It was a lovely afternoon—such an afternoon as only September can produce when summer has stolen back for one more day of dream and glamour.

L.M. Montgomery




The waning days of summer usually involve Master Gardeners compiling all their volunteer service hours for submission. Yet, we realize that the ongoing pandemic has brought an array of challenges to so many of our volunteers and it has also severely limited our volunteer service opportunities. Therefore, we have waived all annual volunteer service and continuing education hour requirements for Perennial Master Gardeners for 2021. We have also extended the time period for 2020 Master Gardener trainees to complete their training volunteer service requirement, until September 30, 2022.

Yet it is still important to document all hours that metro Master Gardeners were able to serve since October 1, of 2020, and the many hours of continuing education that you logged via our online offerings. We want to celebrate and share your contributions with OSU. We will be sending you a brief survey in the next week for you to submit your volunteer service and continuing education hours. You do not need to submit a log sheet. Simply answer the survey questions and click submit. We hope you will take a few minutes to complete the survey and show the contributions of service made during such challenging times.

Metro-area Master Gardeners Recognized and Thanked for Service

Each year the three metro area supporting county associations nominate and designate members for special recognition, either through an Oregon Master Gardener Association (OMGA) nomination or by heralding their praise and appreciation.

This year is no different and we would like to extend our hearty congratulations and thanks to the following individuals who are being recognized for their extensive contributions as OSU Master Gardeners!  Congrats and utmost gratitude to all!

Two Metro Area Master Gardeners Honored with State Awards!

We are thrilled to share the news that two metro area Master Gardeners were recently designated as the Statewide awardees!  Susan Albright as Statewide Master Gardener of the Year and Sue Ryburn as Statewide Behind-the-Scenes Master Gardener of the Year.  Susan and Sue’s dedicated service has greatly benefited the Washington County Master Gardener Association (WCMGA), the metro area and statewide OSU MG program, and the community as a whole.  We are thrilled they have been honored and are grateful for their tremendous contributions to the Master Gardener program!


2021 Statewide Master Gardener of the Year

Susan Albright, Washington County: Over the past decade, Susan Albright’s dedication and impact for gardeners in Washington County has been profound. She’s held so many leadership and co-leadership positions they’re too many to list, and her background as an educator has been brought to the forefront of her work as a master gardener volunteer. She’s designed and planted areas of demonstration gardens, provided leadership in establishing educational outreach goals, and developed educational materials for adults and children. She has presented at the statewide level, and is an active citizen scientist, combining forces with Xerces and Oregon Bee Atlas. She has led the Washington County Master Gardener Association through changes and adjustments, all with incredible communication and teamwork. – LeAnn Locher

2021 Statewide Behind-the-Scenes Master Gardener of the Year

Sue Ryburn, Washington County: Sue Ryburn may be a tremendous leader, but she’s also a significant doer, working behind the scenes on multiple projects at a time. Whether it’s securing tens of thousands of dollars in grants, establishing multiple education gardens, or developing Washington County’s “In the Garden Series” as a deliverable to gardeners at home during COVID-19, she consistently looks beyond boundaries of the association to establish community partnerships and work collaboratively with program leadership. This commitment to collaboration can be seen in her formation of the Community Collaborators group, made up of organizations with like-minded missions to that of the Washington County Master Gardeners Association. This network and support are invaluable, innovative and exciting work, true to the spirit of everything she takes on. – LeAnn Locher


Clackamas County Master Gardener Association

Special Recognition for Three Dedicated Clackamas County Master Gardener Association Members
The Clackamas County Master Gardener Association (CCMGA) is giving special thanks and recognition to three members who have worked above and beyond for their very successful programs during this pandemic year.  CCMGA President John Wilbur writes…”We would like to recognize and thank, Nancy Muir and Eve Freeman for Grow an Extra Row (GAER) and Sherry Sheng for the webinars. Both programs were highly successful and made an important impact on the community during these difficult times.  We also acknowledge the support and participation of the additional chapter members who assisted in these programs.  Thank you all for your efforts.”


