Weird brown spots in St. Augustine
Posted on 7/31/22 at 7:25 pm
Posted on 7/31/22 at 7:25 pm
Yesterday after I cut my grass three small brown rectangular spots showed. I haven’t had any browning all summer and I have been making sure to put 1-2 inches of water on it weekly, wether by Mother Nature or by Father Sprinklers. I did apply some liquid fertilizer (20-0-0) in the middle of June but I made sure to keep it watered so it wouldn’t burn up.
I’m unsure what is causing this and how to treat it any help is greatly appreciated!
Hopefully these pictures load up

Fungal disease. Spread some Scott’s Disease Ex.

Last month my beautiful front lawn did the same. Brown patches appeared out of nowhere. I didn't do anything, but fortunately it only lasted one one mowing cycle and new grass overtook it. By my last cut two weeks ago, any brown was barely noticeable, and today it's back to normal.

Doubt it’s fungus. Grey leaf doesn’t look like that and it’s too early for large patch. YouTube how to check for chinch bugs. Could possibly be the mower scalping a little bit too much off the top.

Well I did get a new zero turn and cut it this weekend, but I set the height on 3”. I’m actually away at work but my wife said they have gotten slightly bigger.
I’ll look into the chinch bugs as well. Do you think it’s to late to do some aerating?
I’ve put a lot of sweat into this yard and I owe it to y’all. I’ve been following all of the posts on this board for sometime.

Mine got sod webworms this time last year….do you see any little white moths around?

Never too late to aerate. Post some close up pics of a damaged leaf.

According to my wife the spots are starting to get bigger. I’ll be home home tomorrow and I’ll post some pictures of the leaves and I’ll check for any moths

[/url] [/img] I just got back from a work trip and I believe chinch bugs are the culprit. There are a few new spots in the front and now about 5-7 in the back yard. I’m going to tractor supply and Home Depot to find a good pesticide, so I can wage war rather quickly.
I did do some reading and they recommend dethatching the lawn as part of the treatment. Several blogs I have read frown upon detracting St. Augustine because it doesn’t have rhizomes. However all of those blogs recommended aerating instead, in the late spring and early summer. I was going to wait until next year to aerate, but with Ronk’s approval, I think will go ahead.
What’s the boards opinion on dethatching St. Augustine vs Aerating?

Browning from the tip down is strange. Are you under any drought conditions where you are? If you grab a hand full of grass and tug does it come up easy?
Don't dethatch St Aug. I've done it a few times but mostly because people let their grass get 8 inches tall and then cut it down to 3 inches. Aeration is where it's at.

We are technically in a drought but I have been insuring between the occasional afternoon storm and my own watering to put 1-2 inches of water on it every week.
As far as it coming up easy, when grabbing a handful, no it’s pretty tough.
I just sprayed some Seven Insect Killer and I’m watering it in now. Hopefully that’ll help or at least I killed any other potential bugs.

Had those frickers for 3 years in a row. Finally gone. They are a pain to get rid of if that's what it is.

I feel ronk is right on spot, as usual. He diagnosed my brown areas (Centipede) a few weeks ago. A few rains, God's fertilizer, and looks good again.
ronk, is Centipede worth aerating/dethatching?

Aerating yes. I suggest doing it once a year.

Liquid?

No such thing as liquid aeration. That’s a scam. The only good aeration is a core aeration
