Half my lawn that is divided by a sidewalk is beautiful green St Augustine with no weeds and grows perfect. Other side is St Augustine as well but doesn’t grow as good or as full. It also has this crap pop up in about a 1/3rd or the lawn. I’ve tried the weed and seed stuff but nothing really seems to work.

Dallis grass

Call gecko green

The fact that you have st. Augustine complicates things in that anything that will kill that will also kill the st augustine. It looks like Dallis grass. I have Bermuda, and I use MSMA...which you can't get anymore.

Yep I used some weed killer last year and almost killed the whole lawn, since i didn’t know St Augustine was considered a weed.

Thanks sir, do they service the Sherman area?

Break out the hoe!

Click bait

Pull it by hand and let the grass fill in.

Get the clusters early and they are easier to pull out.

It is a long process.

I used Weedex and the chemical killed everything. The grass eventually filled in after it died.

If they do I would not pay them. Let me ask some homies what they would do and I will see what they say.

If you don't want to suppress, harm or kill the St Augustine, old fashion pulling up the Dallisgrass with the root is the best way to go.

When the soil is moist it is easy to pull & get all the roots.

MSMA will kill St Augustine when applied at a rate sufficient to kill Dallisgrass.

Pick an area and soak it real well, then pull it.

Spot treat with Roundup.

I don’t know Royal, really I was just joking....

I gave up on my green thumb many years ago, I just use a yard service... for all of it.

MSMA spot it and the St. augustine will come back is what I am hearing. I have the same problem but since it is green I have not killed it yet. I have mainly bermuda though and only a side yard is St. Augustine

concur

Sounds like I got some pulling to do lol. I’ve read that if you cut the bottom of a milk jug off and put it over the top of the weed. Then put the nozzle of roundup in the top of the jug I helps with spot treating. I’ll try that.

Keep mowing and watering, the st Augustine will choke it out.

Hasn’t in 2 years I water everyday and mow once a week.

If your yard isn’t huge - make a wick applicator and paint the dallis grass with glyphosate. Just don’t get it on the st Augustine.

See how it smokes before you kill it all, it might be some good stuff.

Over fertilize It. That is put a cup of granular fertilizer on the center of the crown and pour a cup of water on it every day.
The St. Augustine will fill in the void.
Corn gluten meal and molasses will also work.

For anybody else having this issue, or issues with Dallas grass in general.

You can't kill that Dallas grass until soil temps are above 80 degrees. So, now is the time to poison it. Best thing to do is dig it up. Get a small spade and go in at the edges at a 45, work you way around and pop it out. You'll be surprised how fast you can get them out. Fertilizer and water the hell out of the St Augustine. You e kind of missed the window for it to fill in this year, but it will still grow some.

After a good soaking use an old hunting knife, dig it out like you are using a small spade.
