What counts as CE for Extension 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 Email Clinic, workshops with Master Gardener’s and expert horticulturalists, online learning through WSU Extension and our websites, Diagnostics Lab and more.
