My St Aug looks like crap after Scott’s weed & feed

looks like some of that green was weeds and it did what it was supposed to do

Looks like cinch bugs, get white piece of paper and scrap some of the brown gras and claw down to dirt, put some of it on white paper you will,see,if it’s chinch bugs.

Not cinchbugs, wrong time of the year - they occur when it’s hot and dry, so you can rule that out. It looks like areas where you may have stopped the spreader without closing the shute on the spreader and overdosed it.

Couple pieces of sod or just wait

It killed the weeds and brown areas remain where weeds were. It did it's job.

Close-up it looks like dead grass, but if it was Bermudagrass patches in active growth within St Aug lawn and an atrazine based weed & feed was used, it would have killed the Bermudagrass.

OP - when did you apply the weed & feed?

Applied it 2/29. Obviously still looks like this.

Is that a St Augustine grass lawn where the grass is not dead?

Going forward - avoid weed & feeds. Feb 29 is to early to apply fertilizer even in New Orleans. Just kill the weeds as an activity separate from fertilizing your lawn.

Advice going forward. Any product applications are meant to be stopped after each pass. A spreader has a drive wheel (a wheel that turns propeller) the propeller will only throw product if the drive wheel is moving. If you try to make turns with the spreader open and the drive wheel isn’t turning product will simply drop out of the spreader and burn the grass.

I'd just wait for it to fill in. Keep it well watered once hot weather arrives.

My neighbor burned every blade of St. Aug in his back yard one year. 100% of it was brown. Must not have killed the roots though. He kept it watered and it came back looking good after several weeks.

Water and wait. There's not fast fix for this without resodding. Lesson learned
