So, I was looking at some plugs I moved last year via the pro plugger.

Mind you I started with 50/50, but the way this is growing in a bunch tells me it is only one half of the 50.

Is this an accurate statement or is it something else completely?

Are there parallel ridges in the blades?

Yes

Yes. PRG.

Thanks, I guess that makes for interesting times when I plant new 50/50 into what may be mostly prg at this point.

Given the recent discussions with @ware and his links to some studies, as it has been a few years, I am not totally surprised to see the progress over take the kbg.

At that point, I wonder the purpose of 50/50.

Two things that I know of:
1) Climate tolerances of PRG [eg. PRG does the best in cool/wet (PNW)] This will help if you're unsure what species will do best over time. (same reason people plant a Northern Mix, without the fine fescue).
2) Ground cover. Germination of PRG is 3-10 days. KBG is drastically longer/slower.

I'm not seeing anything overtaking anything else in your photos. I'm just seeing bare spots where grass died out. That doesn't mean it was overtaken...on the contrary...there's nothing there! PR does not kill existing KBG...not at all. They're compatible in a mix, but the PR is typically more competitive overall. Not always, though.

You're not going to have issues with a 50/50 mix germinating in bare spots.

Valid point. I was thinking more on the idea that maybe prg is an angle. If the patches not dead it seems to be all prg, so this is why I was inferring the kbg was gone. I guess maybe just don't know what I am expecting to see.