Multnomah County Master Gardener Association

Multnomah Co. Master Gardener Association – Master Gardener of the Year
As Multnomah County Master Gardener Demonstration Garden Director, Linda Goldser has helped guide both the Master Gardeners who volunteer in the garden, but also the garden’s future.

Elaine O’Keefe brings significant experience and insight into organizational structure and serves as representative to the OMGA, and the Diversity, Equity and Inclusion Committee.  – LeAnn Locher

During the pandemic, Cynthia Chase and her communication skills kept the board moving forward. Her personal fundraising skills have helped raise money for the demonstration garden and she serves as the chapter’s Facebook editor.  –LeAnn Locher

Multnomah Master Gardener Association – Special Projects Award

Bob Shaw was given a Special Projects Award for his work in the Demonstration Garden.  Specifically, for his work in the North Hedgerow area of the garden where he documented the work.

Washington County Master Gardener Association

Washington Co. Master Gardener Association – Master Gardener of the Year
Karen Graham
has led the Washington County Master Gardener Association through times like no other, with calm and resolve. With the many challenges that arose through the past several months the association needed to make quick and nimble adjustments. Karen adeptly handled each challenge. She quickly adapted and learned how to keep communication lines open with association membership and members of the public, taking the WCMGA’s Speaker Series and meetings online.  The WCMGA has greatly benefited from Karen’s positive, calm, and encouraging leadership.

Washington Co. Master Gardener Association – Behind-the-Scenes Master Gardener of the Year
In a mere three years, Fran Beebe has wasted no time making significant contributions as an OSU Master Gardener and Washington County Master Gardener Association member.  Fran has been instrumental with the WCMGA’s GardenFest fundraiser, potting 100+ houseplants, creating nearly as many terrariums and 30 hanging Kokedams for the sale and was a key contributor to the Propagation Team producing nearly 2000 vegetables and flowering plants. When Gardenfest 2020 was cancelled, Fran helped maintain the propagated plant stock, and, when it was mandated the greenhouses be closed, helped with distribution, donation and foster care for the plants.  Fran serves on the Speakers Committee and is a dedicated OSU Master Gardener Helpline volunteer.


Growing Oregon Gardeners: Level Up SeriesAutumn 2021

Join the Growing Oregon Gardeners: Level Up Series on Tuesday, September 14, 3PM, as Dr. Gail Langellotto, presents, Gardening with Native Plants for Pollinators.

Native plant gardening has been ranked as one of the top three landscape and garden trends over the past few years, in part because of the benefits that it offers to pollinators. However, native plants are not widely planted by home gardeners, and only limited selections can be found at many retail nurseries. This talk will share research conducted by the OSU Garden Ecology Lab for the past four years, and will address questions such as:

  • Which Willamette Valley native plants are most attractive to pollinators?
  • Why aren’t native plants more broadly available for purchase?
  • What native plants are most attractive (according to Oregon gardeners), and which native plant traits gave gardeners concern?
  • Are native cultivars a good approach to some of the problems associated with the production and sale of native plants?
  • Do pollinators visit native cultivars as much as they do native plants?

Finally, we will end with our recommendations for native plants that western Oregon gardeners should plant, if they want to support Oregon’s pollinators.

Register here.

Coming up in October and November…

Adapting Your Garden and Landscape for Climate Change, Tuesday, October 13, 3PM
Join in as Weston Miller shares strategies to adapt gardens and landscapes to the new extreme weather conditions we are now experiencing in the Pacific Northwest.

Healthy Soils for Healthy People, Tuesday, November 9, 3PM
Research has suggested that healthy soils can benefit human health, via transfer of beneficial microbes from the soil to the skin. Dr. Gail Langellotto will provide an overview of what is known as the ‘hygiene hypothesis’, and how this relates to healthy garden soils.

Register for the upcoming webinars or view recordings of past webinars here.


