The purpose of the research presented in this article was to highlight the opinion of primary school teachers at Alexandru Davila Secondary School in Pitesti, Romania, involved in the Erasmus + project entitled Wild! The wild garden for learning and development, regarding the possibility of carrying out non-informal activities in the wild garden, taking into account the proposed activity models. The questionnaire was the research method applied to the 12 professors participating in the implementation of the project, in order to achieve the proposed goal. After analysing the answers of the respondents, we found that the teachers carried out non-formal outdoor activities with students from all classes of the primary cycle, among which we mention the following: sowing or planting some plant species in the wild garden, observing the life cycle of different plant species, observing the external composition of different species of invertebrates and vertebrates, carrying out experiments and building herbariums or collections of variously coloured leaves in the specific colours of autumn. From the models of activities proposed in the project, the teachers mentioned that they selected only some activities for students in a certain class, and will repeat or perform other non-formal activities in the wild garden in the coming school years.
