Protecting your wooden planter boxes from moisture damage is crucial for their longevity. The right lining creates a barrier between wet soil and wood, preventing rot that can destroy planters within just a few seasons. For optimal protection, start with a plastic liner - either pond liner or heavy-duty plastic sheeting - punctured with drainage holes that align with holes in the wooden box. This creates an effective moisture barrier while allowing excess water to escape. Alternatively, landscape fabric provides excellent drainage while keeping soil contained, though it's less waterproof than plastic. For those seeking eco-friendly options, consider using a metal insert or naturally rot-resistant wood like cedar as an inner layer. Always ensure proper drainage by drilling 1/2-inch holes every 6-8 inches along the bottom and sides near the base. Elevate your planters slightly using feet or bricks to enhance airflow and drainage. The combination of these methods can extend your wooden planter's life by 5-10 years, keeping your urban garden thriving season after season.
