Stacked into five staggered tiers this vertical raised garden bed maximizes growing space within a small footprint. Each tier holds soil for strawberries herbs lettuce or flowers while built-in casters let you roll the planter to chase sunlight or move it indoors during frost. Drainage holes release excess water and tier dividers keep root systems separated. The steel frame resists rust under outdoor exposure and supports the full soil load across decks balconies patios and small backyards.
