About the Program

The three-year certificate program takes a comprehensive approach to horticultural science, methods, and design. Students attend their courses for a full day each week throughout the 28-week academic year. First-year courses are taught on Mondays; second-year courses on Tuesdays; and third-year courses on Wednesdays.

Upon successful completion of the program, students receive a certificate of merit in horticulture. Students and graduates may elect to sit for the Pennsylvania Certified Horticulturist exam.

Horticulture classes are held in the Barnes Residence at the Barnes Arboretum, 300 North Latch’s Lane, Merion, PA 19066, unless noted otherwise.
