Despite an emerging literature on guerrilla gardening as a political practice in public spaces, with few exceptions, these accounts theorise it as working against many corporate and bureaucratic forms of power. Using the example of ‘F Troop’—a group of gardeners operating on a site in an English midland city—this paper focuses on the practices of urban guerrilla gardening in order to illustrate that these are perhaps not as ‘resistant’ or ‘celebratory’ as previous accounts have suggested. Rather, this paper draws on ethnographic data to focus attention on the micro politics of garden activism, arguing that the social backgrounds and motivations of those involved in guerrilla gardening and their relationship with other users of the space surrounding the dig site are also important—but largely underacknowledged—aspects of guerrilla gardening.
