We are excited to be resuming favorite Master Gardener volunteer opportunities in the next few months.  Please look for announcements in the coming weeks and months as we resume our in-person helplines, Farmers Markets and Master Gardener tabling at community events. We will send out notification when these events are open for registration.

Master Gardener Helplines to Open

Three people in office, with thumbs up

We are happy to announce we are opening the metro area Master Gardener office helplines in the coming months.  The resumption will be staggered across the 3 counties, as we train volunteers to use our new online helpline system.

The online helpline system is the same system we have been using to serve the public remotely the past two years.

An orientation on the new helpline system is a prerequisite to volunteering in the office. Look for upcoming announcements to register for an orientation.

Update Your CERVIS Profile

Sign-up for upcoming volunteer shifts at Farmers Markets, Helplines, and special volunteer opportunities will be on CERVIS.  In order to be ready to sign-up, when the time comes, please visit CERVIS and update your profile, including your mailing address and phone numbers.

Welcome 2022 Cohort

We would like to extend a warm welcome to our 140 trainees from Clackamas, Multnomah and Washington counties.

We are excited to have you join our program of committed garden educators. Your online training is winding down, and soon you will be out in the community actively practicing and sharing your newfound knowledge

Possibilities will abound with a wide range of volunteer opportunities. We hope you will dig in, have fun, and share your passion for gardening with fellow MGs and the gardening public.  This is an opportunity to further your garden education and  gain confidence in teaching others how to sustainably and successfully garden.

A big shout out of thanks to all the Master Gardener associations and volunteers who have developed and are leading the instruction of hands-on workshops to the trainees. You have created a stellar line-up of educational offerings to support trainees in their journey to serve the community as garden educators!

Perennial Master Gardeners, as you start volunteering in-person this spring and summer, be sure to extend a warm welcome to both our 2020 and 2022 Cohort members as you meet them at events.
