Program details
Oregon State University Extension Master Gardener volunteers are neighbors, friends, and family who you can go to for garden advice that is grounded in science and locally relevant. We are garden educators and on-the-ground community scientists. Master Gardeners receive extensive training and complete a university-taught course in topics including botany, pest identification, soil management, and diagnosing plant problems, to name a few.
Sliding scale fee and scholarships available.
Master Gardener Training
To become a certified Master Gardener, participants complete 40 hours of training classes and 40 hours of Master Gardener volunteer service. Anyone interested in horticulture and becoming a community educator can apply to the program.
