Hello, I would appreciate help in identifying and possibly offering a solution to "a problem" with our zoysiagrass in our back yard.
I have attached a few photos of "the problem" that probably started about a month ago and has been spreading (getting worse) every week. My guess is that it's probably due to drought and summer heat on the other hand, it may be a disease and would appreciate your thoughts?
Thank you in advance for your help,
Bob

Welcome and Hello;
This was a grass that I had wanted for quite a while, not only is it drought tolerant but resistant to many blights that can take their toll on all but a few. However I found out that during extended heat and drought conditions, Zoysia will enter into a 'high summers dormancy' state.

My brother in law lives in Amarillo Tx. and even with the high humidity, his gets dinged pretty good, though not to the point as yours. So I'm guessing you live in a drier climate ( it would be helpful and you'd avoid a lot of frustrating questions if you filled out your profile - upper left corner - little person icon ).

I really don't think anything BAD happened to your grass, it's actually one tough sonofabuck to kill, almost as bad as bermuda! I suggest the 'wait and see' approach.

Good Luck

Hi @boblink welcome to the Forum

Unlike JR I have had nothing but bad experience with Zoysis grass. I planted a bunch of it in an established yard that had both Bermuda and Saint Augustine and watered and fertilized the same as the other grass. None of it lived. I tried it two more times with no luck. The Bermuda has now taken over that area and is doing well. Hope someone here can offer you some solution.

Thank you Jose, I was hoping that it wasn't a virus and just extreme heat and lack of rain that we've had this summer in Atlanta.
I'll know for sure next spring if the grass is still greyish or turns green again
