Progressive climate change, associated warming and droughts will affect the vegetation in our cities. In the "Mediterran Garden" Matthias Fritsch wants to counter climate change positively. He is experimenting with crops from the European south of Europe and is trying to establish plants such as figs, olives and carob trees in suitable locations in the German capital. These plants can withstand light frost if they are not too exposed to the weather, e.g. on wind-protected southern walls.

If one looks at the climate history of Europe, then there were already some warm centuries in the Middle Ages, in which e.g. wine dominated up to much further northern regions, than it is typical today.

If the experiment is successful, after a few years of dry summers and mild winters, fruits would be harvested that normally grow in much more southern regions. The bigger obstacles at the moment do not come from the climate but from the careless "weed-removal work" of the green area offices or ignorant&badly trained gardeners.

Update 2023
Unfortunately, the carob saplings did not survive the few nights with extreme temperatures. While in the first year they were still protected with a greenhouse flask, which only froze the tips of the shoots, in the second year the ground froze so deeply that even the still young roots were damaged.
