Frankfurt’s Old Airfield revives its trees with a €100,000 ecological upgrade
A new ecological project is transforming part of Frankfurt’s Old Airfield. Work has begun to improve growing conditions for trees near the TowerCafé, giving their roots more space to thrive. The initiative is part of a wider plan to boost the site’s environmental value.
Asphalt removal started recently around five trees in the area. Instead of heavy machinery, suction excavators are carefully lifting old pavement and compacted gravel. This method protects the roots while clearing space for deeper growth.
Once the asphalt is gone, workers drill targeted openings into the densely packed gravel below. The soil is then loosened, enriched with nutrients, and rebuilt with a fresh substrate layer. These steps will help roots spread into deeper, healthier soil.
The project is funded by a €100,000 grant from the Kleinprojektefonds EEL, part of a larger €212,937 allocation for 23 new initiatives. However, the site’s military history could pose unexpected challenges during the work.
This effort aligns with the 2023 Old Airfield Development Plan, which aims to strengthen the area as a place for learning and relaxation. The changes will not only benefit the trees but also enhance the site’s overall ecological function.
The de-sealing project marks another step in the Old Airfield’s ongoing transformation. With improved root zones and enriched soil, the trees near TowerCafé should grow stronger. The work also supports the site’s long-term role as a green space for visitors and nature alike.
