Now you can enjoy all the advantages of raised bed gardening, plus the added benefit of watering weekly instead of daily. This stylish planter boasts two 4-gallon reservoirs that keep plants lush and green even in a drought. Its crisp lines and realistic wood grain look elegant on the patio, but it's tough enough to use in the garden, because it's made of crack-proof, fade-proof polypropylene. Nine square feet of growing area; a generous 12" deep so it's deep enough for root crops like carrots. Dual-action watering system keeps plant roots just moist enough without waterlogging them, and a water gauge tells you when to refill. Includes easy-fill funnel with cover and two styles of finials. Make the planter mobile with optional casters, sold separately (each planter requires four sets).
