King County Master Gardener Education Events

NOTICE – Message regarding education event cancellations.
In accordance with the latest guidelines from the King County Department of Health regarding COVID-19 we are suspending in-person MG gatherings until further notice. We are asking those who have coordinated in-person CE events to cancel, reschedule, or if feasible, to hold those events online. Watch this page for event updates.

What counts as CE for Master Gardeners? Those classes that will improve a volunteer’s knowledge and skill base for performing work as a horticulture adviser and serving as a resource on issues of sustainable gardening for home gardeners.

A large part of the Master Gardener experience is sharing our knowledge with others and continuing to learn with other members. Learning takes place in many ways, and the Master Gardener Program is offering more ways to learn and keep us current than ever before including its community gardens, plant clinics, Ask-a-Master-Gardener e-clinic, workshops with Master Gardener’s and expert horticulturalists, online learning through WSU Extension and our websites, Diagnostics Lab and more.


Some King County Master Gardener intern training classes are open to the veteran Master Gardeners. These classes provide CE opportunities to Master Gardeners to refresh their learning and keep current with information from WSU. The 2020 training classes will be held at the UW Center for Urban Horticulture from January through March. KCMGs will receive an email regarding sign-ups for open training classes.
