I have these dead patches in my yard they started a year ago and since then I have treated those spots with bug killer cause that's what I thought might be killing the grass,
I let it set for about a thirty days then I seeded and fertilized it.
In about a week grass started to grow it was looking like I have solved the problem all went well until the next summer and the dead spots came back. What do you people think could be causing this problem.?