The Culture of Gardening

The OSU Master Gardener Program’s Diversity Equity and Inclusion Taskforce has launched a new storytelling initiative called ‘The Culture of Gardening’. This initiative explores and shares the voices of gardeners growing plants to connect with their heritage, culture, and identity. While it’s a project of the OSU Extension Master Gardener program, the stories transcend us, weaving through our communities and identities and include farming, self care, family celebration, recipes, tools, and more.

Tyler and his dog

Gardens and gardening connect us in many ways: to where we’ve been and to who we are. To grow a plant that is inherent to our identity is a joyful and self-affirming art, whether it’s a food to eat or a flower to use in tradition and celebration. Stories are being collected of people all around us, past and present, who do just that: the voices of gardeners growing plants to connect with their heritage, culture and identity.

Explore these inspiring stories and celebrate the different ways we all come to the garden. Meet Ann, Athen, Charlie, Farah, and Tyler. Check back as more gardeners generously share their voices and their connection to their heritage, culture, and identity through gardening.

If you have a story you’d like to share, or know of a gardener who connects with their culture and identity through gardening (they don’t have to be a Master Gardener!, but they should have a connection to Oregon), please contact: LeAnn Locher

Rosy news…

As we near the start of summer there is promising news! COVID risk levels are lowering in the metro counties and we are receiving encouraging OSU updates with guidelines for resuming some of our Master Gardener activities. We will gradually resume activities as the guidelines and our capacity allows, in the coming months. Watch for updates via email and this newsletter, as we are able to open our program activities.

Help with MG Community Needs Assessment

Help the OSU Master Gardener program in learning the needs of our community.  The program has launched a survey to guide the work of the MG program and to learn the types of gardening information Oregonians want/need to support them in successfully growing plants.  The goal is to hear from 5,000 Oregonians across the state, especially those not currently involved in the Master Gardener Program.

You can help to distribute the survey and earn volunteer hours by sharing the text and accompanying images below, with your own networks! 

Share the survey with 3 of your networks and earn 30 minutes of volunteer service. If you have additional networks on which to spread the word, please count an additional 10 minutes of volunteer service for each share/post.  Keep note of your volunteer time sharing the survey and include those minutes/hours when you report your volunteer service in the fall.

Please share on local metro area networks or those limited to Oregon. Share the survey with any communities who might have an interest in gardening. Here are some suggested networks in which to share the survey…

  • Share to your personal and/or professional social media accounts: Facebook, Twitter, Instagram, LinkedIn, Others
  • If you use ‘NextDoor.com’, consider inviting your neighbors to participate in the survey
  • If you are part of your area PTA/PTO, ask the organization if you can share the survey link with school parents
  • If you are part of a church, club, fraternal organization, or other social group that is not generally associated with gardening, but you know that the members are interested in gardening, please consider sharing the survey with them
  • If you volunteer with other organizations that serve clients that may be interested in gardening, please ask them if they can share the survey link with their clients
  • Gardening Groups and Clubs: If you are a member of a gardening group or club (online, or in person), please consider sharing with those groups. Before posting on another group’s page or website, make sure that you have permission to post the invitation and survey link.
  • Facebook gardening groups (focus on those that are local or limited to Oregon, rather than out of state or national groups)
  • Email listserv of gardening groups or clubs (once again, focusing on local groups or limited to Oregon)

Below is the text and graphic promoting the survey, in both English and Spanish.

Inquiries from Ask Extension

Jean R. Natter, OSU Master Gardener

Houdini fly in Multnomah County? (Multnomah County; 2021-04)

Q: We noticed these flies in our mason bee tubes. After some googling we think it might be a Houdini fly. Is this something that needs to be reported? Are there steps we need to take to help the bees?

Houdini fly.
The Houdini Fly, Cacoxenus indagator, was recently identified as an invasive pest in Oregon; it is a kleptoparasite from Europe which lays its eggs on the pollen cake meant for a Mason Bee, thereby starving the bee. (Client image; 2021-04)

A: Thank you for the excellent images of the Houdini Fly, Cacoxenus indagator, recently identified as a serious, exotic insect pest of Mason Bees.

