The ongoing academic debate shows that urban community gardening has diverse governance models with differing roles for governmental organizations, NGOs and local communities. However, the perspective of community gardens governed by the involvement of institutions is rarely explored in academic research. This paper use a two-case study approach to explore the relations between community gardens and cultural institutions. We first identify factors that promote and impede the functioning of community gardens in partnership with cultural institutions. Next, we recognize initial governance models for selected case studies. Finally, we try to identify any changes in these governance structures, depending on the different stages of garden development and determine the reasons behind them. The results show these gardens are characterized by a changing governance model, shifting towards a top-down model, in which community members have no influence on strategic decisions. The involvement of cultural institutions in running community gardens is not assessed in a solely positive light. Although it facilitates their longevity, at the same time it may disempower their viability.
