The Barnes Foundation's Horticulture Education Program has been educating students in the field of horticulture since the creation of the Arboretum School under Laura Leggett Barnes in 1940. Experienced instructors integrate classroom lectures, field study, hands-on practice, and visits to other gardens in this comprehensive program incorporating science, design, and plant knowledge. Upon successful completion of the three-year program, which meets one day per week, students receive a certificate of merit in horticulture.
