Master Gardeners™ are highly trained volunteers who provide research-based, sustainable gardening information to backyard gardeners and professionals in their communities through education and outreach programs.
Have a gardening question? Ask a trained OSU Master Gardener™ volunteer!
Starting Tuesday, September 2, 2025, OSU Master Gardener volunteers will be onsite at the Columbia County Extension Office to help with all your gardening questions.
What you can bring to the Plant Clinic:

Our Master Gardener volunteers provide research-based answers for identifying weeds, diagnosing plant diseases, and managing insect pests.
