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.
