It is hard to predict how climate change will affect mediterranean areas, but we may very well have to face hotter, drier or longer summers. We shall thus need to be increasingly careful about our use of water and shade creation in the garden. Water and shade is essential for life on earth, and it is a limited and valuable resource in the mediterranean climate regions of winter rain and long dry summers. Many dry-climate plants are in fact easy to grow if we respect the conditions of their native habitat, but become extremely capricious as soon as we try to water them in summer. Irrigation during our blazing summers generally proves fatal to them. An evident solution is to create artifitial or natural seasonal shade.
