Besides its main locations in Dahlem and Kleinmachnow, the Julius Kühn Institute also has 13 other institutes. In 1898 a laboratory for testing new plant varieties and cultivation techniques was already set up the property that at that time was part of Domäne Dahlem. This approximately seven-acre test field still exists today and is the largest such field in Germany that is still being used as a test field in the middle of a large urban area. In 1905 the buildings on Königin-Luise-Straße were first put to use, meaning that Dahlem's location as a center for plant research is more than one hundred years old.
"I am very happy about the decision of the Budget Committee in favor of the Julius Kühn Institute in Dahlem. It was an important decision for anchoring research in Dahlem and at Freie Universität," emphasized Karl-Georg Wellmann, a CDU member of the Bundestag from the district of Steglitz-Zehlendorf. In recent years Wellmann had campaigned intensively for retaining the Julius Kühn Institute in Dahlem and for its close cooperation with Freie Universität.
