After 22 years as the Metro-area, OSU Master Gardener Volunteer Coordinator, Jordis Yost retired on July 31st and is starting a new chapter in her life.

We are both excited for Jordis and her family, yet very sad to see her go!

Jordis started her adventure (career) with OSU by taking the Master Gardener training in 1992 with her husband Michael.  Their goal was to get a handle on how to maintain their amazing property in rural Multnomah County.

Jordis instructing 2018 Master Gardener trainees

Jordis believed so strongly in the power of community-based outreach and engagement that she applied for a job with the MG program in 1996.  Since then, she has supported 1000s of volunteers in the Master Gardener training and volunteer experience.

Jordis has embodied the spirit of community and volunteerism during her tenure with OSU.  Patience, a sense of humor, and purpose-driven investment of time and energy are just some of the traits that Jordis has brought to her work.  Jordis also served in volunteer support roles for the Master Recycler, Master Watershed Stewards, and Metro Natural Gardening programs along the way.

Jordis has guided, and educated Master Gardeners with a delightful sense of humor, levelheaded perspective, kindness, and grace.  We are immensely grateful to Jordis for her dedicated service, hard work and steadfast commitment to the OSU Master Gardener program and the Master Gardener volunteers.

Our heartfelt thanks to you Jordis!
Wishing you a wonderful retirement!

 

On September 2nd, OSU Master Gardeners, OSU Extension staff, family and friends gathered to celebrate and honor Jordis.  Here is a snippet of photos from the festivities…

It’s Harvest Season!

Not only in the garden, but also as an OSU Master Gardener volunteer – it’s harvest season!  Time to gather and record your hours of volunteer service and submit your volunteer log sheet, prior to the October 1st deadline.

Metro-area Master Gardeners, you are stellar in your contributions educating and supporting the gardening public, and we want to share that fantastic fact!

The October 1st deadline allows the metro MG program office enough time to compile and share the great news of your tremendous contributions with the state Master Gardener program and OSU Extension Service.

Help us get those statistics to the state level by recording and submitting your hours this month!  We will share the grand totals at our Fall Recertification Training.


New MG Volunteer Reporting System

We are excited to have a new online volunteer reporting system (via Qualtrics) to ease the process of submitting your volunteer hours and signed 2018-2019 Conditions of Volunteer Service form.

To report using the online system – follow the links sent to you in an email from Marcia McIntyre on August 28th

The online system prompts you through several questions to record your volunteer hours, a space to upload your volunteer log sheet, plus the opportunity for you to rate your satisfaction with the Master Gardener program.  A separate link allows you to upload your signed, Conditions of Volunteer Service Form.

You still need to record your volunteer hours onto a Word or Excel form – but now you can upload those hours via the new online system.

NOTE:  You can refer to your CERVIS log to track your hours – but you also need to log all CERVIS hours on your volunteer log sheet.  Most “Program” hours are recorded in CERVIS.  “Partner” events and activities are not recorded in CERVIS.  Be sure to record all your volunteer hours and continuing education hours on your log sheet.

A special thank you to those who have already submitted your hours!  Great going early birds!

For those of you who are still seeking Recertification/continuing education or volunteer opportunities look for some great opportunities below.

Natter’s Notes

Coping with the Heat; Leafrollers on Succulents;
Japanese Beetle Update

Jean R. Natter, OSU Master Gardener


Japanese Beetle Update from ODA

Japanese Beetle

The Oregon Department of Agriculture has completed its main treatment operations for Japanese beetle for 2018. From April 2 to June 1, ODA and General Tree Service, a contracted pesticide applicator, treated approximately 5,800 residences, 5 schools and 4 parks, 2 shopping centers and 1 golf course for Japanese beetle in Washington County. This number was increased from the 2,100 homes treated in 2017. In addition, an area of Portland International Airport and about 30 homes in Oakland, OR, were also treated due to beetle detections in 2017.

 

Community support for the project is very positive. We received consent to treat from over 5,100 residents! This success of this project depends on this kind of support from the community. We also served around 400 administrative warrants to residences from which we had not received a response. Residents have been sending in reports of beetle sightings. Thankfully, almost all of the reports of “serious infestations” of Japanese beetle have been determined to be box elder bug or other pests. [Editor’s emphasis.]

 

The project has entered trapping and detection phase for 2018. Seasonal survey staff are in the process of deploying 5,900 traps to detect Japanese beetle throughout the greater Portland metro area and the northern Willamette Valley. . .

It’s still too early to make any conclusions about success of the project from this season’s data, but early numbers are very encouraging. Our first detection of JB in Washington County this year was on June 17. . .  As of July 21, 2018, we have captured 386 beetles total in the 9 traps. At the same time in 2017, we had captured 2961 . . .  these numbers are early and there are many more traps to check, but a reduction is good news, especially in the most active beetle areas. Final trap catch numbers will tell the whole story, and will be available late Summer/early Fall . . .

