Yes to annual bluegrass. He over seeds will tall fescue every year. Not top dress with soil...need something on label that's safe for the fescuse but kill the bluegrass.... should we just use gly. On whole yard and reseed? Hate to do that cause its a beautiful lawn. Just few problem areas where the bluegrass keeps coming back each year.... is it from bad seed?

Do this right my friend, if they have a beautiful lawn then make sure they follow the pros. Here is a link from OSU's team and I think terrific advice.

It is not from bad seed. Crabgrass seeds are tiny and blow very far in the wind, travel on animals and birds. One plant can produce thousands of seeds, and the plants are typically everywhere. The best defense here is good offense (prevention).

The only thing you or they might be doing wrong is letting the areas grow long enough that seed heads form on them. Then somebody mows them...the seeds from the clippings spread and drop. Crabgrass seeds can sit dormant for years, and thus it is a problem that can go on and on. Once prevention is begun however, the problem will pretty much be gone in 1 or 2 seasons.

I read the article and its very informative but I've yet to still read or find what chemical to use.... I can skip overseeding this fall because the lawn is so lush and thick if I have to just cause of the timing of the pre... this annual bluegrass is in the lawn year round... not just winter.... I hadn't found anything that's safe on the fescue but will knock out the annual bluegrass....

I do not have crabgrass problems that's simple enough to fix.... the problem is bluegrass in tall fescue lawn.... the bluegrass is different color (shade) of green and is noticeable

Doesn't the annual poa, die in the winter and have to come back from seed in the Spring,,, just like CG???
If so,,, then treat it like CG with pre-m and quit over watering it to encourage seed growth while stunting real grass maturity...
