Classes meet on Tuesdays from 5:30 to 8:30 p.m. (except The Science of Plant Propagation, and Zooms).

Each class is 12 hours of classroom time, plus a final project (except Landscape Design which is 21 hours).

Level I courses cover material essential for a foundation in good gardening practices.

Classes are designed sequentially beginning in September and running through April.

The Level I Certificate requires the completion of all seven Level I core curriculum classes, assignments, and at least 15 Garden Practicum hours.
