Natter’s Notes

By Jean R. Natter, OSU Master Gardener

The Winter Cutworm, Noctua pronuba, was officially identified by Oregon Department of Agriculture (ODA) as an invasive pest in Oregon during 2012. Even so, the metro Master Gardener offices had been receiving complaints about their activity since 2001.

Plants were nibbled and/or destroyed from fall through the winter. At first, most folks assumed the damage was due to slugs and snails. However, the mutilation was different than the shredded tissue left behind by slugs and snails. Seedlings were toppled; emerging bulbs lost their heads and sometimes flower buds; and hostas lost leaf tips or had gaping holes. At my place, the pests would climb my 3- to 4-foot tall delphiniums to eat the flower bud at the tip of the stalk, sometimes settling down for a snooze.  To accurately identify the culprits, MGs in the offices had to activate their Master Gardener CSI mode.

The Winter Cutworm, Noctua pronuba

As you likely recall, caterpillars (Order Lepidoptera) have complete metamorphosis, with 4 life stages.  After the adults mate, the female lays several hundred eggs in a large tidy patch, most often covering, or nearly so, the surface of a leaf. The larvae (youngsters) hatch in 2 to 4 weeks. These caterpillars have different habits than most you are familiar with because they feed at night, whenever the temperature exceeds 40F, from fall through winter.

Perhaps the most effective treatment strategy is to go outdoors about 10 pm or so, with a cup of soapy water and tongs or a pair of gloves. As you trek through your plantings keep any eye out for caterpillars chomping at your expense. They may be anywhere from ¾ to 1.5 inches long, the size depending on their age. They’re often aligned with the edge of a leaf, or out-of-sight among the leaves. Hand pick and drop into the cup.

During the day, the larvae hide just under the soil surface, typically quite close to the stem of the victimized plant. Disrupting a bit of soil often reveals their hiding place.

The caterpillars of the Winter Cutworm (Noctua pronuba, aka the Large Yellow Underwing) appear bright green after they have molted; the color will gradually change to the various browns within hours.

Fun for gardeners

This spring, as you prepare your garden, it’s very likely you’ll find a number of Lepidoptera pupae in the soil. Rearing the pupa is the best way to determine the parent moth’s identity.

To rear pupae, place in clear container with a porous lid, such as paper toweling secured with a rubber band. Set the container somewhere you’ll see it, but not in the sun, then wait for the adults to emerge.

The Gray Garden Slug

Slugs, especially gray garden slugs (Deroceras reticulatum) thrive throughout the northwest, feeding in gardens, greenhouses, roadsides and fields. They’re omnivores which feed on live plant material and much more, including mushrooms, dead slugs, earthworms. They have the ability to detect predatory carabid beetles through the use of olfactory cues. And, because slugs are hermaphrodites, reproduction is by cross-fertilization which may occur year-round when conditions are favorable. Mating occurs mainly at night with each animal capable of laying approximately 60-75 eggs (4 mm each) in a clutch, totaling about 700 eggs per year per slug. Each slug may live a year or two.

The Gray Garden Slug (Deroceras reticulum) is perhaps the most damaging slug in local gardens. Damage often avoids (stringy) leaf veins. Source: https://idtools.org/id/mollusc/factsheet.php?name=Deroceras reticulatum

Fun for gardeners

If you happen upon a clutch of slug eggs – they’re transparent and either round or tear-drop shape – scoop them up with a bit of surrounding soil, put them in a clear container with a porous lid, and wait.

Spring has returned.
The Earth is like a child that knows poems.”

– Rainer Maria Rilke




Yes, spring is in the air! With the first day of spring nearing it is time to dust off your OSU Master Gardener badge and get ready for a new slate of MG activities and volunteer opportunities.

Time to reach out and engage in the myriad of Master Gardener clinics, projects and special events.  Return to your favorite Master Gardener activity or try something new! Look for opportunities on CERVIS and in upcoming newsletters and emails.  New MG clinics and events are added every week.

2020 Master Gardener trainees you will have the opportunity to learn about the many volunteer opportunities, week #7 – following which you will be able to register for the activities of your choice.


2020 Master Gardener: In-class Training Home Stretch!

Our 2020 Master Gardener training is humming down the home stretch with just two weeks remaining of our in-class training.  We are grateful to our team of inspiring instructors and extend our hearty thanks to the teams of Perennial MG volunteer coordinators at our three sites!


To our 2020 class of trainees.  We are excited to have you joining our program of committed garden educators.  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.  You will hear about the many OSU approved offerings during week #7 of class.  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 to gain confidence in teaching others how to sustainably and successfully garden.


Key Training Details for 2020 MG Interns:

  • Complete the three required training modules plus the corresponding quizzes, and two additional modules of your choice, along with the quizzes, by March 31, 2020.
  • Complete the online final exam by March 31, 2020. The exam will be available starting March 15th. Please, allocate three to five hours to complete this online learning experience.  You can stop and start the exam, and you can complete the exam in multiple sessions (be sure to save your work).  A score of 70 percent or more is required on the test in order to start volunteering at Master Gardener clinic activities (answering the public’s garden questions). You will receive a grade on the exam upon submission via Canvas.  The exam is open book.  Feel free to refer to your online modules, Sustainable Gardening Handbook, in-class handouts, and confer with your fellow trainees.
