Grass getting brown patches. Applying good soil and water…hope this will help!!

[Hopeful1]

We have dry brown areas in our beautiful St. Augustine grass.

I bought 4 bags of good soil at Home Depot yesterday.
Had my son spread it out and water it. I will need to get 4 or 5 more bags
to cover the area. I need to get a new sprinkler also.
Is anyone having a problem with brown patches?

I have a patch near the back porch that wouldn't keep grass no matter what I do. Now there's the end of some kind of cement slab pushing out of the ground. Don't want to know what that is. I swear if bones start coming up I am selling and moving.

Maybe it’s an old sidewalk. At our previous house we found a very long sidewalk under 2 inches of dirt and grass.

Yeah that's probably what it is.

I'm not familiar with St. Augustine myself as I don't have that variety in my lawn but I did come across an article about why St Augustine grass can turn yellow. Hope it helps you.

Not sure if this variety of grass reacts to heat and sun like other grasses by going dormant during times of high stress then comes back when conditions are more favorable? I know Kentucky Bluegrass & ryegrass do this most summers here in the north anyway.

Most grass, not all, will go dormant during heat waves with lack of rain. It will probably start coming back at the end of this autumn. If not, for certain, next spring. The top soil will help once it starts growing in again.

Thank you!
That‘s what I was thinking.
