Stress management for office workers has become a critical issue in recent years, with office greening gaining attention as a potential solution. Recent studies suggested that setting plants on individual desks can improve office worker's mental state. However, the burden of individually maintaining for desk plants poses a significant challenge. This study introduced a greening method where workers can freely exchange desk plants, eliminating the need for individual maintenance (self-managed system). This study evaluated the psychological effects of the self-managed system and compared them with those of the conventional fixed system, which requires individual plants management. The results indicated that different methods of greening had distinct effects on participant's emotions, as measured by the Profile of Mood States 2 (POMS 2), as well as on their subjective evaluations assessed using the Visual Analog Scale (VAS). Based on the State-Trait Anxiety Inventory Y-2 (STAI Y-2), participants were further categorized according to their levels of trait anxiety. The results revealed that the psychological effects of greening methods differed depending on individual anxiety tendencies. This suggested that tailoring greening systems to account for personal psychological traits can optimize their effectiveness. These insights highlighted the potential of innovative greening methods to enhance office environments, reduce stress, and support worker well-being.
