There are almost 17 million gardens in Germany – their combined area is larger than that of all the country’s national parks put together. Actress and keen gardener Maria Furtwängler travels the length and breadth of the country to find out: what can we all do to save hedgehogs, blackbirds and bumblebees? She meets nature lovers in Berlin’s backyards and on green roofs, in allotment gardens in Saxony and even in gravel gardens in the Rhineland. With a touch of humour, the film shows how species conservation can be achieved right on our doorsteps.
