12″ deep soil box provides very adequate soil depth for all of your plants.
This very sturdy structure can be placed on your wood deck or concrete patio. You can also place it on the soil in your garden area, perhaps with a stepping stone block under each leg to keep it from settling deep into the soil surface.
The entire frame structure can be lifted, moved or relocated, by two people, once the soil box is emptied.? The four sides and the bottom of the structure can also be disassembled (simply by removing screws), if necessary.
Every single part is readily available at your local Home Depot hardware store or any good hardware store.
This product is professionally designed by mechanical engineers at Schultek Engineering, for many years of reliable service.
