Just read that cedar posts can last 30 years in the ground without treatment
I was looking through an old trade magazine from 2005 and they had a study on post rot. It said untreated cedar, if the heartwood is used, can go three decades before failing. Anyone have real-world experience that matches up with that?

Depends on what you mean by failing. My dad's old pasture fence had cedar posts that were still standing after like 25 years, but they were pretty wobbly and soft at the ground line. They hadn't fully snapped but you couldn't tighten a wire on them. So maybe they count as not failed, but they were definitely done for practical use. Did that study say what they considered a failure, like total collapse or just not holding load? That seems like a big detail.

Honestly, that study sounds like best case scenario. Ngl, most real world stuff starts getting sketchy way before 30 years.
