Clackamas County  Master Gardener Chapter

We are a trusted resource of Oregon State University (OSU) research-based information for sustainable gardening, serving residents of Clackamas County and the Portland Metro region.

We continuously refresh our knowledge to stay informed of current gardening issues and new research findings. We actively reach out to our community in sharing our knowledge.

We support individuals and groups, sharing our interest in gardening through scholarships, grants, and the annual Spring Garden Fair.

We support the OSU Master Gardenerâ„¢ Program and Extension Service.

We hold free lectures on the 2nd Monday of each month (except July and August) at the Milwaukie Center (5540 SE Kellogg Creek Drive in Milwaukie).  Lectures are open to the public and start at 7 p.m.  Each lecture features an expert presentation about an interesting gardening topic. If you have a physical disability that requires special considerations in order for you to attend any event/activity, please notify the metro Master Gardener program at 503-655-8631 or send an e-mail to
