A. Cedar lumber is naturally weather, rot, and insect resistant. Natural and treated whitewoods (pine, spruce, and fir) are not likely to weather as well as cedar. As noted on the American Fence Association Product Guide: “Cedar is not only aesthetically appealing but a practical choice, as it’s durable and can be reasonably priced. It’s a popular choice in areas that are fire-prone as it meets and exceeds safety classifications in the majority of areas across the United States. While many people choose to enjoy the beauty from a natural, untreated cedar fence, others choose to treat their cedar fences. As it is porous, it naturally takes to stains and paints, making initial painting and further maintenance a breeze.”
