Tis the Season for Master Gardener Annual Reporting

Autumn marks the season for annual reporting of volunteer service and continuing education hours for metro area OSU Master Gardeners. All current, certified, metro area Master Gardener volunteers received an email from Marcia McIntyre in September with a survey link to report their hours.

Note: for 2022 the 20-hour volunteer service requirement was waived.  10-hours of designated continuing education hours are required for Perennial Master Gardeners in 2022.

2020 and 2022 cohort members have an additional year to complete their Master Gardener training requirement of 40 hours of volunteer service but please take the time to respond to the survey.

A big shout out of thanks to all who have submitted your hours by answering the survey and uploading your log sheets.  We love seeing where you are serving in the community.

For those who have yet to respond to the survey, please respond, so that you will be kept on the active, certified Master Gardener role. We have extended the deadline to October 31, 2022

In addition to this survey, we sent, via email, the annual Conditions of Volunteer Service document and a Standards of Youth Safety document.  To make the process quick and easy, the documents were sent via DocuSign, from OSU Extension office specialist Catalina Santamaria.

Please answer the survey and return your signed Conditions of Volunteer Service form no later than Sunday, October 31, 2022.


Time remains to fulfill continuing education requirement

Annually 10-hours of designated continuing education hours are required for Perennial Master Gardeners to maintain certified status.  For 2022, we have extended the deadline for fulfilling and reporting the required 10-hours of continuing education until October 31, 2022.

There is a great variety of designated continuing education opportunities to enrich and support you in your role as a garden educator.  Opportunities include webinar recordings that can be accessed from the comfort of your home!  So put your favorite streaming service aside and start binge watching some great designated, garden education presentations.

The following opportunities can be counted as ‘Continuing Garden Education’ hours for Perennial Master Gardeners and can serve as educational enrichment for 2020/2022 cohort trainees.

We are excited to share that Sherry Sheng has been recognized as the 2022 OSU Behind-the-Scenes Master Gardener of the Year!  Sherry’s deep commitment to providing quality education to all those interested in gardening is evident in her thousands of hours of volunteer service (logging over 7,500 hours the past 17 years).  Sherry has led the Clackamas County Master Gardener Association’s, highly successful, 10-Minute University Program for 12 years. With the onset of the pandemic, Sherry realized a deep public need and led the launch of a noontime chat webinar series that engaged over 7,000 viewers from around the world.  Sherry is a generous supporter and champion of the OSU Master Gardener Program. We are extremely grateful to Sherry for her many years of generous leadership and service!  We extend hearty congratulations to Sherry for this well-deserved recognition!

As an OSU Master Gardener volunteer do you receive questions about damp or soggy landscaped areas? Do you have inquiries about resources for how to convert a lawn space with native plantings?

The Stormwater Stars program focus is to help provide tools and build confidence for people to work on their own landscape spaces to improve watershed health, enhance habitat and reduce the need for harmful lawn and garden chemicals. The basic practices we work with include lawn replacement, depaving, amending soil, porous pathways, contained planters and planting native plants. We host hands on installation workshops in the Fall and Spring to demonstrate these practices on private residential properties, at businesses, or community spaces. We also provide free site visits to homeowners and property representatives to help provide guidance for landscape improvements for watershed health.

Sign up for our Workshops:

People planting plants in open garden bed.

Sign-ups for our free workshops happen through the website. At the workshops we spend a little time introducing what we will be doing that day, and the bulk of the time is spent with our gloves on making the improvements to the site. Every workshop is different and throughout the season we do our best to provide opportunities to learn a variety of different landscaping practices on different size projects.

Sign-ups for our Fall Workshops have begun on our website:

https://www.stormwaterstars.org/events

Currently we have one workshop scheduled on November 13 from 1:00 pm – 3 pm in the Crestwood neighborhood of SW Portland.  We will be reviewing how to remove grass and working to replace it with a beautiful landscape using Willamette Valley Native Plants.

What about hosting?

Garden bed with plants, including blooming lupine, plus a mailbox with signs posted on the side: Stormwater Stars, Certified Backyard Habitat, and Pesticide Free Zone.

We are still looking for Fall Workshop locations as well as locations for the Spring and beyond.

Our workshops are open to everyone however workshops are located within the West Multnomah Soil and Water Conservation District service area. The program was started in 2014 and initially focused on locations in SW Portland. We have since expanded the area that we serve and are actively looking to hold more workshops in NW Multnomah County.

For those interested in hosting a workshop, we will come look at spaces in their yard that might be a good fit and what practices could be demonstrated. Our workshop areas are typically about 600 square feet in area, but can vary depending on what the site needs. Workshop projects must be visible to the public, typically in front or side yards. Together we will decide if your space would be a good location to bring in volunteers where we can create and learn together. If your site is selected for a workshop we will work together to make a plan. Each site varies in terms of what is needed, and we provide assistance with design, plant selection, compost and native plants.

