At this garden you can grow vegetable and herbs, and flowers. The original design will be not only useful, but also decorate the balcony.
The device may beds suggested by the shape of stairs. Anyway, it looks like the base of the structure, attached to the wall: two vertical boards with filled, like steps, rungs. On them — a cascade of plant boxes.
Most interesting is that the boxes are not fixed, they are removable. How do they stay on the “ladder”? Thanks to a little secret in their design.
In appearance the boxes as the boxes. That’s just to the rear of their more attached plate size just above the wall—it performs the function of a kind of bracket. This free mount allows you if necessary at any time to remove the boxes for plantings or swap them.
