So, do plants need soil for their survival? Surely this was the great question that Patrick Blanc asked himself when he prepared to inquire more about the matter. It was then that he began his studies in tropical botany, completing a thesis on the adaptation of vegetation in the tropics. With her he was awarded by the French Academy of Sciences in 1993. During those years and later, Blanc developed the concept of vertical garden.
The answer to that question was clearly no. For plants, water and its minerals are essential. The earth no. His vision and experience have provided him with an infinite number of architectural projects that include vegetation in forms and places that nobody could have ever imagined; facades, walls and interior vertical panels for example.
The system basically consists of a chassis that form a metal structure to hang. In this way, a new layer is created and we free from affectations to the original wall, since it is possible that the roots end up damaging this, as has happened in historical buildings and temples in a natural way.
The structure is nourished by a vegetable peat where all the roots are going to stop. This peat is rich enough that, with the help of water and its minerals along with sunlight, they can grow in a correct way.
