You can lose a whole fall renovation in three dry days.
The aeration and the seed are the easy part. What decides whether you get a thick lawn by spring is what happens in the two weeks after the seed goes down.
New seed needs the top quarter inch of soil damp at all times. That means light watering two to four times a day, not the deep soak you would give an established lawn. A seed that starts to germinate and then dries out is finished. It doesn't pause and pick up later.
Once the seedlings are up you flip it. Less often, longer each time, so the roots chase the water down.
We wrote the whole routine out, including how to work out what your sprinkler actually puts down in fifteen minutes.
One inch a week in deep soakings for an established lawn, the opposite for new seed. Charlotte watering routines for both, and the timing that stops brown patch.
