Gardening in the city brings joy, but strong winds on high balconies and rooftops can turn it into a challenge. Choosing the right planter box is crucial for success in very windy locations. The best planters combine weight, stability, and smart design to withstand gusts.
First, prioritize weight and low profiles. Heavy materials like concrete, fiberstone, or thick, reinforced ceramic add inherent stability and are less likely to tip over. Opt for low-profile, wide planters over tall, narrow ones, as they have a lower center of gravity. For larger trees or shrubs, consider substantial wooden troughs or composite planters.
Secure attachment is non-negotiable. Look for planters with pre-drilled drainage holes that can also be used for anchoring. Use sturdy brackets, galvanized screws, or even discreet weatherproof straps to secure the planter to railings, walls, or the floor itself. Placing heavier planters against a wall or in a corner provides additional wind protection.
Material choice is key. Avoid lightweight plastic or thin metal that can buckle. Durable, UV-stable polyethylene resins, powder-coated steel, and rot-resistant cedar are excellent, resilient options. Ensure excellent drainage to prevent waterlogged soil, which adds dangerous weight and can freeze. Use a well-draining potting mix and elevate the planter slightly with feet.
Finally, strategic planting helps. Use wind-tolerant plants like ornamental grasses, sedums, and dwarf conifers. Planting densely creates a collective root mass that helps anchor the soil. For taller plants, install internal stakes tied to the planter for extra support.
By selecting heavy, low-profile planters, securing them properly, and choosing durable materials, you can create a thriving urban garden that stands up to the wind.
