Sorry about the language. I was frustrated. Lol. But, I live on the Virginia/North Carolina line.

And I was under the impression that it was centipede. But, it could be St. Augustine. I've definitely been wrong before though.

I'll try not to get frustrated or discouraged. Its a process.

dchall, he tried to figure out which grass he had in this post:

thoughts?

Im surprised that you remembered that @TS Garp

Actually it's your complicated state tax situation I remembered, lol.

Lolol. Well I always say that because people automatically put me in a different climate zone when I say virginia.

It's definitely crabgrass. :(

I'm trying to think if there is anything that I can do this late in the season to get rid of it.

But, I'm drawing a blank. It's probably too late for Celsius. And I'm sure it'll kill the little bit of centipedegrass that I actually have.

May be too much of it to manually remove.

Just cut it?

Okay. That earlier post, which I missed, shows St Augustine. Go to the earlier one and enlarge the picture showing the runner escaping into the dead zone. In the lower left you can see the classic boat tail shape of the St Augustine blades. Centipede has pointed blades.

If you planted centipede into St Augustine, no real problem. The St Aug will take over completely. I can't watch the video at this time (at work), but I suspect you have a watering problem...or a water accumulation problem. Is that dead area a low spot?

Watering: Deep and infrequent is the mantra for watering. This is for all turf grass all over the place. Deep means 1 inch all at one time. Put some cat food or tuna cans around the yard, and time how long it takes your sprinkler(s) to fill all the cans. Memorize that time. That will be the time you water from now on. My hose, sprinkler and water pressure takes 8 full hours to fill the cans. Your time will likely be less. I like gentle watering. As for watering frequency, that depends on the daytime air temperature. With temps in the 90s, deep water once per week. With temps in the 80s, deep water once every 2 weeks. With temps in the 70s, deep water once every 3 weeks. With temps below 70, deep water once a month. Note that you have to keep up with quickly changing temps in the spring and fall. This deep and infrequent schedule works in Phoenix and in Vermont, so it should work for you. The reason for deep and infrequent is to grow deeper, more drought resistant roots and to allow the soil to dry completely at the surface for several days before watering again. If it rains, reset your calendar to account for the rainfall.

I hate to say it, but I'd nuke that whole area & lay down St. Augustine sod. One & done. Seed sucks

The seed heads are different in St augustine. It's centipede

Can you get centipede sod?

I may be able to drive an hr or so to find some. Wouldn't spring be the best time to do that? Or no?

Kind of wanted the challenge of growing it from seed. May be a fruitless effort though.

I get it, we've all been there. Seed seems so easy at first, but this forum is full of frustration aimed at those evil little seeds. My experience was the same my first year with Bermuda grass. Turns out warm weather grasses are notoriously difficult to establish from seed. Like I said earlier, seed sucks
