Absolutely! Using a liner inside your urban planter boxes is a highly effective and common practice to prevent soil from washing out through the drainage holes. It acts as a permeable barrier, allowing excess water to escape while keeping the soil in place. For best results, choose a material like landscape fabric or a coarse, breathable geotextile. Avoid non-porous materials like solid plastic, as they can lead to waterlogged soil and root rot. When installing, simply line the bottom and sides of your planter box, ensuring you cover the drainage holes. Then, add a layer of gravel or small stones over the liner before adding your potting mix. This combination further improves drainage and stability. Remember, the key is balance—you want to retain soil without creating a swamp. With a proper liner, your plants will thrive, and your clean-up duties will be much easier.
