The Oregon State University Extension Master Gardener™ program educates Oregonians about the art and science of growing and caring for plants. In the Portland Metro area, we are in Multnomah, Washington and Clackamas counties and train hundreds of Master Gardener volunteers. OSU Extension Master Gardeners are volunteer educators, neighbors, and on-the-ground researchers who serve their community with solid training in science-based, sustainable gardening and a love of lifelong learning.
