Hello, I have this type of grass/weed growing in my lawn that has spread to mostly the whole thing. It looks like crabgrass but I'm not sure it it is. Any help is appreciated thanks.

No, it is not crabgrass, but does look like some well fed Kentucky 31 tall fescue.

you are talking about the plants with the large blades correct?

Response to RE: weed/grass identification w/ pics

that is correct. Definitely NOT crabgrass.

So it is possibly kentucky 31 tall fescue?

I agree it looks a bit like K-31, but at the same time it doesn't. That color is blue green, which isn't typical of K-31. Perhaps it is just a photographic artifact. Also it looks like it has a prominent central vein, as the blades have a distinct fold to them, which isn't typical of tall fescue. Definitely not crabgrass, which is too bad, that's not so hard to deal with. Here's a grassy weed id key that might help. http://www.ipm.ucdavis.edu/TOOLS/TURF/PESTS/grasskey.html

After looking at the close up pics, I see the folded leaf blades, making it less likely to be tall fescue. I don't think it is a bluegrass either. Perhaps it could be orchardgrass. Do a google search for orchardgrass and see if you can find pictures and information that resemble your weed issue.

It looks similar to orchard grass, definitely grows a lot faster then the rest of the grass. I'm also assuming whether it's orchard grass or k-31 there is no way to kill it without killing the rest of the grass.

Any ideas?

My final answer is Orchardgrass. You probably had some contaminated grass seed. If I am not mistaken, Orchardgrass can only be controlled with Roundup in cool-season turf. But keep checking, I could easily be wrong with my weed identification.

Alright, either way I'll have to kill it with roundup or let it be. Another question, is it possible to overseed a existing lawn with kbg without completely killing the whole lawn and get decent results?

This has to be totally killed or it will start to spread again.
I used round up last fall but I missed a couple of patches. It is back!
If you are going to renovate wait until late summer early fall!
Good luck!
