However, avoid using treatments that contain harmful chemicals that may leach into the soil.
If you choose to stain or paint, be mindful that it may change the natural appearance of the wood. Many gardeners prefer to maintain the natural look of cedar since it blends well with garden environments. If the natural finish is desired, regular oil treatments can be applied to maintain the wood’s beauty while providing maintenance of its performance.
