Northeast corner of yard. Had heavy poa in this area too, most of that is gone now.

It is very bluish, and has spread and taken over. Very thick.

Possibly Nimblewill based on the look and time of year. Check for the telltale bumpy stems/stolons.
If that's what it is, Nimblewill is a non-turf-type (wild) warm-season grass. It's too bad it can't be made to work alongside cool-season grasses better in low-input conditions, as it would make a good cool/warm-season mix. But it tends to take over during drought stress, so it's not a good team player.

Is the spot shaded?

 

[Jconnelly6b]

@Turfguy93 Yes right now morning shade. There was a big cherry tree cut down this spring that was giving 70% shade in previous years. It was around last year too not nearly as bad

 

[Jconnelly6b]

@Green I don't feel any bumps on the stems. It's not clumpy either, as the descriptions I read said it grew in clumps.

It's growing more even like a carpet. Kind of hard to describe.

I sprayed with a CCO + Tenacity mix as I had some clover to knock out as well. Sprayed it on Monday 6/11. Hopefully it is nimblewill and the Tenacity will kill.

Try to look at all the features(auricles, collar). All I could see is one that looks like a boat shape tip.

Did you by any chance drop something here? Like a lot of Milo?

 

[Turfguy93]

My first thought with the spaghetti stolons was triv if it was shaded

I'm with Turfguy and think that has all the signs of Triv. A lot of people think it's neon green and easy to spot but that's not always the case. See how deep the root system goes and how hard it is to pull it. If it pulls up like carpet I'd say it's triv.

 

[Jconnelly6b]

@g-man didn't drop anything. I now think it may even be 2 different grasses.

One is bleach white after the tenacity a week ago and a couple 85+ days in a row.




The other just looks weak, but not bleached

Sure looks like nimblewill or possibly creeping bentgrass. The bluish color you describe makes me think it even more. NC State recommends topramezone for nimblewill ($$$$). Tenacity should get it if it's bentgrass (multiple apps).

I'd try the tenacity or tenacity / triclopyr tank mix at two week intervals, three applications. If that doesn't work, it will be very close to seeding time so you can just gly it and reseed, or hold on to your wallet and pop for the Pylex.

Grass Id is hard. There are similar ones and even having them in front of me, it could be a challenge. I still think it will be best to take images of the leaf detail. Go to this website and look at each of the images and try to find a match for each one. Once you narrow it down, then post the images of the most likely ones.

I experienced a few areas in my backyard that had been spreading since we moved into the house a few years ago, looked identical to your pictures. Did three apps of tenacity and toasted it, still have some smaller areas here and there to follow up on this year. I believe that it was creeping bentgrass. The morning dew made it really stand out with a light blue coloring.

 

[Jconnelly6b]

Here are some close ups and a recent picture of it in the lawn. Probably will hit it with another app of Tenacity tomorrow evening.

Uh oh. Now that sure does look like bermuda to me.

 

[g-man]

I dont think it could be bermuda. It has a ligule. It fits closer to orchardgrass, but I'm not sure.

 

[Jconnelly6b]

Does Bermuda get bleached by Tenacity?

 

[Delmarva Keith]

Does Bermuda get bleached by Tenacity?

Yes.

 

[g-man]

I think so. Any grass will get bleached if the rate is too high.

 

[social port]

I'm not sure either, but if forced, I would say that it is not bermuda.

I have this exact same grassy weed in my backyard. Treated it with Tenacity last year but will need to treat again this year. I've always assumed it was Creeping Bentgrass, but now am second guessing myself. Would a local co-op identify this? What's the best route for doing that? I hate to throw something at it (Tenacity) that isn't the best choice.
