Supporting King County Master Gardeners since 1984

Investing in a sustainable future

Welcome to the Master Gardener Foundation of King County

The Master Gardener Foundation of King County (MGFKC) is a 501 (c)(3) nonprofit founded in 1984 as a charitable and educational nonprofit organization. All King County Master Gardener volunteer activities are funded through MGFKC which is a member of the Master Gardener Foundation of Washington State (MGFWS).

In partnership with the King County Master Gardener Program, the Foundation advocates for Master Gardeners as they learn and teach science-based home gardening to the public in King County. Please donate to the foundation today to support these volunteers in our county.

Making a Difference

We serve our King County gardening community in 37 Plant Answer Clinics and 13 demonstration and outreach gardens, through online classes and workshops, reaching over 15,800 people in 2022. Our 620 volunteers spent over 26,200 hours in service in 2022.

We have demonstration gardens throughout King County. We help fund capital expenditures to improve the productivity of our demonstration and outreach gardens. Last year, we donated over 4000 pounds of produce to local food banks in King County to help address food insecurity.

We have gardening events in our youth gardens at Magnuson Childrens Garden, Tribal Life Trail, Bellevue Demo Garden childrens garden, and Shorewood High School. This education serves to connect young people with the world around them and teach how plants grow and thrive.

We connect with home gardeners in urban, suburban, and rural areas. We offer free advice through our Plant Answer Clinics at farmers’ markets and stores and our online email clinic. We hosted over 700 clinics in 2022 and responded to over 1100 emails related to home gardening.

Your contributions help our program. Please support us.
