Serious question, had to choose between a 4-foot frost depth and a 6-foot for a big cedar job in Minneapolis last month.
Honestly, the ground was still pretty hard and the client wanted to save cash, so I went with the 4-foot posts. Ngl, we had a major lean after that last big freeze and now I'm redoing half the line. What's the absolute minimum depth you all use for a northern winter like that?

Feel your pain, that freeze-thaw cycle up there is no joke. I learned the hard way too, skimping on depth just costs you double later. For anything that needs to stay up in Minneapolis winter, I wouldn't even think about less than five feet now. That extra foot is cheap insurance compared to redoing the whole job.

Oh man, trying to save money on post depth in Minneapolis is like using a screen door on a submarine. You see that four foot hole and think it looks deep enough, then winter laughs and moves your whole fence six inches to the left. That extra two feet of concrete is way cheaper than your back surgery from fixing it later.
