Are cast iron outdoor tree boxes suitable for use in rooftop gardens?
Cast iron outdoor tree boxes can be a stylish and durable option for rooftop gardens, but their suitability depends on several factors. Known for their strength and longevity, cast iron planters withstand harsh weather conditions, making them ideal for exposed rooftop environments. However, their significant weight requires careful consideration of the roof's load-bearing capacity. Proper drainage and rust-resistant coatings are essential to prevent water damage and corrosion. When chosen wisely, cast iron tree boxes add elegance and structure to rooftop gardens, blending functionality with timeless design. Always consult a structural engineer to ensure safety before installation.
