Lawn Nuts,
I have blotches of a different type of grass popping up all over my yard (picture attached) the past several years and they seem to be getting bigger every year. Does anybody know what they are and the best way to remove/kill them so I can put normal grass seed down and get my entire lawn all the same type again?
Thanks!

Very interesting looking. Cannot say I have ever seen that before, but wondering what it could be? Almost looks like perhaps you have a fungus or something vs different breed of grass growing?
Ya that’s a new one for me too. Maybe check the soil underneath to see if you can spot anything unusual.
Can you take a closer picture of it before you mow? Likely one of the weeds in the background or a more dominant fescue is taking over.
Does a standard weed killer like Ortho Weedclear do anything to it?
I need to mow later today and will get a closer picture beforehand…
My guess would be Quack Grass. Best thing would be to kill it otherwise it will take over
I have never seen quack grass or crab grass look like that. Generally it grows much faster than regular grass. This just looks weird which makes me think he has a soil issue or some infestation like mold or other fungus.

oh I have those courtesy of our Cavapoo puppy…just not visible in that picture… 
Just throwing this out there, but I bet its a green sunfish.

yeah, not thinking its Quack grass as it doesn’t get much taller than in the picture…i’ll pull some of the blades up in a closer picture later today, its a very soft type of grass to the touch…
Very interesting Joe!

yeah, i’m clueless…only yard treatment I use is Melorganite applications 3 times a season…
It’s rough bluegrass. If your lawn is too wet (this year it is) then it can spread. It doesnt like dry conditions, at least compared to normal kentucky bluegrass. I gave up removing it since it seems to choke off my other weeds and I’d rather spend time fishing than taking care of my lawn anymore. I tried pulling/shoveling it out but that didn’t remove it completely. Glyphosate might be better to eliminate it.

Good info rootwo! I googled it and I found this info you could possibly check Joe to determine if it is indeed what he is saying: One way to distinguish them is to examine the root structures: rough bluegrass has stolons (above ground) and Kentucky bluegrass has rhizomes (below ground). Another way to distinguish between them is that rough bluegrass has a long, pointed membranous ligule and Kentucky bluegrass has a short, even membranous ligule.

Thanks all!
I have this same thing and only pops up on mole mounds / gopher hills after I take them out. It grows faster on the exposed dirt than your regular grass and the round circles are the result for me.

I have a feature on my phone called Lens, take a picture and let Lens search what it is
Not sure if it will work but worth a try
I think we narrowed it down to Rough Bluegrass…I just wanted to post a picture of it close up…
The other culprit that came to mind is creeping bentgrass.

Northern California Sensemilia. The amazing stuff about this is, that you can play 36 holes on it in the afternoon, take it home and just get stoned to the bejeezus-belt that night on this stuff.
Good call Mr. Spackler…
