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.
