It is extremely invasive and spreads throughout the whole area sending out roots underground. Scotts is my lawn company and they told me it is very difficult to control and is spread from yard to yard by lawn companies cutting lawn after lawn. I wait until mine get to a manageable size and then hand pull them.

The weed in the OP is not nut grass.

If I'm not mistaken it's called St Augustine's Bent Grass which is not a weed at all unless you have another type of grass lawn.

Many lawns in the Villages and in much of Florida are planted with St Augustine's. It is not the type of grass we are used to in the north. Up there we called is crabgrass, but I think that even crabgrass is different.

I believe that there is a weed and feed fertilizer that will help to reduce and/or eliminate St Augustines. You could just check with Lowe's or Home Depot. I'd bring a piece of the grass with you and show it to someone over there.
