You may have grasses blended in that go dormant during cooler weather, like
zosia...

My lawn is half green and half brown. I can't figure it out.
The blades that are green look great. But there is a 50/50 mixture of
dead brown grass that is still rooted to the ground.
Last year I mistakenly thought this was thatch, so I bought a
dethatcher. But then when I learned how to check thatch by looking at
a cross section of the soil and grass, I found I had no thatch
problem.
Here's what it looked like last year:

The pictures were taken before the drought, so it wasn't a water
problem. You can see what it looks like compared to my neighbor's
yard!
Can anyone help me?
I'm in northwestern Illinois.
As the lawns are waking up, I can already see that it's going to look
the same as it did last year.
I plug-aerated in the Fall, and put down winterizer.
I've put down my Scotts pre-emergent/fertilizer already.
I'm willing to do the work, but I'm at a loss as to what the problem
is!
