You may want to see if you can upload larger (full-size) photos.

Re: Invasive Grass Identification
Possibly a sedge. Nutsedge maybe. I get some sprouting this time of year and it looks similar.

Re: Invasive Grass Identification
I originally thought possibly nutsedge...but the stem is not triangular when I roll it in my fingers...the stem is basically round or oval...also, when I dug up the roots, they did not have any "nuts".

Re: Invasive Grass Identification
Worse actually. The URL wrappers just point to https://postimages.org/ rather than the image files. Always test your links when you post.
Please tell me that the color in those photos is not true to life. Even yellow nutsedge, which this isn't, isn't that fluorescent lime green.

Re: Invasive Grass Identification
Thank you for the feedback. On my phone when I preview my post before submitting (and when I look at the forum), the pics look good. My first post has smaller pictures, and my next post has larger pictures that fill my phone's entire screen. The pictures actually show...I do not have to click a link...the pics just show under my post. I will try from my laptop tonight. I am using https://postimages.org/ to create the links of my pics, and then I copy/paste that link into my post to show the pic. What method do you use to post pics?TimmyG wrote: ↑July 10th, 2019, 2:47 pmWorse actually. The URL wrappers just point to https://postimages.org/ rather than the image files.

And yes, the color in the photos is representative of the true-to-life color...your description of "fluorescent lime green" is very accurate.

Re: Invasive Grass Identification
I'm not referring to your "thumbnail" images, i.e., the small images included in your post. They're fine, albeit useless for ID. I'm referring to the fact that when you post images via postimage.org, clicking the thumbnail images should take us (and you) to the larger originals that you submitted via postimage.org. Originally, you're in-post images were quite small but as expected. However, clicking them opened images on postimage.org that were only 360x640 pixels. That's shameful. Your second attempt seems to have replaced the smaller thumbnails with the slightly larger images, but now there are no larger images to be seen on postimage.org. It's 2019. If you want to get help with grass ID, you need to get the original megapixel images uploaded to postimage.org and get the links functional.
How do you do that? I have no clue. I don't post images. But I do use a 46" monitor and have good (corrected) eyesight, so if I'm telling you that your images are too small...

Re: Invasive Grass Identification
Much better! If not for the color, I'd say this is just your run-of-the-mill large (hairy) crabgrass. Are you familiar enough with crabgrass to have ruled it out? Did you apply a pre-M this spring?

Re: Invasive Grass Identification
I also think it is crabgrass but wanted some confirmation. I have never done pre-M or fertilized, and the lawn is 23 years old (previously farm ground). Could the bright green be from lack of nitrogen?

Re: Invasive Grass Identification
Did it suddenly burst onto the scene in late June? Does it grow much faster than the overall lawn, especially when it is hot/dry? Does it prefer sunny areas?

Re: Invasive Grass Identification
OK. Then remember this: "When you hear hooves, think horses, not zebras". Especially without a Spring Pre-M, it's not unusual at all to get Crabgrass. If it's limited, you can fight it with anything containing Quinclorac. With 1-2 acres, that won't really be feasible if it's widespread.
The Weed-B-Gon Plus Crabgrass Control product is available at even HD and Lowes. Since you have significant square footage, make sure to get the concentrate and not the ready-to-use product. And make sure to get a Pre-M down on that lawn next Spring when the Forsythia blooms!

Re: Invasive Grass Identification
Thanks for the confirmation. The lime green color and how it looks in 4" grass compared to alone along the driveway, always had me wondering if it was something else besides crabgrass. And thanks for the advice...it is widespread...I think that I am going to wait until the forsythia bloom to wage the fight.

Re: Invasive Grass Identification
Crabgrass loves heat, and you'll often see it at its biggest/baddest near hotpots like driveways and walkways. You're probably smart for leaving it at alone at this stage of the game on a large-plot -- concentrate on getting the soil prepped for a better day with no crabgrass. Study up on Pre-M's on the site and decide whether you also need a Pre-M treatment for Poa Annua in early September...
