Making a Difference

We serve our King County gardening community in 39 Plant Answer Clinics and 13 demonstration and outreach gardens, through online classes and workshops, reaching over 15,066 people at 595 clinic events in 2023. Our 512 Certified Master Gardeners spent over 20,693 hours in service.

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 4,252 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. In 2023, we responded to over 745 emails related to home gardening.

Your contributions help our program. Please support us.
