Certificate program

Horticulture

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.
