Could you pull some of it with the roots and ground level growth. Zoom in close. and lay the grass on a white sheet of paper. It's almost impossible to see from these photos. When were these photo made?

Ant,

It is tall fescue, I had the same situation with in the last two weeks. Looks like hell. Check the link below, it is perfect for this weed id.

"Do-It-Yourselfer: Is it Crabgrass or Tall Fescue?

We have received a number of calls this year about trying to control the crabgrass running rampant in lawns. It's a much more coarse bladed and lighter green than the rest of the grass, so it must be crabgrass? It's not crabgrass and is more likely tall fescue. Though crabgrass and tall fescue may look similar in summer, they are easy to distinguish now. Crabgrass is a summer annual and will only start to germinate in mid-April or later in Indiana , so it is not visible in lawns yet. Conversely, tall fescue is a perennial and is obvious in lawns now because of it's coarse texture, usually lighter green color, earlier green-up than many other species, and accelerated spring growth. Digging it out or spraying with glyphosate or gluphosinate are the only ways to control tall fescue. On the other hand, applying a preemergence herbicide by early to mid-April can prevent crabgrass.

Tall Fescue doesn't usually sport narrow leaves that clasp a stem so high as seen in the upper left corner of the bottom image.

Need to see auricles, ligule sheath, etc. Does the camera have a "macro" setting?

Termor,

I could be wrong in my ID. However I did bring the plant back to the office and break out my ID guides and hand lens.

The photos Ant posted and the timing match my situation, additionally he is located fairly close.

I'm still curious what everyone else ID's this as.

you must have different tall fescue in your area. Tall fescue is grown here for grass seed, although it is considered a noxious weed in turf. There is an ornamental tall fescue know as dwarf tall fescue. Again, that does not look like tall fescue as the blades look thin.

most Tall fescue doesnt grow in clumps like that. KY 31 does. you can fix your problem with a product called CORSAIR made by Riverdale. Active ingredient is Chorsulfuron. It also traets for rye grass. try it and you will be well pleased. nathan

The weeds besides the clump are chickweed. I have had the same problem with the clumps here in NC and its been here well over a month before crabgrass would show up.

I don't know what it is and my licensed sprayer says that he is seeing it everywhere and its not crabgrass????:confused:

Two things. First, this isn't tall fescue. Second, i don't know how old this writing is of Zac Reicher, but it is not 100% correct, either. As both Tremor and Nathan stated, it does not match the description, and as Nathan pointed out (excellent point), chlorsulphuron works as a selective to control it. Open another window, and go to this link. look at the grass and seedheads, and compare them to the pic on here that has the seedheads. Tell me what you guys think. i DO wish I could get an up close view of the plant and leafs, though. http://www.agry.purdue.edu/ext/forages/publications/grasses/orchardgrass.htm

I still believe it is tall fescue, however I am open to being proven wrong.

Thats what I am here for, to always continue to learn.

Put me down for tall fescue too.

The broadleaf weeds next to it might be clover? Chickweed is less common in sunny areas, plus it is not very tall. Pictures are not quite clear enough, but whatever the broadleaf is, I'm sure it's easy to kill.

This looks more like Annual Bluegrass Poa annua, control with pre-m, dimension really any of the pre-emergent herbicides. Or spray it with lifeguard or stonewall. This doesn't look like tall fescue to me. A good clear close up picture will give you the tell tale difference between the two.

I am leaning toward rough stalk bluegrass.poa triviallis( clump,light color etc.) Does it fade out during hot weather and bounce back in early fall?
