Wood is strong, stiff per unit weight, easy to work with, attractive, and economical. And it rots. A few special types of wood, such as teak, are highly resistant to rot, but these woods are generally heavy and almost always expensive. Pressure treated lumber is an option, but it’s ugly, warps, does not take coatings well, and is not always very rot resistant. Western red cedar, on the other hand, has long been used in canoes, and cedar fence posts have a deserved reputation for durability. We started our rot resistance testing eight years ago in 2015, and we finally cleaned out our accelerated rot test box in July 2023. Results ranged from abysmal (untreated samples of fir have nearly disappeared) to astounding (our teak samples are still just like new). Let’s see what we learned.
