About the Program

The three-year certificate program takes a comprehensive approach to horticultural science, methods, and design. Students spend one day per week during the 28-week academic year attending all their courses. First-year classes are taught on Mondays; second-year classes on Tuesdays; and third-year classes 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 at the Barnes Arboretum at Saint Joseph’s University, unless noted otherwise. The entrance is located at 50 Lapsley Lane in Merion, Pennsylvania.

All classes in the horticulture certificate program can be individually audited, space permitting, although some have prerequisites. Prices to audit are shown with each course below.
