This study aims to examine the impacts of community gardening on the daily life of residents and the management organisation of pandemic prevention in the context of the COVID-19 pandemic, a major public health scourge in 2020. The research team applied a participatory action research approach to work with residents to design and implement the Seeding Plan, a contactless community gardening program. The authors carried out a study to compare the everyday conditions reflecting residents' mental health of the three subject groups during the pandemic: the participants of the Seeding Plan (Group A), the non-participants living in the same communities that had implemented the Seeding Plan (Group B), and the non-participants in other communities (Group C). According to the results, group A showed the best mental health among the three; Group B, positively influenced by seeding activities, was better than Group C. The interview results also confirmed that the community connections established through gardening activities have a significant impact on maintaining a positive social mentality under extraordinary circumstances. From this, the study concluded that gardening activities can improve people's mental health, effectively resist negative impacts, and it is a convenient tool with spreading influence on the entire community, so as to support the collective response to public health emergencies in a bottom-up direction by the community.
