Is gardening associated with greater happiness of urban residents? A multi-activity, dynamic assessment in the Twin-Cities region, USA

•Household gardening supports high emotional well-being scores across 5 measures.•The type of gardening (ornamental v. vegetable) is linked to emotional well-being.•Self-identified, low income and female gardeners are associated with higher emotional well-being.•Companionship of household gardeners was not significant for emotional well-being. As cities seek to become more livable and environment-friendly, activities like bicycling, walking, and urban gardening (household and community-gardening) are receiving much attention. However, few field studies have measured well-being of urban gardening, particularly during household gardening. Our study develops protocols to measure emotional well-being (EWB) reported during household gardening, comparing it with other leisure and day-to-day activities. We also explore how gardening EWB varies across gardener type (vegetable vs ornamental), demographics, neighborhood type, and companionship during gardening. Using a recently developed app-based Day Reconstruction Method, EWB was measured across 370 participants in the Minneapolis-St. Paul Area, USA, wherein 118 (32%) reported engaging in household gardening. Innovatively, five measures of EWB were computed for each participant for each activity type: average net affect, average happiness, average meaningfulness, the frequency of experiencing peak positive emotions (happiness and meaningfulness). Among all three average EWB measures, gardening is among the top 5 out of 15 activities assessed, and, is not statistically different from biking, walking and eating out. All four of these activities fall behind other leisure/recreation activities, which ranks first. For frequency of experiencing peak happiness, only other leisure/recreation activities were statistically higher than all the remaining (14) activities. Average net affect of gardening was significantly higher for vegetable gardeners (vs ornamental), for low-income gardeners (vs higher income) and for women. Companionship while gardening at home, race/ethnicity and urban versus suburban location showed no significant difference. Livability and equity considerations based on these EWB findings, and their impacts on urban food plans, are discussed.