 

Our containment operations are also in full swing. Curbside yard debris bin contents are being redirected to Hillsboro landfill, as they were in 2017. Debris moved offsite by landscapers working in the quarantine area are being reminded and encouraged to take debris to our drop-off site at Northwest Landscape services. Residents in the area and landscapers that we have contact information for have been sent two reminders this season. Flyers in English and Spanish are also available on our project website, https://www.japanesebeetlepdx.info/prevention.html.

 

The Oregon Department of Agriculture would like to express its sincere appreciation to the residents in the Japanese Beetle treatment area for their cooperation, as well as all of the partner agencies that have offered support, advice, time and energy to the project. This eradication is one of the largest ever undertaken by the department and would not be possible without the help of the community and partner agencies. This is a multi-year project, and is proposed to continue until 2021. . .  In the meantime, . . .  check for updates on www.JapaneseBeetlePDX.info.


Coping w/ the continuing heat:

– Water early morning (by 6 am) or late day.

– Don’t assume a droopy plant is dry; check the soil with a trowel or finger. Excess soil water can kill.

– Realize that plants (and soil or potting mix) are drying more rapidly than usual. (Blossom end rot is rampant during heat waves because of erratic water supply.)

– Move containers to the shade and/or rig temporary shade 18 inches above sensitive plants.

– Mulch: Add two inches of bark dust or, for shrubs and trees, 4 inches of bark chips.

– Don’t fertilize.

– Mow the lawn high, at 3 inches or so.


Oblique banded leafroller on succulents

Leafrollers and leaftiers are common minor pests of various trees but, this year, the oblique banded leafroller has targeted several succulents, making an unsightly mess of tip growth, precisely where the flower buds should be. The victims: two rather stately sedum cultivars, ‘Matrona’ and ‘Autumn Joy.’ The remedy is simple: Pull the webbing apart and squish the little beasts. See “leafroller and leaftier” in the PNW Insect Management Handbook:  https://pnwhandbooks.org/insect/hort/landscape/common/landscape-leafroller-leaftier.

Natter’s Notes

Blister Mites: Grapes; Pears; Walnuts

Jean R. Natter, OSU Master Gardener

Erineum mite damage on home garden grape leaves: “Blisters” on the top; corresponding concave areas on reverse filled white fuzzy material (enlarged leaf hairs). (J.R. Natter; 2016-04)

Blister mites are running wild this season. It seems that the perfect conditions combined for population explosions of these tiny, elongated mites which noticeably disfigure the leaves of grapes, pears, walnuts, and more. Among pears, even newly planted trees are victims. The symptoms are similar on all three genera but the specific causal agents – also referred to as eriophyid mites or simply eriophyids – vary.

Blister or eriophyid mites reside on the undersides of the leaves, injecting fluids into the leaf tissue as they feed. Those fluids cause the blistering on the top surface with the associated white “fuzz” (enlarged plant hairs) in the concave areas on the reverse. (So, no, it’s not fungal growth.)

Blister mites are far different than the more common spider mites. Adults are microscopic, light in color, cylindrical, tapered at the posterior end, with two pairs of short legs just behind the head. Nymphs are the same but are smaller.

Microscopic image of an erineum mite, Aceria species, elongated, 2 pair legs, size about approximately 1/100-inch. (https://utahpests.usu.edu/uppdl/files-ou/factsheet/eriophyid-mites2010.pdf)

Grape Erineum Mites (Colomerus vitis) are microscopic, wormlike, with 2 short pairs of legs at the head end, and white-yellow in color. They overwinter between the outer bud scales and bud tissue and feed on leaves during spring and summer. Feeding from the undersides of the leaves produces a blistered appearance on the top of the leaves. At the same time, the corresponding depressions on the underside are filled with enlarged light-colored leaf hairs which shelter the mites from natural enemies and pesticides. In spite of how extensive and nasty-looking the infestation is, blister mites seldom affect grape health or production.

As the season progresses, the enlarged leaf hairs progress from white to yellow and, finally, brown. Then, from mid-August until leaf drop, the mites return to their overwintering sites beneath the bud scales.

Home management for grape erineum mites: Sprays aren’t needed. Dormant-season oils and insecticides used for other pests and sulfur applications for powdery mildew usually control this pest.”

Pear Leaf Blister Mites (Eriophyes pyri) feeding causes reddish to yellowish green blisters on the top surface of the leaves, often in 2 lengthwise rows, one at each side of the main vein. With time, the blisters turn brown or black. Leaves may drop prematurely. Loss of excess foliage weakens trees, reduces shoot growth, and interferes with fruit maturation and fruit bud formation. Feeding on fruit causes irregular, russeted spots which feel rough and somewhat scaly. PNW Insect says “Eriophyid mites move from tree to tree, perhaps by wind or carried on birds or insects.”

