Corten Steel Modular Raised Bed, 2' x 4' (17.5" D)

17.5" deep for all your favorite plants! Stick with one of our two standard sizes, or create a raised bed of your own ideal length by tacking on an Extension or two . Add 2 of our innovative Self-Watering Inserts to extend time between waterings and ensure consistent moisture all summer long with 10 gallons of self-watering capacity. Corten steel is a unique and durable weathering steel that develops a protective patina of rust over time that safeguards the base metal from corrosion. The steel arrives in its natural grey state and will build its patina over a period of weeks. (If you can't wait for that rustic appeal, our quick-aging recipe can help you achieve your perfect patina in one afternoon.) For best results, we recommend filling with 15 bags of our premium potting mixes: Organic Raised Bed Mix (20 qts.) Potting Mix (20 qts.) Organic Potting Mix (20 qts.)
