When using metal urban planter boxes, it's essential to install a liner to prevent direct soil contact, which can cause corrosion, rust, and damage to the metal over time. A good liner acts as a barrier, protecting the box while ensuring healthy plant growth by managing moisture and drainage. For optimal results, consider materials like heavy-duty plastic (such as HDPE or pond liner), which is durable and waterproof, or landscape fabric, which allows for breathability and drainage while blocking soil. Alternatively, rubber liners or recycled composite materials can be eco-friendly choices. Always ensure the liner has adequate drainage holes to prevent waterlogging, and secure it properly to avoid shifting. This simple step extends the life of your planter boxes and supports thriving urban gardens.
