I wasn't sure where to post this on Lawnsite since to some this stuff is grass and to some it's a weed. By common names it is known as Annual Bluegrass or Annual Meadow Grass for those not familiar with the Poa Annua term. Anyways, in my case this stuff is a weed. The reason being is this is a short variation of it that seems to be exhibiting seed head early in the year at a pretty short height. And boy oh boy is it showing off seedhead!!! It is so much to the point that it just looks like a big patch of white in contrast to the beautiful green tall fescue it is in. I don't mow close enough to remove the seedhead at each cutting. So I hate this **** and I want it gone now!!!!
