the first two pictures are the cushy grass, one is the seed and the other is it in the yard, the next 5 are what i think might be crabgrass. its all over in the front yard, and patches in the back.

your help is greatly appreciated.

idk i'm an noob when it comes to this

Here's what I would do right now. Follow these steps and you will be surprised how fast you have something that looks fairly nice.

1. Water deeply and infrequently. Deeply means at least an hour in every zone, all at once. Infrequently means monthly during the cool months and no more than weekly during the hottest part of summer. If your grass looks dry before the month/week is up, water longer next time. Deep watering grows deep, drought resistant roots. Infrequent watering allows the top layer of soil to dry completely which kills off many shallow rooted weeds.
   


2. Mulch mow at the highest setting on your mower. Most grasses are the most dense when mowed tall. Bermuda, centipede, and bent grasses are the most dense when mowed at the lowest setting on your mower. Dense grass shades out weeds and uses less water when tall. Dense grass feeds the deep roots you're developing in 1 above.
   


3. Fertilize regularly. I fertilize 4 times per year using organic fertilizer. Which fertilizer you use is much less important than numbers 1 and 2 above.
   

how would you suggest i get it to spread? buy seeds or maybe replant some runners to start in other areas of the yard?

Centipede should spread to cover but here is a source for seed.

I apologize for missing that. It seemed so obvious.

Yes, I need to go back to turf ID class. Sorry for the confusion.

and this

but if i search goosegrass in google image i also get pictures that look the same as the ones i circled. But when they grow they look like the one i'm holding. It has such a distinct blade curve. I'm just trying to figure out if it is a weed or actual grass.

so we have concluded that the first two pictures are actually centipede and the others are probably a crabgrass breed?

and i'm not too familiar but i believe that centipede is a rather common grass down here. So is Bahia and st augustine.

My best guess on the weed in question is goosegrass.

I knew that most warm-season grasses exist throughout Florida, but I didn't think of centipede or bahia being part of that list. I have only thought of Bermuda, SA, Zoysia and Seashore Paspalum as desirable turf in Florida.

so just to be clear picture one and two are centipede, picture 3 and the top circled one in picture 6 is goosegrass. now picture 4, 5, the bottom circle in 6, and 7 are all what grass? is that st augustine? picture 3-7 are all one part of the yard. Most of that corner of the yard can be seen in picture 4, so its the one going crazy.

I would just like to know if it is a grass or a weed that will die out in the winter (which will make me sad because it looks so much better than dirt

whew thats alot :/
