To create a more sustainable society it is important to invest in proenvironmental behaviour, such as green gardening. This research has taken steps in understanding the green gardening intentions and behaviours of the inhabitants of Leiden, using data retrieved by students in 2021 in collaboration with the municipality of Leiden. To investigate this, the model of the theory of planned behaviour (Ajzen, 1991, 2020) has been used, including the variables attitude, subjective norm and perceived behavioural control. Applying anticipated guilt as a moderator, this study investigated if this emotion can help to close the gap more between intention and behaviour within the model. The results (N = 126) showed that the theory of planned behaviour significantly explains green gardening intention and behaviour. However, anticipated guilt did not influence the relationship between intention and behaviour. Nevertheless, the findings contribute to sustainable gardening research and calls for future research on positive emotions, such as anticipated pride. This study can be used for the shaping of marketing campaigns to encourage green gardening.Show less
