The Barnes Foundation's Arboretum School has been educating students in the field of horticulture since its creation under Laura Leggett Barnes in 1940. Experienced instructors integrate a combination of 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 that meets one day per week, students receive a certificate of merit in horticulture.
