So, you're thinking about a cedar garden bench and keep hearing they're "rot-resistant." But is that marketing hype or solid truth? Let's dig in. The short answer is yes, Western Red Cedar and similar species are genuinely resistant to rot and decay—but with crucial context.
Cedar's secret weapon is its natural oils and tannins. These compounds act as built-in preservatives, making the wood unappetizing to fungi, insects, and moisture that cause rot. Compared to many other common softwoods, it's a champion for outdoor use. However, "resistant" is not the same as "immune." In consistently wet, shaded conditions with poor air circulation, even cedar can eventually succumb.
The heartwood—the dense, inner part of the log—is far more durable than the outer sapwood. A quality bench made from heartwood-rich pieces will last decades. You'll know it's working when you see the wood gracefully silver to a soft grey; this is natural weathering, not decay.
To maximize its legendary rot-resistance, give your bench a little help. Place it in a spot with some airflow, not directly on constantly damp soil. An annual cleaning and a fresh coat of sealant every few years will dramatically extend its life and beauty. Ultimately, a cedar bench is a fantastic, low-maintenance investment. Its natural defenses are real, offering a blend of durability, beauty, and timeless charm that few other woods can match for your garden sanctuary.
