Welcome to the Master Gardener Foundation of King County
Our Mission
The Master Gardener Foundation of King County (MGFKC) is a separate, 501(c)(3) nonprofit organization whose mission is raising funds to support the activities of the WSU Extension King County Master Gardener Program. The funds raised by our Foundation cover the many costs of operating the program, including plant clinic infrastructure and materials, demonstration garden supplies, and technology resources to suport educational outreach in our communities.
We Share a Purpose
The Foundation works in partnership with the WSU Extension Master Gardener program to secure funds that advance our shared mission of environmental stewardship in King County. Our fundraising supports Master Gardeners’ educational outreach for sustainable horticulture and integrated pest management.
