Urban gardens are focal in metropolitan social-ecological infrastructure and yet they are spaces often threatened by urban development. In Berlin and Warsaw, major urban changes have prompted citizens to alter their attitudes toward the use of existing garden areas. This study tackles the socio-spatial phenomena of emerging grassroots projects and practices jointly implemented by groups of allotment and community gardeners, which are instrumental in envisioning new forms of common management and protection of garden spaces along urban transformations. The article investigates how cooperation between gardeners of different backgrounds influences allotments’ patterns of property and public accessibility. The focus is on a possible change of perspective regarding the use of closed allotment structures and the conceptualisation of a new form of hybrid urban landscape: an integrated garden. Our findings fit into the general debate on gardens as commons and new forms of green space selfgovernance.

城市花园是大都市社会生态基础设施的焦点，但它们是经常受到城市发展威胁的空间。在柏林和华沙，重大的城市变化促使市民改变了对现有花园区域使用的态度。本研究解决了由分配和社区园丁团体共同实施的新兴基层项目和实践的社会空间现象，这有助于设想城市转型过程中花园空间共同管理和保护的新形式。这篇文章调查了不同背景的园丁之间的合作如何影响分配的财产模式和公共可达性。重点是关于封闭分配结构的使用和混合城市景观新形式的概念化：综合花园的观点可能发生变化。我们的研究结果符合关于花园作为公地和新形式的绿色空间自治的一般性辩论。
