Are you watering yet, and if so, how frequently and how long? Or have you gotten rain after rain after rain? Because it does look like a disease process.

Not watering yet. It rains basically all April here, so the ground hasn't dried out much yet. It's supposed to rain 3 days this week.

Is that a new concrete pad?

Nope, it has been there for probably 15 - 20 years.

Well, there goes my easy answer. It's a bit early for disease in that climate, but check the blades of the still living turf at the boundary between green and dead to see if you spot any lesions. Lawn mowers or foot traffic can transfer disease. If not, it may just be dry spots due to hydrophobicity or a soil structure problem. A soil test would be called for.

Was there any sign of snow mold?

Nope. I thought maybe too, but no fuzzy stuff on top of any of the spots. Just dry crunchy grass (soil is not dry.)

Are you thinking it's not "Spring Dead Spot?" It's not super circular but I don't really know much about that disease. I almost just want to spray the whole lawn with fungicide as a preventative.

By the looks, I assumed you have a cool season turf. Are you saying you have Bermuda or Zoysia? I don't think that disease effects cool season grasses.

It's definitely not Zoysia, I know that much. We had Zoysia at my last house, and it generally doesn't green up for a few more months. Last year, these spots were green by now (I think.)

And according to my research, Spring Dead Spot only affects Bermuda grass. But I have no idea what kind of grass I have.

Thanks for trying! :) I'm just desperate to have a nice lawn after last years fiasco with fungus and reseeding part of my yard. I'm hoping to nip this before it gets worse.

I am not a professional but a homeowner like yourself. This looks exactly like something that happened to my lawn in Idaho. The only fix I found was to dig up and rake out the dead area as clean as possible then reseed with new top soil. In a couple weeks it was looking good. I went with a sunny seed so it would still look nice when temps hit 100. In SW Idaho (Boise) it goes from freezing to very hot in a few months then back to freezing again.

That's either Bermuda grass or zoysia. You don't have a fungus. That grass will green up in the next month.

Are you fairly confident in that Joneboy? Not to doubt, just want to get rid of this ASAP if it is something else.

The weird "patches" of white, as opposed to all over were what made me question the grass. It just seems odd for it to be so dead in places. (There's also a large super dead spot by another fence that connects to the neighbors, but it looks different than the rest.)

S McCabe, yeah pretty sure. From your description of the recent weather pattern the only fungus that might be active would be dollar spot, and I don't see any dollar spot activity there. The grass in question does not look dead to me. Dead grass collapses and mats down. That grass just looks dormant to me, which make me think it is a warm season grass. The first thing to do is figure out what kind of grass you have. The easiest way to check is pull a rake or your hand through the tan grass and you should find stolons, both zoysia and bermuda grass have stolons. Once we identify the grass we can move forward from there.

Joneboy, I looked and it does have stolons. It seems to be greening up a little so far. Thanks for your help. I was just paranoid I was going to have last year's fiasco on my hands again.
