Allotment gardening as element of green infrastructure and integral part of urban agriculture supports the city’s sustainable development and builds urban resilience. The COVID-19 pandemic provided an opportunity to revisit allotment gardening in a situation of unprecedented health crisis. Therefore, this study aims to recognise the importance of allotment gardens during the COVID-19 pandemic in Poznań (Poland), a city with a ‘famine of plots’ observed for years. A survey was conducted among allotment holders who had acquired plots during the course of the pandemic and in-depth interviews were conducted with the president of the Polish Allotment Federation of Poznań and the managers of the allotment gardens wherein we had identified the highest proportion of new allotment holders. Information was collected during field research, also using available statistical data. The methods used included desk research and a case study, interviews and a survey. The results of the study show that the pandemic caused a renaissance in allotment gardening. The increased interest in allotments triggered an increase in their price, thus further restricting access. A generational change in the allotment community was also noted, with young people appearing on allotments. However, the survey showed no change in the use of allotments: recreation is still their dominant function, with allotment holders focusing on cleaning and renovation work. For new allotment holders, the plot was a green refuge in times of isolation, a place for contact with nature, loved ones and family, and a safe space for relaxation. Our research indicates that allotment holders also appreciated its positive impact on their physical and mental health.. Moreover, the study indicates that despite the long-standing shortage of allotments in the city, only restorative allotment gardens are being created.