Home Management for Pear Leaf Blister Mites: Lime sulfur applications in the fall can significantly reduce populations of these mites the following year. (The trick, though is to obtain it in small home-use packaging.) Applications before bud swell can also be effective. Or apply superior oil as buds begin to swell.

Walnut Blister Mites (Aceria erineus)

Just as do the previous two mites, walnut blister mites overwinter beneath bud scales. When springtime temperatures rise, the mites feed among the leaf hairs on the undersides of the leaves. Several generations occur during the summer, which attack new foliage as soon as it unfurls.

Home Management of Walnut Blister Mites: Naturally-occurring predator mites almost always keep mites under control if broad-spectrum insecticide applications are avoided. Heavy rain and cold weather also suppress mite numbers.

Broadleaf weeds like mallow, bindweed, white clover, and knotweed enhance mite numbers. Avoid excessive nitrogen applications, as this encourages mites.

Horticultural oil is the only spray suggested for home-use.

In fond remembrance…
It is with deep sadness that we share the loss of a valued and dear, OSU Extension Service Master Gardener.  Ann Dueltgen passed away on May 22nd, 2018.  Since completing her training in 1999, Ann was dedicated in her service as a Master Gardener.  Ann served alongside, her husband, Bob Dueltgen (training class of 1998).

Bob shared with us that being Master Gardeners was part of their retirement plan.  What a generous plan it was!  Throughout the years you could find Ann and Bob serving their community at Farmer’s Markets (Hollywood was a favorite), garden shows, the Portland Nursery Apple Tasting and the Oregon State Fair.

Ann and Bob combined their volunteer service with the Master Wildlife Stewards program working with area schools, educating students via the creation of wildlife habitats.  Ann and Bob also initiated a partnership with Marysville School and the Multnomah Master Gardener’s Community Demonstration Garden where students learned about composting for the garden.  As Master Gardeners fondly remember Ann, the resounding memory was of her kind heart, and how welcoming and encouraging she was to all she met.  We will miss Ann and are grateful for her two decades of generous service.  On behalf of the OSU Master Gardeners, we extend our sincere sympathies to Bob and his family.

Here is a memorial remembrance of Ann on Oregonlive.

Home and garden use of treated wood.” Selecting the correct type of treated wood can reduce risks to people and the environment. Some preservatives can leach into soil or water and be taken up by plants. Touching treated wood may also leave residues on the skin. Consider that some treated wood may protect against both mold and insects, and some may only protect against molds.” (npic.orst.edu) https://bit.ly/2zmUGOG

How do insects, like aphids survive on a high sugary diet? There’s a reason parents tell their kids to lay off the sugar: too much isn’t good for you.  But small sap-sucking insects called aphids can survive quite nicely on a largely sugar-based diet, despite their inability to make important nutrients from scratch. The key to their success is symbiotic bacteria, which live inside aphid cells and make amino acids, the building blocks of proteins needed for growth.” (University of California, Riverside via lab.manager.com) https://bit.ly/2MgkWjs

How does Rose of Jericho survive in the harsh climate of the desert?  “To survive in a desert, plants must eek out an existence in specific microclimates that provide conditions that are only slightly better than the surrounding landscape. Such is the case for the Rose of Jericho (Anastatica hierochuntica).

Ladybugs, Aphids and the toxic combat that might be happening in your garden. “Aphids are a familiar sight in the garden, sucking the juices out of your rose bushes. Luckily, so are ladybugs, which prey on aphids and keep them in check.  But the relationship between predator and prey is more complex than you might think. Aphids may be important to the survival of some ladybug species we have come to know and love by warding off another predator that has been moving in and feasting on them.” (Veronique Greenwood, nytimes.com) https://nyti.ms/2kZ1M5j

The conclusion of a report from Newcastle University about the removal of neonicotinoid for use in seed treatment of oilseed rape… “Insecticidal control of CSFB in the past has relied on a combination of seed treatment and foliar sprays. The absence of neonicotinoid seed treatments is making CSFB control more challenging for farmers with significant losses of crop identified in the autumn of 2014. The estimated 33,957 kg of a.s. used in the autumn to combat the threat of CSFB represents a 2.5 fold increase in the use of autumn insecticides to WOSR in England and is likely to be a direct result of the ban on neonicotinoid seed dressings. The increased use and reliance on pyrethroids for CSFB control has significant future implications since resistance has now been identified in the UK. The loss of neonicotinoid seed treatments poses a significant challenge to growers at a time when significant price reductions have occurred in the value of this crop, together with an increased threat from the fungal pathogen light leaf spot raising the question for many farmers as to the true value of oilseed rape in the crop rotation.” Read the study: https://bit.ly/2JwanHz
