2018 Urban Micro Gardens (Milano)
Unpretentious, stubbornly resisting traffic and pollution, they strive in what may appear a very hostile environment and create self-sufficient microcosms of greenery.
They do not need to be attended, watered, manured or pruned.
In fact, they are hardly noticed at all, but for those who can see they appear as welcome oases in a world of asphalt and stone.
To create them, all you require is to dig a hole in the street pavement or in the sidewalk, when nobody is around, minimizing the risk of being splattered by a passing car.
