When do you shut off your sprinkler system?

Depends where your backflow valve is, and how well it is insulated against the cold, it is the part that is most susceptible to freezing/damage. None of the zones should have water in them if the system was installed correctly, only water would be up to the master valve.

I turn ours off when we have hard freezes, back on when it thaws. I water year around based on the amount of rain/precipitation we have had, and how dry the soil is.

My watering is year round from my areobic septic system.

My watering is year round from my areobic septic system.

I added 5 sprinkler heads to my aerobic system. Those line are below the freeze line. When I tied into the existing lines, they were a minimum of 24" deep. And that system should not be turned off!

A properly designed irrigation system should have gravity low-point drains. As mentioned above, if the ambient temperature is really low the system could freeze at the nozzle when running but it would have to be really cold.

If you are in an area that requires an above ground back flow preventer, you will need to winterize it but it's easy. If you have an outlet nearby, just wrap everything in heat tape and cover it in foam. If not, just shut off the main valves and open the release valves to winterize. During warm spells you can close the release valves and main valves and continue to water as desired.

I never water in the winter and my crepe's survive just fine.

The yard guys just painted mine green, so I'm good to go this winter.
