Choosing the right wood for your garden bench is crucial for longevity and aesthetics. The main contenders are pressure-treated pine and cedar, each with distinct pros and cons.
Pressure-treated pine is lumber infused with chemical preservatives under high pressure. This process makes it highly resistant to rot, decay, and insect damage, offering great durability for ground contact. It's the budget-friendly champion, costing significantly less than most durable hardwoods. However, it requires sealing or staining every year or two to maintain its appearance and prevent weathering, warping, or checking. Its look is more utilitarian, often starting with a greenish tint that fades to a silvery gray.
Cedar, on the other hand, is naturally rot- and insect-resistant due to its inherent oils. It offers superior beauty with a rich, warm color and attractive grain that ages gracefully to a silvery gray. It requires less maintenance; a simple cleaning or occasional oiling is often enough. The major trade-off is cost, as cedar is more expensive upfront. Its natural resistance is robust but can be less uniform than the engineered protection of treated pine, especially in very wet conditions.
So, which is better? For maximum durability on a tight budget, especially for benches directly on soil, pressure-treated pine is a practical workhorse. If you prioritize natural beauty, lower maintenance, and a more organic appeal and are willing to invest more, cedar is the elegant choice. Your final decision should balance your budget, desired maintenance level, and the visual role you want your garden bench to play.
