The HKBP (Hardy Kiwifruit Breeding Project), organized by Kiwibob Glanzman, is intended to be a Worldwide collaborative effort to create a hybrid Kiwiberry with the smooth skin of the Hardy Kiwifruit (Actinidia arguta) that weighs around 50 grams (about the size of a chicken’s egg), by crossing arguta x chinensis var. chinensis (Kiwi Gold). While progress toward the HKBP goal has been hampered for several years by lack of suitable male pollinators and some unforeseen compatibility issues, 2020 efforts to create a large USA pool of potential male chinensis pollinators have yielded a much larger than expected number of seeds. 

We need to find willing growers to germinate some of these seeds and raise them to the point where they can be evaluated as possible breeding parents in the ongoing hybridization efforts.

In the lower elevations of Western Washington we have a climate where we can grow most species of Actinidia outdoors with little concern of Winter damage. 

As of August 2021, Kiwibob now has many seedlings growing as part of his Kiwi hybridization project – F1 hybrids between Actinidia chinensis & Actinidia arguta, as well as other crosses and open-pollinated seedlings.  Kiwibob is still looking for “foster homes” for these seedlings as they grow and develop.

If you are willing to germinate seeds and have the space to raise the seedlings in pots (about 5 gallon size) for 3-5 years until they can be grafted, then several more years when they can be evaluated, please let me know via the comment form on page A1.02 of my website:

For years, Lori Brakken, Lifetime STFS member, has donated her time traveling to fall fruit shows throughout the Puget Sound area and beyond helping growers identify their treasured mystery apples. As the Covid-19 pandemic lingers, Lori is minimizing in-person activities while maintaining ID outreach.

For apple ID, complete the Apple ID Form (pdf or MS Word document) then follow the attached instructions for contacting then sending apples to Lori. Monetary donations are welcomed which Lori will accept and forward to fund the activities of the Humboldt Preservation Project in Eureka, CA.

Lifetime and longtime STFS member Marilyn T. reported this past Friday (5/21/21) a total of 10 adult codling moths caught already during 2021 in a trap located near the Seward Park area of South Seattle. Reminder: adult codling moths lay eggs on or around pome fruit trees; larvae emerging from these eggs chew into developing fruit leaving behind a dark brown excrement-filled path and core. Yuck.

Always thorough and thoughtful towards amateurs, Marilyn took the time to type out that several nearby (Woodinville and Puyallup) WSU AgWeatherNet weather stations had recorded by last Friday “growing degree day (°F) accumulation base temp 50 °F” or “DD base 50” data of slightly less than 175.

175 is the DD base 50 threshold for first emergence of codling moth and was established from WSU research published in Orchard Pest Management. Marilyn mentions that this threshold is based on observations made in central WA, but also appears to be an accurate predictor in western WA.

In short, Marilyn has observed adult codling moth flying already in Seattle, and nearby WSU weather data coupled with pest management protocols predict codling moth first generation emergence as of now in and around King County. So…

Whatever your strategy to protect your pome fruitlets from codling moth, you should implement it now right after thinning fruitlets to one and only one per cluster.

To lessen COVID-19 spread, the Seattle Tree Fruit Society meeting Saturday May 15^th 10:00 AM to 12:00 PM is only online.The meeting will begin with a brief business meeting, followed by a presentation by author Ann Ralph.

Why Little? Grow A Little Fruit Tree offers a revolutionary vision for backyard fruit trees: a simple and ingenious technique that uses timed pruning to keep fruit trees as short as six feet tall… …they are easy to care for and produce fruit in quantities we’re likely to be able to use. Small trees create the opportunity to have more trees in the backyard and to plant different varieties of fruit to ripen all summer, through fall, and even into winter.

Timed pruning offers a revolutionary approach to fruit tree care, winter prune for shape and summer prune to keep trees small and easy. This presentation covers fruit tree basics: the simple logic of pruning, how to prune for short stature and easy harvest, early training, seasonal routines, and pest and disease control. You’ll learn about the benefits of small trees, getting started, pruning for aesthetics, and how to engage in the pleasures of the pruning conversation.

Ann Ralph is the author of Grow a Little Fruit Tree: Simple Pruning Techniques for Small-Space, Easy-Harvest Fruit Trees. Publishers Weekly called it “a thrilling read for the backyard farmer.” She was the fruit tree specialist at Berkeley Horticultural Nursery and has 20 years of retail nursery experience. She promotes practical, artful, and commonsense methods for the garden generally and fruit trees in particular.

Goodie U, STFS Board Member, reminds everyone that the Ann Ralph zoom meeting will be recorded so attendees not wanting to be recorded should mute microphone and turn off their video. Goodie U made the upcoming Ann Ralph presentation happen. Thanks, Goodie.If you know any non-STFS individual interested in attending this zoom meeting, please forward this zoom invite so more can benefit from Ann’s presentation.

Mike Ewanciw (email mikewan@aol.com) will lead meeting beginning with short business meeting followed by Paul Mallary’s paw paw presentation:

Paw Paws

“The largest native fruit in North America!”

“Floral aroma with consistency like custard”

“A local fruit with a tropical taste”

These sound like pop-up ads for some exotic plant, available for a “limited time only” on the internet. In reality, they describe a mid-western backyard, fence row tree, asimina triloba, that many have heard of but have never seen or grown. For the home orchardist willing to take on the unique challenges of the pawpaw, this tree can fulfill the craving for some exotic eating.

Paul Mallary, long time Western Cascade Fruit Society member, grew up in rural northern Iowa and Illinois on small farms with fruit trees and berries. After serving 4 years in the navy, he obtained a BA in Geography with additional study in Soil Science at the University of Maryland in 1967. Since then, every house he has owned has had fruit trees. While in south King County he inundated his ¼-acre home with over 50 small fruit trees and berries. He recently retired and purchased a home near the Pacific Ocean that will have a new pawpaw patch in addition to 40+-year-old apple and plum trees. Paul is currently the president of the WCFS’s Tahoma chapter.
