O.K., I just posted a very long reply that did not show up, so I give up.

Drew, when I am not signed in, I see a "Related stories" section below this Comments section (perhaps others see them even when signed in). Indeed they are related. Give a look.

Whatever the weeds are, they are green, your lawn looks great, I wouldn't bother trying to control them. Not worth it.

My lawn is green but mostly weeds and ground cover. We love it!

Here's my 2 cents worth: if you don't live in a deed restricted community with the Nazi lawn police looking over your shoulder, don't worry about it. People used to rave about our lawn in our previous neighborhood and we use to laugh behind their backs because it was full of weeds, we just kept it fertilized, watered and mowed and it was beautiful. We live in a rural area now surrounded by woods so no-one here cares what your lawn looks like or if you even have one. They are farmers and ranchers who couldn't care less about lawns, landscaping, etc. They are too busy trying to feed their livestock or tend their farms. But there is a grass that grows here in the outlying areas of our property that to me, would be the optimum turf to develop for lawns. I don't know what it is, and I need to take a sample to the extension office to identify it. But it is low to the ground, would never need to be mowed, needs no fertilizer, no watering, no chemicals - what could be better for the environment than that? It's not thick and lush like St. Augustine but who knows what it would look like if it was pampered even half as much? I just think we spend too much money, energy and resources on what we think is needed for lawns. Back in the old days, the only people who had lush lawns were the uber-wealthy who had servants to manicure and tend the lawns. Even then they would have flocks of sheep to keep the grass down.

I am also anti-lawn. My front is planted with flowers and ground covers and those areas not planted have beach stones to keep weeds down. My back has a "lawn" for the dog. The "lawn" is fake grass, looks perfect and is no maintenance.

Truly, your lawn looks incredible. I just mow the lawn when too many weeds get tall, which is good enough for me. I did see some dollar weed (the round - leafed plant) , which likes a moist soil. Cut down on the watering a bit and it may disappear.

Rita, here-and-there in the yards occasionally arise individual grass clumps that fit your general description. I would like to see a closeup photo of yours.

Looks like St. Augustine to me. i agree with most of the comments above. Most of my lawn has been converted to a perennial flower garden. However, I do maintain a segment that is part of my front yard and is most visible to HOA as St. Augustine. My solution is simple. I treat it with Scott's Bonus S. It kills almost all the weeds and fertilizes the grass. I use the Bonus S two or three times a year. Works like a charm.

Sure it's great if you don't mind using pesticides on your lawn and harming the environment. The main ingredient is atrazine.Atrazine may protect crops and lawns from certain types of weeds, but it is a real problem for other species. ... In addition, atrazine has been linked to reproductive defects in fish and prostate and breast cancer in laboratory rodents

EPA has classified atrazine as a possible human carcinogen because it has caused cancer in rats receiving high doses over the course of their lifetimes

The EPA's review has been criticized, and the safety of atrazine remains controversial. Its use was banned in the European Union in 2004, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could not show that this could be prevented nor that these levels were safe.

If you are in an area where rainwater will drain into local waterways, it's a good idea to avoid products that can harm wildlife and the environment, and contribute to red tide.