Here’s a pest alert about the Houdini Fly with good images, plus suggestions for people who keep mason bees. See “Houdini Fly Found in Washington” – https://agr.wa.gov/departments/insects-pests-and-weeds/insects/apiary-pollinators/pollinator-health/houdini-fly

This website provides additional details about protecting your Mason Bees: https://crownbees.com/houdinifly.

Because the flies move slowly, you’ll be able to collect several samples to submit for ID. Refrigerate them in a small covered container until submitted. (Feel free to crush any extra flies you may discover later.) 

I suggest you report the flies to the Invasive Species Hotline; call 1-888-468-2337 or use their online form at https://oregoninvasiveshotline.org/reports/create.

Overrun by little moths! (Lane County; 2021-05)

Q: The east-facing side of my Coburg, OR, home has hundreds of little moth-like bugs lighted on it. They started to appear in early April, when the weather started warming up. Can you tell me what they are, and how I can control their population?

A: The small insects are called Drain Flies, a Psychoda species. Other common names for them are Moth Flies and Filter Flies.

Drain Flies are most commonly found indoors near moist areas, such as sinks, wet-mops that have been wet for several days, or in damp basements. These flies are poor fliers and are often found near their source.

Potential sources outdoors include a nearby area that remains moist for an extended period. Places to investigate as a source include roof gutters clogged with debris, at the base of downspouts, a wet spot near a leaking spigot, moist compost, and/or dirty garbage cans.

Drain flies are considered to be nuisance pests because they don’t cause damage to people, their pets or belongings. The remedy is to locate and eliminate their source. No pesticides needed. A wet-dry shop-vac could help decrease the number of the adults but will do little as long as the moist breeding site remains.

White Egg Like Spots (Clackamas County; 2021-05)

Q: What are these white egg-like spots on my bush?

Azalea Bark Scale on branch of shrub.
Azalea Bark Scale are small white, sedentary, sucking pests which slowly drain the vitality of several shrubs, especially Azalea, Pieris (Andromeda), and Rhododendron. (Client image; 2021-05)

A: Azalea Bark Scale are small sucking insects which can cause their most common victims — Azalea, Pieris (Andromeda), and Rhododendron — to slowly decline over an extended period of time. (Certain other shrubs may also be affected, but far less often.)

You can physically attack those small beasts by rubbing them off with a toothbrush.

Then, because you’re very likely to miss the small, newly hatched larvae (youngsters), follow-up with a commercial Insecticidal Soap Spray, diluted according to label directions. Coat all surfaces of the stems and branches thoroughly, front and back, top and bottom. Then repeat the spray, as needed, through the following months.

Woolly aphids on Old Apple Tree (Multnomah County; 2021-05)

Q: Our old apple tree has wooly aphids, how can this be treated!

A: Woolly apple aphids, Eriosoma lanigerum, are impossible for home gardeners to eradicate. The reason? The main colony of woolly apple aphids are on the tree’s roots whereas only some move to the top growth every spring. The result of an infestation is a gradual decline in tree vigor. In spite of that, fruit yields are often large enough for a family’s use.

Our official Insect Management Handbook says “This aphid is considered a minor pest in the PNW. If colonies are found on trees, they can be physically removed. Many Geneva and Malling-Merton rootstocks are resistant.”

You can limit the damage somewhat by spraying commercial insecticidal soap, prepared according to label directions, directly on the woolly aphids you find on the bark, then repeat as need through the growing season. Other pesticides that might be considered are rated as “highly toxic to bees.”

No pesticides are available for soil treatment.

In commercial apple orchards, woolly apple aphids would be avoided by not planting susceptible kinds of apples. You might consider planting a new apple with one of the resistant rootstocks mentioned above.

2nd Q: We’ve just tried some Safer Insecticidal soap and will reapply again tomorrow.
Last year the tree produced lots of apples, this year we see very few coming. Will these aphids harm surrounding plants?

2nd A: Woolly apple aphids are specific to apple trees. They won’t damage other plants.

