The specific case of home gardening practices is particularly relevant when discussing lifestyle habits and ecological transition, due to the wide range of positive and negative environmental externalities private gardens may generate. However, existing studies usually focus on restricted areas, mostly at a city scale. We provide an original empirical contribution to the literature on individual and institutional drivers regarding ecological transition by exploring the variations of individual behavior between European countries with an appropriate econometric approach. Using a European database (Eurobarometer 83.4), we highlight several interesting results regarding Europeans’ adoption of sustainable gardening practices, more particularly on the role of socio-demographic drivers, urban or rural residential location and access to trustworthy biodiversity-related information. In conclusion, we provide recommendations for the design of dedicated public policies, specific to a national or local level of decision.
