The scientific reasons you should resolve to start gardening in 2023.  “Funded by the American Cancer Society, the first-ever, randomized, controlled trial of community gardening found that those who started gardening ate more fiber and got more physical activity—two known ways to reduce risk of cancer and chronic diseases. They also saw their levels of stress and anxiety significantly decrease.” (Lisa Marshall,

REVISED PUBLICATION: Gardening with Oregon Native Plants West of the Cascades.  Growing a garden in western Oregon is easier when you include native plants. That’s because native plants are adapted to our wet winters and dry summers. Native plants also provide benefits to native pollinators and other wildlife. Learn where to find native plants for your garden, how to care for them and which plants are best for pots and small gardens. This publication also includes an illustrated list of Pacific Northwest native plants that are easy to establish and grow.” (Linda McMahan, Heather Stoven, Erika Szonntag, OSU)

REVISED PUBLICATION: Northern Giant Hornet: A Potential Threat to Honeybee Colonies in Oregon.  “The northern giant hornet was detected in British Columbia and Washington in 2019. This publication outlines the identification, life cycle, and predatory habits of the northern giant hornet (Vespa mandarinia) for beekeepers. It also provides recommendations for reporting a suspected sighting in the Pacific Northwest (Ellen Topitzhofer, et al, OSU)

REVISED PUBLICATION: Growing Your OWN.  “Growing Your Own is now available as a bilingual publication in Spanish and English! It provides basic advice on a wide range of gardening topics, including composting, container gardens, fall/winter gardens, fertilizing, insect pests, plant diseases, planting guidelines, raised beds, site selection, slugs, soil improvement, tilling, warm-season crops, watering, and weeds. Includes regional tips for various parts of Oregon.” (Gail Langellotto, OSU)

Vaccine protects honeybees. The U.S. Department of Agriculture has approved a conditional license for a vaccine that protects honeybees against American Foulbrood disease. (Simrin Singh,

Companion plants, they are not what you think!  Companion plants! Great, what a good idea. When you first hear the term and think about the concept it sounds great, but there is a lot to not to like about it. The term “companion plants” implies that these plants are partners and they “enjoy” each other’s company.  The term is an anthropomorphism or overlaying human qualities on non-human organisms.  A more appropriate term may be plant associates or plant associations, a term taken from plant ecology which more basis for its use.” (Jim Downer,

Goodbye to 2022 and hello, 2023!  A review of “…the weather and climate of the past year, both the average conditions and some of the extremes we saw.” (Pam Knox,

Pest Profile: Spotted Lanternfly. Be on the lookout! The Spotted Lanternfly (SLF), Lycorma delicatula, is a 1-inch long planthopper native to China, and has since spread to Japan, South Korea, and the United States.” (Abi Saeed,

So you think you want a home greenhouse, do you?  “… home greenhouses have been a “thing” for a long, long while – from well-to-do folks with conservatories on their estates to the more common and basic home greenhouse in the last few decades.  But shifting interests, and more/cheaper options have made home greenhouses more accessible to the masses.” (John Porter,

Sunflowers Linked to Reduced Varroa Mite Infestations in Honeybees.  “A new study indicates a benefit to honeybees of local sunflower cropland.  Even low levels of sunflower acreage nearby correlate with reduced Varroa mite infestation in managed colonies, researchers found, and supplemental sunflower pollen helps ward off the mites as well.” (Paige Embry,

HIRING AN ARBORIST– MGs sometimes can’t identify a tree problem via a phone call or email.  Our diagnostic skills are limited in that we can’t go to the site to see the tree in person.  Photos and the plant’s history can provide a wealth of information, but sometimes seeing the tree on site may be necessary to give a correct diagnosis.  In such cases, clients should be advised to hire a Certified Arborist.

Here are a few suggestions on hiring a ‘Certified Arborist’:

  • As representatives of OSU, Master Gardeners don’t endorse a specific business or
  • Many commercial companies employ Certified Arborists–This means that they have passed tests recommended for their industry and have taken part in continuing education to further their knowledge.
  • Suggest client search on the internet, ‘Tree’ or ‘Trees’ or ‘Tree Service’ in their area.
  • Then look for statement or logo stating Certified Arborist.
  • Some companies may charge a fee for an on-site inspection.
  • Check to see if licensed and bonded.
  • Encourage client to get at least 3 estimates before selecting a company to do any work. 
  • The International Society of Arboriculture certifies arborists and has list of their certified arborists (more info below.)

Clients can be referred to ISA (International Society of Arboriculture) for information on Certified Arborists: “ISA exists so that professionals, allied professionals, public officials, and consumers worldwide recognize the economic, environmental, and societal benefits and values of trees and their care at a cost that demonstrates the wise stewardship of resources.”   Go to: (click on the link ‘Find an Arborist’). 

This takes you to the site: ‘Trees Are Good’ ( ). “The International Society of Arboriculture manages ‘’ …an educational website that provides the public with quality tree care information…helps increase awareness of the benefits of trees and provides homeowners and other tree owners with access to resources to help sustain trees in an urban environment. Examples of a few resources you’ll find on include:

Screen shot of title page of webinar "Native Plants for Gardens and Pollinators"

In November, we enjoyed the reprise of our Fall Recertification with 4 webinars focusing on information to support you in your role as garden educators.  Many thanks to our presenters, Cecile Evans, Dr. Gail Langellotto, OSU Master Gardener Program Manager, Alex Gorman, OSU Forestry and our very own Weston Miller, who all provided thoughtful, informative presentations.

If you were unable to attend, you can view recordings of three of the presentations here.