Interested in learning more?

Please contact the Stormwater Programs Specialist Rachel Dvorsky with questions or to set up a site visit at hello@stormwaterstars.org. You can also find more information about our program, practices, as well as past projects on our website at www.stormwaterstars.org

We look forward to seeing you at a future workshop!

Stormwater Stars is a program delivered by Neighbors West Northwest and the Westside Watershed Resource Center, in partnership with and funded by generous contributions from West Multnomah Soil & Water Conservation District and City of Portland Bureau of Environmental Services.

Pacific Northwest Handbooks Online

Black and yellow butterfly, with flowers in the background.

The go-to resource for Master Gardeners diagnosing plant and pest problems are the Pacific Northwest Handbooks, often referred to as PNW’s.  Starting this year Oregon State University is only offering the PNWs online with no print option.  Therefore if you are tabling at a Famers Market or other community tabling event, you will not see those familiar tomes in the clinic supplies.

While at a remote MG clinic table, like a Farmers Market, you can access the PNWs via your smartphone or if you prefer not using your phone to look up information to assist a client, please refer the client to our Master Gardener Helpline.  Each clinic box has a yellow tear-off pad with contact information for the Helpline.

Pacific Northwest Disease Management Handbook

Remember, do not give any chemical recommendations without first referring to the current issue of the PNWs.

If you would like to familiarize yourself with the online version of the PNWs.  Here are two great video tutorials.

Here Comes the Sun! Take Precautions!

Yellow flowers, with blue skies and clouds in the background.
Sunshine” by rkramer62 is licensed under CC BY 2.0

Here comes the sun, and with it the potential for searing temperatures and we want to make sure that you take care of yourself at Master Gardener volunteer events.

When taking part in metro area OSU Master Gardener or supporting Master Gardener association outdoor volunteer service activities, please take steps to protect yourself from the extreme heat. 

Heat illness is a serious medical condition resulting from the body’s inability to cope with a particular heat load and can progress quickly from mild symptoms to a serious and life-threatening illness.

Please be sure to take regular breaks in the shade if your volunteer shift is in the sun.

Bring enough cool water so that you have access to 32 ounces per hour during your shift.

Learn how to recognize signs of heat exhaustion and heat stroke. 

Be aware of how your body is coping with heat. If you develop any heat-related illness, excuse yourself from the shift and take care of yourself. Ask for help from another person if needed.

Please keep an eye on your fellow volunteers and watch for any signs of heat exhaustion or heat stroke and take the appropriate action to assist them if you recognize symptoms.

Please contact Weston Miller (metro area OSU MG program manager) to report any heat-related illness.

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.

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.

A Note from Margaret:  Please considering joining us for our twice-monthly Zoom meetings; the first and third Mondays, from 1-3 pm!

Tri-county Master Gardener STUDY GROUP

  • The MG Study Group is a self-organizing collection of seasoned and new MGs (and everything in between) who love to learn!
  • We serve all three counties via our Zoom meetings: Clackamas, Multnomah & Washington.
  • We meet twice a month to develop our skills in identifying and understanding insects, spiders, and plant diseases and disorders, etc.
  • Meetings are based on group participation.
  • All interested OSU MGs and interns are welcome. (We are not open to the general public)
  • Attendance is not required; join us when we can!
  • On first Mondays we generally conduct an informal show-and-tell session, where MGs share samples of insects, spiders, plants for identification and/or diagnosis by the group. This is a great deal of fun and no advance work is required except for collecting a sample. (If you don’t have a sample-no problem! Join us anyway).
  • The third Monday is a more formal session based on a Study Guide you receive about a week ahead.  Study Guides are developed voluntarily by attendees about subjects that are of interest to them and to share with the group.  Upcoming Study Guide session topics for 2022Bullies in the Garden-Invasive and Overly Enthusiastic Plants, Summer Heat Woes, Downy Mildew, Pruning, Blackberries, Best Garden Practices, and a Group Diagnostic practice.

Great information about dogs and lawns: Dog Spots! No, not dalmatians but dead spots in the lawn. With the low rainfall and lack of irrigation pet owners may be seeing dog injury to their lawns. Urine damage can be mistaken for symptoms of several patch-type diseases. Samples of the dead grass placed in a plastic bag will release ammonia, which can be detected by smell. Other chemical injury such as fertilizer spills or salt spills can cause similar symptoms but do not release an ammonia odor. Female dogs are usually more damaging as they urinate on the ground, in the same spot and tend to empty their bladders more completely than males. And FYI, yes, this is research-based info!” (PNW Plant Disease Management on Facebook) More information: https://bit.ly/3GZbTPq
