Might be a fungus. With the crazy heat & humidity we’ve had, fungus is thriving. Plus if you don’t bag and that wet grass sits on top of growing grass… Recipe for fungus. I’m guilty of it and my yard is getting spots similar to the pic. Zone 7b

Kinda just looks like malnourished and heat dormant cool season grass. Make sure you’re watering enough but not every day.

Could be grubs, disease, rocks under the soil… lots of things. Dig and you’ll find out!

Assuming you just went through the same heat wave I did in 7a these areas most likely went dormant. It looks like a lot of it is right next to the pavement, which is due to the pavement heating up more than the surrounding areas.

Fungus or pet urine

People allowing their dogs to pee on your lawn. That is why it is only near curb.

Looks like 2 different things: heat stress from that crazy hot weather we had and pet damage near the curb.

Fungus likely. Hugh dollar spot risks right now like over 50% from greencast warnings I have been getting I have seen it on many neighbors grass walking

I had the same. I think a mix of over-fertilized plus that wet/warm. Found a few grubs, too. So I’m guessing everything, everywhere, all at once.

It’s fungus. If you don’t act now, you are risking the entire lawn. And if you think that more water will help… you will be disappointed.
How do I know… I lost a lot of lawn exactly this way.

1st step, use a soil plug in those areas and see how far down it goes before you hit something hard. Could very well be gravel overspill from when the driveway was installed which is very common. Second step, get on your hands and knees and spread the grass right at the edge of the healthy grass and dead grass and check for chinch bugs and bill bugs. They are very tiny and will scurry away when you spread the grass but will come back if active so wait a minute while looking.

Green five days ago and it went brown this fast? I would suspect fungus.

Looks like dog urine damage to me. I’ve had to fight it with neighbors a ton. Dogs find places to go and consistently go in the same spot. More dogs follow.
Possibly fungus. Wouldn’t hurt to put down some fungicide.
I doubt it’s heat. The picture you’re showing has it in the shade right now and the grass around it is very green.

Same here same zone.

Could possibly be from that shock heat wave when it was 90+ degrees. Happened on a part of my lawn as well.
