The site, formerly used as a show garden and covering approximately 5,700 square meters, was made available for community gardening by the city of Karlsruhe in 2022. In addition to preserving the existing structures, the site offers numerous opportunities for horticultural use and more. A natural pond is a particular highlight.

In January 2024, the association "Mitmach-Garten Ostring e.V." was founded by people interested in urban gardening, biodiversity, and social interaction, and who are committed to ecological and sustainable management. Some of our members have extensive gardening knowledge, while others have less; our shared focus is on natural gardening practices.

Our community garden on Ostring is a vibrant place for encounters, culture, and experiencing nature, where people of all ages and backgrounds garden together, learn, and exchange ideas. Working together in the garden is what defines our association, and the willingness to participate is very important to us. We carry out activities together, such as mowing the meadows or building a comfortable seating area for shared breaks.

Regular meetings are held for planning and coordination. Anyone interested is warmly invited to learn more and get involved.
