Yes, you can absolutely use a sealant on wooden urban planter boxes to make them last longer. Applying a sealant is one of the most effective ways to protect the wood from moisture, rot, and weather damage. For the best results, use a sealant specifically designed for outdoor wood, such as a penetrating oil-based sealer or a waterproofing wood stain. It's crucial to apply the sealant to all surfaces, especially the interior where soil and water make constant contact. Ensure the wood is completely clean and dry before application, and reapply the sealant every one to two years for ongoing protection. This simple maintenance step will significantly extend the life and beauty of your wooden planters.
