Certificate program

Horticulture

The three-year certificate program takes a comprehensive approach to horticultural science, methods, and design. Students spend one day a week during the academic year attending all their courses: first year is taught on Mondays, second year on Tuesdays, and third year 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.
