BERLIN, GERMANY - AUGUST 04:  Members of the Bauerngarten Havelmathen gardening colony harvest potatoes and beans in the Bauerngarten Havelmathen (Farm Garden Havelmathen)  urban garden in Spandau district on August 4, 2013 in Berlin, Germany. For a small yearly sum local residents can plant their own vegetables and other plants at Bauerngarten Havelmathen in round shapes, and the garden is one of many that have sprung up in recent years in Berlin as more city dwellers turn to gardening as an alternative to store-bought produce.
