Since 1975, Dalen Products has been dedicated to providing homeowners with the professional-grade products they need to cultivate a healthy, breathtaking garden. Our passion for gardening began with our founder, Neal Cadwell, who first developed products to establish his own beautiful garden on a plot of land that everyone else in the area had already given up on. Since then, we have put this passion to work creating high-quality, innovative gardening solutions that are designed to help gardeners tackle their most pressing challenges. Make square foot gardens easy with a modular, customizable sq ft raised bed kit! For safety purposes, we recommend not stacking panels over 2 high. This product is intended to be used as a raised bed garden box, and is not designed to be a retaining wall, etc. However, the product is strong and designed to be expanded infinitely. Additional panels are sold by the piece. Create the sq ft raised bed you want, whatever the configuration!
