We also worked on living walls. First, we removed the old modules from the wall. We noticed that the old environment created a great living surroundings for small insects which increased the eco-biodiversity.
After taking all the modules off the wall, we cleaned them in prepared for new plants. We filled the module with soil(half volume of the module size) and planting the plants. After put fertilizer on top layers of each module, we filled the module with extra soil. At last, we settled 100 modules.
