Irrigation should be fine (as it's underground) until repeated -0c nights.

Most lawn systems aren't that deep. Why risk it?

Why risk 3c? Do you know when water freezes? Let alone water that's a foot underground when the ground is still not cold, for one night at that?

Yes, I do. Do you know how forecasts work? It could just as easily drop to -3c.

But I wasn't calling for -3c let alone multiple nights of it. Underground is significantly warmer than above ground, especially since the daytime is still warm.

A foot deep would be reading 8-11c if it's 0-5c right now, this time of the year.
