I've got this grass growing in a yard I treat, but I guess I'm not sure what it is now. Always been mowed at 2.5 and is seeding out each time. Any suggestions on what it is exactly and should anything be done about it?

Ryegrass is seeding at this time of year. May just be that.

Had a guy call me the other day all frantic about weeds in his yard. I got there and it was the same thing your seeing, it's seed head (fescue) and will die out in a few weeks with the hot weather.

it is natural for all living things to reproduce. Grass plants are no different. What are you are observing is the grass plant going to seed. For most northern grass types anyway this occurs in mid to late May. The plant sends up a stalk from which the seedhead imminates. This process puts a fair amount of stress on the grass since it expends alot of energy to do this natural fuction. After mowing the seedhead is cut off leaving this "stalk" - this is referred to as stemming. The slalk will die off leaving a yellowish appearance to turf.

Sorry about the poor quality photo! This lawn is supposed to be all bluegrass, as are the rest in the neighborhood. This lawn hadn't been well taken care of in past years and a new sprinkler system was put in last fall. Only reason I'm asking is I thought it was bluegrass however none of the other neighbors yards are seeding out like this and they're growing much faster between mowings, some are 3.5-4 by the time they're cut every week. Will this "come around" with continued fertilizer and proper watering? Is the seeding out at low heights due to poor quality soil and/or plant health? Top soil is not too bad, but about 1.5-2 inches down is heavy clay soil. Recommendations???

Reccomendation is to just wait it out. It's a naturally occurring function that won't last all that long. Kinda interesting though how many different opinions about what kind of grass it is. You should really look up the physical characteristics of the grasses in your area and try to ID it yourself so you know in the future.

I believe blue grass is the only one that has a single vertical crease or stripe going down the center of the leaf and the rest of the blade is smooth, this will tell you at least if this is Bluegrass or not.

We've got alot of that in some of our neighborhoods here in WI. We haven't taken it to a horticulture expert yet, but we're convinced that it's a "rough bluegrass". We cut all the way down to 2" and still cant get it below the seed head in some areas.
We don't like it due to the fact that it has a very hard and wirey single stalk. Most of the manicured lawns up here really don't want it. Interesting to note that to a "T" they all say that they overseed with a sunny grass mixture they buy at the local big box retail outlet. Gives me a very strong case for overseeding with professional quality grass seed.
I would love to get a 100% ID on this grass.

I would recommend you do a soil sampling and determine exactly what kind of fertilizer to use.
Your results will be better if you fertilize for what is needed.

You definately got me into "research" mode over this one. I've narrowed it down to the following:
Poa Trivialis - Rough Bluegrass
Poa Annua - Annual Bluegrass

Thanks for bringing this up. It's solved a mystery for me this spring!

Looks to me like it is Orchard Grass, or that's what everyone around here calls it. I'm not sure what the scientific name is. The only reason I recognize this is because we cut some hay and it always shows up in our alfalfa fields. You might need to add lime to your soil to cure this one!

To add to this point, Rough Bluegrass tends to grow in wet or shady areas. Where Annual Bluegrass is commonly found in sunny locations. This might help you a bit. Also, Annual Bluegrass seedheads have a distinguishing white color.

However the photo you supplied lacks enough detail to make a good guess.

ckelly, as you see, you cannot get an accuate ID of a grass plant from a picture, LOL. Even a very good picture would be just eliciting guesses.

Grasses and most others things in nature are positively identified by using identification keys. The item in question is keyed out, using definite physical characteristics (often needing simple magnification) to do a step by step elimination process until you isolate your species in question.

To get a turfgrass ID key, go to <a href="http://www.lawnsite.com/showthread.php?postid=654358#post654358">THIS POST</a> of a few weeks ago. key link is about 3/4 down in posting.
