Four-tier vertical raised garden bed arranges herbs, flowers, vegetables, and fruits in stacked levels so you can plant densely in a small outdoor footprint while still reaching each tier for watering and care. The vertical layout helps improve sunlight exposure and air circulation compared with flat beds. Each container box is 6 in deep to hold soil and moisture, with drainage holes that let excess water escape. Removable, stackable plastic planter boxes and a metal frame with triangular layout and anti-slip foot pads support everyday use.
