Protecting your wooden planter boxes from rot is key to their longevity. The right liner creates a crucial barrier between the moist soil and the wood. For most situations, a breathable, permeable liner is the best choice. Landscape fabric or geotextile cloth is highly recommended. It allows excess water to drain out, preventing waterlogged soil that accelerates rot, while still protecting the wood from constant dampness. Ensure you line the sides and corners smoothly, but never line the very bottom. Instead, drill several drainage holes in the planter's base and cover them with small stones or pebbles before adding your fabric and soil. This creates a drainage layer. Avoid non-porous plastic sheets as a primary liner, as they trap water against the wood. You can use a durable plastic container *inside* the fabric-lined box for added protection, but it must have its own drainage holes. Regularly check the wood's condition and re-line as needed to keep your urban garden thriving for seasons to come.
