I think this is the same weed that I posted in this thread awhile back but took some recent pics to confirm what it is.

I did a full renovation on 9/16. Sowed tttf 9/13 and have mowed 10 times since and I'm in 6B. Should I apply herbicide now or wait until spring and what should I use.

These pics are in my back yard in Northeast PA. What's necessary to kill it and get grass going next spring? Thanks.

Tier 1 - I just want something green. Perennial "weeds" that stay green year round are welcome.

The dead grass is probably crabgrass. It is an annual and dies as soon as temps go down into the 30's. However, it is a prolific seeder. You can put down a pre-emergent weed control in the spring when the neighborhood forsythias bloom. Or you can wait until next August or Sept., dump some compost on the areas and seed new grass.

Crabgrass needs heat and sun to germinate. Mow as high as you can during the warm summer months as tall, thick grass will shade the ground and lessen germination of crabgrass.

You could also try that in spring, but in general, fall planting has a better chance of success as it has three seasons before it faces the toughest time of all - summer heat.

I didn't think it was crabgrass cause the rest of the CG died off and regrew as "regular" grass. But this section has always been a mess. Thanks for the tip. I'll try the pre-e. Thanks again

What does everyone thing about this, Think it has stolons, easy to pull out..But I am positive this is not Poa T or A. Also how do I destroy this...I don't want to kill it nicely....It is spreading quite fastly through my renovation...Renovation is KBG(80%) & PRG(20%). Some lingering TTTF that was doing so nicely that i couldn't bare to kill it.

With the thickness and roughness of the blades, I would lean towards tall fescue? Would need a better, up close picture of the collar to be sure. If it is TF you're going to have to go through an application of glyphosate , maybe two.

It seemed like it had rhizomes, I will have to pull another out of the ground this weekend. If it is tall fescue can I help control it by mowing low like 1.5 to 2 inches?
