Our Mission

OSU Master Gardener Logo

The Oregon State University Master Gardener™ Program is an Oregon State University (OSU) Extension Service program that educates Oregonians about the art and science of growing and caring for plants. This program also facilitates the training of a highly educated corp of volunteers. These volunteers extend sustainable gardening information to their communities through education and outreach programs.

What We Do and Where We Work: In 29 counties across Oregon, Master Gardener volunteers answer gardening questions at OSU Extension offices, at community Farmers’ markets, and at Master Gardener events. Volunteers create and manage demonstration gardens, school gardens and community gardens. They host garden tours, workshops and classes in their communities.
