The project was initiated by citizens. Beatrice van Tilburg is a neighborhood citizen who started the project and formed a community group, de Stichting de Tuinen van Mariahoeve. The municipality of The Hague has provided the land and filled it with new soil so that the community group was able to create the vegetable garden. (3). The community group, other neighborhood citizens, volunteers and children from the schools De Vuurvlinder and The British school do the maintenance in the community garden. (1,2,3). Resto Van Harte is a restaurant/NGO that organizes dinners at community gardens all over the country and also in the Mariahof and children from the primary schools help cooking when dinners are organized. (2). The 'Vereniging Ecologisch Leven en Tuinieren' (Association Ecological Living and Gardening, NGO) works together with the community group in organizing workshops and courses in the garden. Volunteers of this NGO can for example follow courses on basic ecological gardening. (2)

The ambition of the municipality of The Hague to become a climate neutral city in 2040 led to the 'Initiatievenbudget Duurzaamheid door Haagse wijken' (Budget for Sustainable Neighborhood Initiatives) of which the Mariohof is presented as one of the initiatives that the municipality supported. (7) However, it is unclear whether the municipality financially supports the community garden. It seems from the information that the municipality only donated the land and provided new soil. (6)
