The 12' × 12' Jumbo-U Animal Barrier Garden provides approximately 102 sq ft of expansive growing space, designed for high-output gardening with room to grow both outward and upward. The integrated animal barrier protects crops from rabbits and other ground-level pests while also functioning as a sturdy trellis for vining plants such as tomatoes, cucumbers, peas, beans, squash, and melons.

Vertical growth along the perimeter opens up the interior planting area for leafy greens, herbs, peppers, root vegetables, and fruiting crops, allowing for more efficient use of space and higher overall yields.

Each stacked level of the garden bed requires approximately 46.8 cubic feet of soil per 5.5" height, creating deep, well-draining soil conditions that support strong root development, nutrient retention, and intensive planting across a large, protected footprint.

Each Capped Composite Garden Board features a hollow-profile design that traps air to create a natural insulating layer around your soil. This built-in insulation helps keep root systems cooler during hot summer months and warmer as temperatures drop in the fall, promoting more consistent growing conditions.

The GardenBLOX Stack & Extend System is a modular raised garden solution built from stackable capped composite boards and precision-engineered pivoting brackets. These components function as versatile building blocks, allowing gardeners to design, expand, and reconfigure garden beds to fit virtually any space.

The system’s flexible design makes it easy to stack boards for added soil depth, extend layouts over time, or create custom shapes as your garden evolves. Whether starting with a small bed or building a larger configuration, GardenBLOX adapts to changing needs season after season.

Designed for demanding outdoor environments, the capped composite boards feature a protective outer cap that seals the composite core against moisture, soil contact, insects, and UV exposure. This advanced construction helps prevent the common failure points of traditional garden beds, including rot, warping, cracking, and splintering.

Because the material maintains its strength, dimensional stability, and appearance through years of weather exposure and repeated planting cycles, the system is backed by a 20-year warranty, delivering long-term reliability and added peace of mind for gardeners.
