Can anyone identify the cause of this yellowing?


Started noticing this about a week ago. I initially thought it was due to the excessive heat we've had for about a week and a half along with no rain. I watered it but saw no improvement.

Today as I'm driving down the street I notice that many homes have the same issue, with some being completely yellow in big areas and others having lots of smaller splotches of yellow like mine.

I no longer think this has anything to do with the heat or lack or rain. I'm hoping that someone knows what's causing this and how to treat it. Thanks

I'm sure the expert gardeners will be along, meanwhile,

Grubs are eating the roots of the grass. Grubs are Japanese beetle larve.

And the birds will destroy the lawn if the moles don't get there first.

Any roving dogs in the neighborhood?

Their basic toilet manners will do that.

If grubs you should be able to roll back the turf. Since they eat the roots.

Pic not good enough to tell type of grass.

My guess is still the heat. And it is a cool season grass.
Yes grass needs water at least once a week minimum. But water is still not air conditioning.
Areas that have some shade should look a little better. Parts in full sun worse.

A cool season grass first defense is for the leaves to turn brown and go dormant to protect the roots.

@Dave Sal , I concur with @RRH .

When we had heat waves in Ohio, the grass would do that. Also, was your grass recently planted? I recall an earlier thread where you had planted or were contemplating planting grass seed.

Good memory, but no, this is the grass in front of the house. The backyard is where I laid sod a couple years ago.



Thanks for all the replies everyone. I'm thinking it's most likely "Summer Patch" as mentioned in Nik333's link, or grubs. I'm going to check for grubs tomorrow. Now that the heatwave is over maybe things will start to green up once again.

Inspect really closely. Give a gentle tug on the browned grass. If it's rooted in reasonably tightly, there's a good chance it might recover. If the blades appear discolored or "melted" in places, you might have a case of fungus (summer patch is so misleading).

I'm pretty sure it's NOT doggie damage at least.

If you give a shot of extra water and some liquid fertilizer like Miracle grow from one of those sprayers, it should send out new blades. If there's signs of fungus treat with fungicide.

How's the backyard doing? I trust well from our expert advice?

Update:
I went out this afternoon and yanked on a bunch of different yellowed areas of grass and the turf is not coming up. It all seems tight to the ground, so I'm thinking it is a fungus. Thanks again for the replies.

Re: Can anyone identify the cause of this yellowing?


These have good info. There has been conflicting advice on fertilizer, in other articles, but perhaps once it has a fungicide, it can have fertilizer. Think of it like Athletes Foot, although of course it isn't, many of the rules are the same.

Keep a close eye and let us know if it grows back.

I tried to find a good picture of long-post-mortem doggie damage, and didn't find the best picture, which shows a dead area, with this halo of extra-lush grass, gradually tapering off to normal as you get away from the spot. Couldn't find one; the pics I did find look like fungus.