Stellar Hands-on Workshops

To enrich our 2022 OSU Extension Service Master Gardener training, we ventured into the garden and offered 36 hands-on workshops for Master Gardener trainees. Nineteen garden-focused topics were presented that ranged from ‘Insect Identification’ to ‘Gardening for Wildlife’. 

The workshops were made possible all thanks to a team of experienced Master Gardener volunteers who developed and delivered the engaging hands-on instruction. 388 class slots were filled. Participants shared their appreciation for the hands-on opportunity, “The instructors were top-notch”, “I loved being in the garden, seeing plant pests and diseases up-close”.

A special shout-out of gratitude to Susan Albright, Sherry Sheng, and Corinne Thomas-Kersting for their time and efforts coordinating and guiding the development of the Hands-on Workshop curriculum in their county’s.

These science-based workshops support our Master Gardener training cohort members in serving as effective community educators.

Hearty thanks to these metro area OSU Master Gardeners who volunteered their time to plan and deliver 36 fantastic hands-on learning opportunities…

Youth Garden Education Volunteer Opportunity

Do you enjoy teaching garden-focused classes to youth? Do you have interest in going into school classrooms and/or school gardens to teach, fun, engaging garden concepts? We are looking for a team of Master Gardener volunteers interested in school outreach.

Every year we receive multiple requests for Master Gardeners to teach at area schools and with these requests we have realized the need to have prepared ‘garden education kits’ which Master Gardener volunteers can easily take into classrooms and school gardens to deliver focused and engaging garden education curriculum.

In anticipation of school requests in the coming year, we are seeking Master Gardeners interested in participating in teaching youth. Master Gardeners would teach alongside a fellow MG volunteer. In advance of signing up to teach a specific class there will be an orientation to familiarize all volunteers with the ‘garden kit’ curriculum, along with completion of a criminal history check which is required by OSU for volunteers teaching youth.

A small yet mighty committee of metro area Master Gardeners have developed seven ‘garden education kits’ to launch this project. 

The topics include:

  • Calling All Pollinators
  • Invertebrates/Vertebrates In the Garden
  • Some Insects are Heroes
  • What Makes an Insect an Insect
  • Wonderful Worms

Each kit includes learning objectives and an outline for delivering the class, including activities, and supplies. Volunteer time designated as ‘Program’ hours.

If you are interested in serving as a garden educator, alongside another metro area Master Gardener at area schools, please contact Marcia McIntyre.

Sincere thanks to the Education Outreach committee for developing these engaging and valuable lesson plans: Cheryl Borden, Cheryl Brock, Jane Collier, Larina Hoffbeck, Jack Lazareck, Corinne Thomas-Kersting, and Hope Preston.

New! Valuable Pest Management Resource

After several years of extensive planning, collaboration, and fine-tuned development, a user-friendly, science-based, online resource to help urban and rural communities to solve pest problems is now a reality!  In partnership with OSU and Oregon stakeholders, Solve Pest Problems launched this fall with 50+ web pages focused on high-priority pests, pesticide safety, and pesticide risk reduction methods.

The project led by the vision of our very own metro area OSU Master Gardener Program manager, Weston Miller, prioritizes low-risk pest management approaches. The content focuses on topics to help Oregonians and anyone in the Pacific Northwest solve common pest problems. 

Solve Pest Problems has hundreds of high-quality color photos to correctly identify pests, along with practical prevention and control methods. With it’s science-based solutions it will serve as an invaluable resource for Master Gardeners guiding and supporting Oregon gardeners in successful and sustainable gardening practices.

Be sure to explore the site to discover more about this useful resource. If you missed Weston’s Fall Recertification presentation highlighting details about Solve Pest Problems, you can view the recording.

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:

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 You can also find more information about our program, practices, as well as past projects on our website at

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.

Currently Master Gardeners are tabling at the Beaverton, Gresham, Hillsdale, Molalla, People’s Co-Op, and Oregon City farmers markets. Sign up for these ‘Program’ volunteer service opportunities and more on CERVIS.

‘Partner’ Volunteer Service Opportunities

Growing Gardens
Home Gardens Program Garden Mentors
The Growing Gardens Home Gardens Program helps BIPOC and low-income English and Spanish-speaking families learn to grow fresh organic produce at home. Families participate in Growing Garden’s program for 3 years and are provided with raised garden beds, tools, seeds, plant starts, classes, and mentoring. Master Gardeners can serve as Garden Mentors to the Home Garden’s families by providing sustainable gardening guidance and one-on-one support to beginning gardeners, including visiting gardeners for summer consultations. BIPOC volunteers and Bilingual Spanish speakers are needed. This is a ‘Partner’ volunteer activity.  If interested in volunteering contact: Antonio Rodriguez  503-284-8420

International Rose Test Garden Tours
Master Gardeners conduct 45-minute tours of the garden.  Master Gardeners will educate the public about best gardening practices, specifically as they relate to roses. This may include IPM, site selection, hardiness zones, winter care, and research based methods for encouraging beautiful gardens. Some history of the International Rose Test Garden and Portland’s designation as the City of Roses will be incorporated into the tour.  Scripts and training are available for all guides. This is a ‘Partner’ volunteer activity. If interested contact Harriet Ottaviano via

NOTE: Rose pruning, weeding, maintenance does not count as volunteer service hours.

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.

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!

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.

And/or search online:

1. Add “site:edu” to the search word or phrase, but omit the quotes.

2. If you search for sunburn, try “sunburn +plants site:edu” (omit the quote marks).  (Doing so will help limit the number of references to sunburned people!)
