submitted by /u/OfreakNwoW1 [link] [comments]”
“Pull the runners out of the lawn without removing the roots. Put a couple of piece of cardboard under the runner. Out concentrated glyphosate on it. Let it dry. Move on to the next one”
“Yeah that sounds right. Probably wait a month or so before a second application if needed”
“Why does everyone in this sub call every grass crabgrass? I’m perplexed about this. This does look like Dallisgrass to me.”
“Can anyone identify this grass in my lawn? I overseeded last year with kbg and tall fescue mix from twin city. I need to do some spraying for weeds which will include tenacity (for some bentgrass and quack grass at the edges of my yard) and t zone se (for a bunch of different broad leaf weeds). If I can get rid of this thick grass too, that would be great. submitted by /u/Bengthedog [link] [comments]”
“I once thought this was nutsedge, I no longer believe that to be the case and I am not sure what it is or how I should kill that which is not identified. AI is not a seasoned enough lawn care warrior, so I turn to you all, the experts of striped lawns, for help. (Zone 8b/Southern Coastal VA) I have some good crab grass patches with this stuff mixed in. I plan to overseed my bermuda with rye in the fall and then use a pre-emergent in the spring, but I would like to start this week with killing th”

“Does anyone know what kind of weeds these are? I have bermuda grass in poor shape which i will revive. Was thinking of using this weed and feed: https://bioadvanced.com/5-in-1-weed-and-feed.html?utm_source=chatgpt.com and water weekly to try and bring back all of this.Thanks! submitted by /u/ryanisnottrue [link] [comments]”
“Upstate NY, Rochester area. Over the last two weeks this plant has exploded and started taking over. Any advice on what you think it is and best product to target it with? So far it hasn't spread to the side yard yet; but the property next to me is made of this stuff. Edit you guys are the best - thank you so much! submitted by /u/Fittir [link] [comments]”

“Battling these two odd ducks in the lawn. What are they? Is there any way to kill with selective products or just pull by hand and reseed over time? Central Indiana, zone 6b. Edit: not concerned with the bare patch - battled a bit of fungus earlier this summer. Also deal with lots of dear that seem to cause some burning. And dogs. submitted by /u/PainterOtherwise7849 [link] [comments]”
“I’m trying sedgehammer on a test sample first, based on mixed opinions of what the wee/grass is down in the comments. If it’s effective, I’ll be sure to post the update. If you also find a solution, please let me know. Our locations are so similar that we may be running into the same problem”
“Trying to figure out what type of grass I have. I bought the house a little more than a year ago and this fall i want to make improvements to the lawn as it’s several types of grass, weeds, and clover. Whatever this is, seems to be the majority up front and does well in the sun. Is it Bermuda? Is it a hybrid? It doesn’t seem to produce seed heads like I usually see when letting Bermuda go for a few weeks and it doesn’t seem to brown when cut short. These were taken at different times, so color m”
“Located in CT. I’ve noticed these small patches of grass popping up in a few places. Any idea what it is? AI doesn’t seem to be accurate after I google what it thinks. They have one super thin stem and then it kind of fans out into blades. Hopefully the pics are okay. Thank you! submitted by /u/_Dr-Tuna_ [link] [comments]”

“If the stems are triangular, nutsedge. Normally I’d say start pulling, but that looks pretty wide spread, you might want to look into chemicals. Pulling, you need to be constant and merciless or you will be dealing with it spreading for years. You can overcome the root’s ability to shoot up new leaves and starve it. Treatment like sedgehammer can kill it in a few weeks. Good luck”
“My wife and I got rid of a couple dying trees in our yard and the company that was supposed to level and match our grass must’ve used a mixed seed blend. As such, we have bright-green grass/weeds that are growing 3x as fast as the other grass and make the lawn look terrible. I’m sure this is not crabgrass, as we have a lawn company that comes out and takes care of that. I’ve also killed crabgrass myself in the past (before I got lazy and hired a company) and the grass/weed remains. Does anyone k”
“Ohio, zone 5A. I thought it was nutsedge but it's a darker green. Didn't have this last year and have tons of clumps all over the yard this year. Grows much faster than the other grass. Is it another weed or just a different type of grass? Best way to get rid of it? submitted by /u/Public-Mammoth-7604 [link] [comments]”

“I’m in zone 6b, planted some zoysia plugs in my lawn roughly 1 month ago. Been keeping an eye on weeds surrounding/between the plugs and today I noticed these sprouting at the base of some of the plugs on the outside edge. Is this what zoysia runners look like? Or are they just crabgrass that I can rip out? I was leaning towards crabgrass because of the purplish color submitted by /u/rajofthenee [link] [comments]”
“I have patches of this grass covering roughly 1/4 of my tttf/kbg lawn. They pulled out like carpet with shallow roots so I assumed this was bentgrass and have already applied tenacity twice, 2 weeks apart which helped marginally however was expecting better control at this point. Getting ready to applied a third app of tenacity however I am now second guessing whether this is indeed bentgrass and not poa triv. Anyone able to offer a second opinion? submitted by /u/dmdave12 [link] ”
“Have a couple areas in the backyard with this in it and it seems to be spreading. Clumping fescue doesn’t seem right for the temps in north Texas. I am not quite sure what it is. submitted by /u/FastmanGT [link] [comments]”
“That’s what my lawn looks like when the kbg is leaving the chat and the fescue is doing all the work for peak summer.”
“I want to reseed my lawn in some areas that have been taken over by weeds, but I’m not certain what type of grass I currently have (house is new to me). I’m on Cape Cod in Massachusetts. My lawn is the last to come in during the Spring but it the greenest lawn in the neighborhood and stays that way well after the other lawns have gone brown in the Fall.
