URBAN PLANTER BOXES

Whether you need a liner for your metal urban planter box isn't a simple yes or no. It depends on your priorities: protecting the planter or ensuring optimal plant health. Metal planters, especially corten steel, develop a beautiful rust patina, but constant moisture can accelerate corrosion from the inside. A liner creates a crucial barrier, significantly extending your planter's life. For drainage, always use a liner with pre-drilled holes or add your own to prevent waterlogging. Without a liner, soil and moisture directly contact the metal. This can lead to rust stains, potential soil contamination from certain metals, and faster temperature swings that stress roots. For edible plants, a food-safe plastic or fabric liner is highly recommended. For decorative plants, you can forgo a liner if you accept the natural aging process and ensure excellent drainage with a layer of gravel at the bottom. Ultimately, using a liner is a wise investment. It protects your planter from premature rust, gives you better control over soil moisture and drainage, and creates a healthier environment for your plants to flourish in your urban oasis.
