Using Corten in the Garden
To bring more modest Corten accents into your garden, consider the wide range of premade planters, fire pits, benches, and raised-bed boxes widely available online and at retailers.
Using Corten on a larger scale is best turned over to professional designers and contractors, particularly when drainage, weight-bearing, and soil-retention issues are involved. Larger installations are typically manufactured off-site.
Keep in mind the material’s vulnerabilities when choosing where and how to use it: The metal’s corrosion-resistance is not as great in salt air or when placed in constant contact with water. Be prepared to provide special drainage for walls grounded in heavy soil, and keep in mind that runoff from the metal can stain adjacent surfaces, such as concrete.
