Flexible and practical, this set of four raised planters is molded from weather-resistant polyethylene for all-season durability. Arrange them into square or rectangular beds, or stack them higher for deep-rooted plants. A built-in self-watering disk and drainage holes keep moisture consistent with minimal effort, and the elevated height eases bending while discouraging ground pests. No tools are needed to assemble, and each planter measures 16 by 16 by 17.5 inches.
