Located in Athens, Greece, we are doing a scientific research in the University i am attending in green roofs, where we have planted 5 species, one being Sedum sediforme and the rest being other Mediterranean species. We are testing the effect of the substrate depth and the substrate nutrition. So far we have observed that all the sedum sediforme plants we have planted have eventually been subsided. Do you believe that it is because of the competition with the other plants or because of another parameter?
