We compare interviews with 30 new community gardeners in Denver, Colorado and Montpellier, France, using Self-determination theory, a general theory of motivation, to determine how new community gardeners may or may not have felt motivated based on psychological needs of autonomy, competence, and relatedness. Relatedness as a motivational feature carried through the interview data at both sites. Participants’ success or failure to relate to other gardeners was a major influence for how autonomous and competent as a community gardener they expressed feeling. As the evidence grows that community gardening is beneficial for health and wellbeing, our findings are critical to understanding how community gardening could serve as a health promotion strategy. With the presence of ongoing, friendly support from others, more individuals may adhere to this socially connective, nature-based practice.
