The King County Master Gardeners in cooperation with Bellevue Parks & Community Services manage the Lake Hills Greenbelt Urban Demonstration Garden also known as Bellevue Demonstration Garden. Established in 1984, this urban demonstration garden has grown from a single P-Patch surrounded by blackberries on a steep, rock-filled slope to the flourishing garden it is today. The mission is to provide public education in gardening and home horticulture, founded on resources from Washington State University, and to create a solid learning experience for the volunteers. The Bellevue Demonstration Garden demonstrates good gardening practices in a typical urban setting and provides Master Gardener volunteers a practical hands-on educational resource. The garden includes a complete MG Diagnostic Plant Clinic, Master Compost Center, Greenhouse Operations, Children’s Garden, over 40 demonstration beds and gardens.  Events include a Saturday on-line Workshop series and a Wednesday Kids in the Garden series, both for the general public and presented from January through October.  Two other major events are the Spring Plant Sale in May and Harvest Festival/Plant Sale in September. Hours: open from dawn to dusk.  Wheelchair accessible.
