The aim of this study is to explore the possibility of using the school garden in primary education, with an emphasis on the subject Science, and to examine and present the experience in primary schools that have a school garden. The results of the research show that the school garden can be integrated through many topics in primary education, especially in the teaching of Science in the 2nd and 3rd grade when students observe their homeland, and in the 4th grade when they need to notice the growth and development of living beings. Work in school garden is possible to correlate with other subjects, but also to include expected student competencies from cross-curricular topics. The study presents three school gardens from primary schools in the lowland homeland. All schools try to connect the curriculum as much as possible with the work in the school garden, because such a form of teaching arouses the exceptional interest of students and mutual satisfaction. This is evident through winning the Golden Charter for the most beautiful school garden, but also with the diverse range of products offered by schools. The success of good organization of cooperatives is shown by the cooperation with the local community and numerous realized projects.