It’s unlikely you’ll need to use insecticidal soap daily. Limit its use to when you see new aphids, then spray only the fresh white specks.

This year’s small crop may be a normal event because apple trees tend to “alternate bear.” That is, after they produce a huge crop, the following year they’ll produce a small crop.

But, there’s a simple trick to even out production one year to the next. It’s called thinning.

To thin, when the fruit is thumbnail-sized, remove the excess to a reasonable number. In general, the goal is to keep only one fruit per cluster. However, if what remains may be too heavy a load for the branch at harvest, remove even more of the as yet undeveloped fruits.

The result of thinning? Even though you’ll have fewer apples at harvest, they will be large for their kind and high quality.

ID what ate my dahlia? (Multnomah County; 2021-05)

My dahlia was about 8 inches tall and had a quick death, did some digging and found these little white worms around the stem looks like they ate it. What are they? What’s the best way to get rid of them?

A: Thank you for attaching the images. The 1st image (white larvae and wet soil) and the 3rd (rotted stem) are the most telling.

It’s very likely the stem rotted from excessively wet soil, then the larvae came in to clean up the debris. It’s also likely that the tuber is also rotted.

After dahlias begin growing in the spring, they do well with moderately moist soil.

Spring greetings Master Gardeners!  Although our in-person volunteer activities remain on hold, there is a plethora of informative and inspiring virtual presentations being offered to Master Gardeners in the following weeks and months.  We encourage all Master Gardeners to take advantage of these valuable continuing education opportunities.

The Culture of Gardening Series

The OSU Master Gardener Program’s ‘Culture of Gardening’ Series kicks off with a special presentation with Abra Lee, “The Work is in Our Hands”, on Tuesday, May 18, 12noon.

Through determination, enthusiasm, and willpower Black women overcame ugliness in America to cultivate beauty in the landscape. This is a discussion of how their self-expression and activism through gardening led to a lasting legacy of community pride throughout generations. 

Abra Lee is a national speaker, writer, and owner of Conquer the Soil,a platform that combines Black garden history and current events to raise awareness of horticulture. She has spent a whole lotta time in the dirt as a municipal arborist, extension agent, airport landscape manager, and more. Lee is a graduate of Auburn University and alumna of the Longwood Gardens Society of Fellows, a global network of public horticulture professionals. 

This presentation is free and open to all OSU Master Gardeners and the public.  Register in advance here: https://beav.es/JCF

Thank you to all who participated in the state-wide ‘Elevated Skills’ Master Gardener training earlier in the year.  We have received lots of positive feedback from MGs who appreciated the opportunity to focus on skills that can be used in their roles as a garden educator; whether it was learning more about ‘Community Science’, how to ‘Superpower Your Education Garden’, ‘Recipes for a Collaborative Community’, ‘Garden Woody Plant ID with the OSU Landscape Plant Database’ or the other ‘Elevated Skills’ class offerings. 

Did you miss the training?  Don’t despair ‘Elevated Skills’ training is still open for your learning adventure!  Although in-person sessions of the training have passed, you can still take part and dig deep into a subject of interest.

For Perennial Master Gardeners this training counts as ‘Continuing Education’ hours.

2020 Master Gardeners Trainees, the Elevate training can be counted towards your service hours to meet the requirements to complete the Master Gardener training.

See the entire Elevate course line-up, and register HERE.

Note: The metro area MG program is using a different online tool for our MG Helpline clinic and is not using the ECCO tool being highlighted in the “Learning How to Use the Extension Client Contact Online (ECCO) Tool in Plant Clinic” course.

Washington County Community Garden Survey

Portland Community College is creating a map of current community gardens for Tualatin Soil and Water Conservation District (within Washington County), and then creating a site analysis for possible future gardens.

Their working definition of a community garden is a place where “multiple
families can grow food for the table, not for sale.” Developments that
restrict to their residents or a business that have plots or planters for
their employees all would count (CSAs will not).

If you know of community gardens that meet this definition in Washington County, please complete this survey by May 20: https://forms.gle/gXGvC7sFMBHvUuzf
