Master Gardener Training

How do I become a Master Gardener?

Master Gardeners (MGs) are volunteers trained by OSU Extension Service agents and specialists. To become an OSU Master Gardener, you must complete the training program, pass a final examination following training, and volunteer a specified number of hours of public service through the Master Gardener program.

What will I learn?

Through the Master Gardener Training program volunteers receive training in botany, soil science, insect and disease identification and control, care and culture of ornamental plants, small fruits, lawns, home orchards and vegetables, and diagnosis of plant problems.

When and Where?

In 2016, classes will be held early January through mid-March on Wednesdays from 9am to 4pm.
