Can cedar outdoor tree boxes be left untreated in shaded areas?

Cedar outdoor tree boxes are a popular choice for gardeners due to their natural durability and resistance to rot. However, leaving them untreated in shaded areas can pose challenges. While cedar has inherent weather-resistant properties, prolonged exposure to moisture and lack of sunlight in shaded spots may accelerate decay. To extend their lifespan, applying a protective sealant is recommended, even in low-light conditions. Regular maintenance, such as cleaning and inspecting for mold, will also help preserve the wood. For those preferring a natural look, untreated cedar can still last several years but may require more frequent replacement. Balancing aesthetics and practicality is key when deciding whether to treat cedar tree boxes in shaded environments.
