Crisp white with straight lines and a modern design, the DuraTrel Split Level 4' x 8' Raised Planter Bed makes growing vegetables look like a refined, beautiful, and clean affair. The two levels are designed for different types of plants: put your root crops like carrots and potatoes on the top deep bed, and grow your shallow-rooted peas and spinach on the bottom. You'll have fresh, organic produce at the end of the season without needing to till and season a section of your lawn. The 4 x 4 inch posts sink six inches into the ground for added stability. This planter bed is made from vinyl PVC with a UV stabilizer so it won't rot, crack, or fade even after years of exposure to the elements. All Duratrel products come with a 20-year limited manufacturer warranty. .
