Do you mow on a set schedule or just when the lawn starts looking rough?

I’m in California, and I’ve been trying to get more consistent with lawn care, but I still end up mowing based mostly on how the grass looks rather than following a fixed schedule.

During faster growing weeks that can mean mowing every 4–5 days, while other times I leave it for over a week. I’m curious whether most people here stick to a regular schedule or adjust based on growth, weather, and season.

Has following a schedule made any noticeable difference to the health or appearance of your lawn?
