These stalks have grown an inch in less than 24hrs. Significantly lighter shade than my PRG/KBG lawn. Different grass type or is it nutsedge? Been like this since early May where we had a really mild Spring. Thought it might be premature for nutsedge emergence.

It sucks. I have it too. Not sure if it’s Johnson grass or quack grass. It’s not crabgrass. Just annoying and I wish all my grass was the same but I’m starting to realize that’s not going to happen. Good luck!
One way to determine if it is nutsedge might Be to grab a strand or two that looks different from the rest and compare the root structure/ how it pulls out compared to a small handful of kbg- in my experience the nutsedge would come out easily in comparison and you can almost get a full mini root system from a single strand occasionally. A fist full of strong kbg is like grabbing someone by the shirt and trying to rip it off
I bought some generic grass seed from the dollar store and have this same problem 😅
It’s nutsedge. Sedgehammer will knock it out.
Ugh, I have this devil, too! It grows ten times faster than the rest of the lawn and has spread like wildfire. Scott’s Weed and Feed and pre-emergent crabgrass killer didn’t prevent it.
Probably nutsedge. Need a closer photo to be sure, but pull one at the root. Should come up really easily. Easiest way to distinguish nutsedge from other grassy weeds is the noticeable midrib. You should be able to see it running down the blade centerline and feel it with your fingers.
Has anyone ever seeded a full nutsedge lawn before? Would be interesting to see
Quackgrass.
This is a very helpful thread. I’ve gathered that it is either nutsedge, kbg, quackgrass, Johnson grass, or rye.
This is half my yard 😥
Brown Millet.
I’ve had the same problem for two years. Followed this thread the entire time. Can’t seem to get a straight answer on if it’s nutsedge or not. Tried sedgehammer twice and it didn’t work. Good luck.
I’m by no means an expert, but I have a hard time believing it’s nutsedge that’s been around since May. We’d need better pictures up close to see the details of the veining of the blades, etc. to be able to tell better what it is.
I have the same thing on our lawn but its right in a patch where I seeded a dirt patch. It all grew in then i mowed and the next morning it was grown higher than the rest.
Where is this from?
Did you happen to use straw?
Milo has this problem too, so I’m following for any other suggestion
Tenacity should kill those quack grass.
Check this site.

Orchard grass, I have it too
Tenacity can help but never fully kills it all. In the fall just kill it with Roundup and overseed after that. Repeat spring and fall till it’s gone
I probably have 7 different types of grass in my lawn, certain,y see the different shades of green and heights, . Forever repairing dog wee burns and grab any old grass seed box on the cheap.
Looks like you need to sharpen your blades big dog.
I’m not convinced it’s Nutsedge. Nutsedge doesn’t tend to allow such a clean cut like these plants have, from my experience.
But here’s the deal, for OP and everyone else in these comments battling similar issues and unsure if they are dealing with a sedge. You need to remember this whenever dealing with sedges, SEDGES HAVE EDGES! So the easiest and most sure fire way to identify them is to pull the plant out of the ground at the base, and then roll the stalk between your fingers. If the plant stalk rolls smoothly like a pen then you are NOT dealing with Nutsedge. However, if you can feel 3 distinct sides rolling between your fingers like a triangular pencil, then you ARE in fact dealing with Nutsedge.
Hopefully this helps y’all ID it better and stop wasting time spraying herbicides solely on a hunch!
Enjoy your quackgrass lawn. Or Reno
Nutsedge a big deal
Nutsedge. Very easy to manage. Ortho has a good nutsedge killer
Uhoh
How new is that lawn? Any chance you can get a better picture of the plant itself, maybe pluck
One out as deep as you can get? I’m not convinced it’s nutsedge yet
Side Note away from the problem grass type: You may want to sharpen your blade as a lot of grass looks more torn than cut.
Anual rye.
It doesn’t have the growth characteristics of the nut sedge I’m used to.
I think that big ridge in the middle looks like the sedge i get idk what kind it is but if you pull one up if it has 3 leaf blades that come out the same spot then its sedge.
sedgehammer works might take a couple applications tho.
I live in Iowa and had a similar post to this. Had a fiber optic company tear up my yard and come back and reseed with their own product and top with straw blanket. Can’t seem to get rid of this stuff but haven’t tried nutsedge or a broadleaf post emergent yet because of the immature grass around it
Ive had pretty good success with vexus its a granular takes a little longer to kill it off but it kills the tuber and prevents it from coming back next year
Quack grass or Crab grass. Good luck.
Aids
Gosh, never seen so much ! But agree with the nutsedge suggestions. Every year I have to spot spray where it emerges. I’m hoping the day will come where it will never come again.
Yes, it is. You’re wrong. Sorry.
Looks like your lawn is flipping you off.
I had this same looking stuff. Sprayed a mix of crossbow and Empero (i also had some crab grass and clover to kill)
Two days and it’s browned and dying. Great stuff
Those are trilobal, hard to tell, but you can definitely see the three lobes on the first pic right at the bottom, on center. Nutsedge
ETA: Time to sharpen your lawnmower blades 😜
