On Monday, June 8, 2026, Berlin’s Senator for Urban Development, Christian Gaebler (SPD), visited the Späth’sche Baumschule site for the first time; according to current plans, residential housing could be built there. Among those participating in the site visit were Lars Düsterhöft and Julia Dittmar of the SPD, District Mayor Oliver Igel (SPD), the managing directors of Späth’s Nursery, Laura Lichtenheldt and Susanne Schmohl, Karoline Leu, former managing director Holger Zahn, Susanne Schneider-Kettelför, who handles public relations for Späth’s Nursery, Dr. Anika Dreilich from the Humboldt University Arboretum, and Gesine Schaumann from Weltacker Berlin e. V.
In the spring, initial plans for a possible development project had come to light. In response, the management of the Späth Nursery launched a petition against the proposed plans. The petition has since closed, having gathered nearly 22,000 signatures. The high level of interest demonstrates the importance that many people place on the historic, 300-year-old tree nursery and its educational and research programs.
During a visit by Senator for Urban Development Mr. Gaebler, discussions focused on the development of a residential neighborhood with approximately 2,500 apartments, a portion of which is intended to be affordable housing. At the same time, the Späth Nursery emphasized its commitment to preserving the site’s role as an environmental education center in the long term.
The next steps call for project planners commissioned by the Senate to revise the structural and land-use concept in collaboration with Berlin’s Senator for Urban Development. Before this concept is submitted to the Senate for further decision-making, the Späth’sche Baumschule will also have the opportunity to review it and provide feedback. Subsequent negotiations will then take place with the insolvent company that owns the site. This marks the start of the planning process for developing a concept for areas not owned by the State of Berlin.
As things stand, no changes are expected in the near future. In the coming years as well, children from Treptow-Köpenick and Neukölln, school classes, community groups, and many other interested individuals will be able to visit the Weltacker and experience educational programs on sustainable agriculture and nutrition free of charge.
We are closely monitoring further developments and will provide updates as soon as new, confirmed information becomes available.
