Gardening Classes & Workshops

Cultivating Knowledge Anywhere – It’s never been easier to learn about gardening from the comfort of home! Fees from our various gardening classes are used to fund local Master Gardener activities in King County.

Growing Groceries Classes – The Growing Groceries (GG) lecture series has been part of the King County program since 2019. In these classes you will learn best practices for growing fruits and vegetables in Western Washington. Class content is based on current science and is appropriate for the time of year and climate zones in our area. Ideal for the beginner to intermediate home gardener, classes are taught by speakers who can share their own experiences and refer to research from WSU Extension publications about the art and science of growing food. Classes are held via Zoom on selected Wednesdays, January 31 through the fall, from 7:00pm to 8:30pm. Register for individual classes or series workshops at a discount.

BDG Workshops – The Bellevue Demonstration Garden (BDG) workshops offer general gardening knowledge and skills for all ages and skill levels in a convenient online format. Workshops introduce gardeners to a variety of plants and growing techniques proven successful in the Pacific Northwest, with an emphasis on ornamental plants, landscape planning, and pollinator habitat.  Workshops are held via Zoom on selected Saturdays each month, from January 20 through October, 9:30am to 10:30am.
