2:45 pm  Hydro-Mulching (Sprayable Mulch) for Sustainable Agriculture, Ben Weiss

Many Plants benefit from mulches, including fruit crops. Unfortunately, most mulches are made from non-degradable plastics that can pollute terrestrial and aquatic ecosystems. This presentation will introduce a new mulch technology, biobased and sprayable hydromulches, which are suitable for organic production and could be a more sustainable alternative to non-degradable plastic mulches.   

NOTE:  Bare root strawberries are sold out and will not be offered at the event. 

We hope you can join us on Saturday!

STFS in-person meeting @ Sky Nursery featuring Ingela Wanerstrand talk Selecting Fruit for PNW Gardens Sat Mar 4th 10 AM-noon

Selecting Fruit for PNW Gardens – What fruits make sense to grow in your own PNW garden rather than paying many dollars at the store? Even in a compact urban backyard, layers of fruit plants from alpine strawberry ground cover to dwarfing multi-cultivar fruit trees can convert sunlight into healthy fresh fruit at arm’s length. Experienced horticulturist and educator Ingela Wanerstrand dba Green Darner Garden Design will cover why you might want to grow your own, plants that consistently fruit in the PNW and ideas for fruit-growing in small spaces. In-stock Sky Nursery fruit plants will be featured during Ingela’s talk.

Everyone is welcome to attend.

When: next Saturday (March 4th) 10 AM to noon; 10:00-10:30 socialize, 10:30-11:00 STFS meeting & 11:00-noon Ingela’s talk. More details in attached handout.

Where: Sky Nursery (18528 Aurora Ave N Shoreline, WA 98133, Store open 9-6 Daily, phone 206.546.4851 email just north of Seattle.

Venue is a large, airy glass-enclosed greenhouse space with apparent good ventilation and probably will be cooler than comfortable so wear an extra layer. Sky has no COVID-19 PPE requirements, so participants need to take COVID-19 precautions they feel are necessary.

Please DON’T BRING REFRESHMENTS TO SHARE WITH OTHER ATTENDEES; Sorry, Sky has requested that due to public participation and lingering COVID-19 concerns, no refreshments be provided by STFS members to share potluck-style with other participants.

STFS maggot barriers no longer available as of Feb 2023

As of February 2023, Seattle Tree Fruit Society (STFS) no longer is selling maggot barriers (MBs) for funding STFS educational activities.

MBs can now be easily purchased over the internet (search: maggot barriers), through Amazon or at area nurseries. Recently, in the Seattle area, nurseries stocking MBs have included Sky , Swansons , Cloud Mountain (Everson) , West Seattle , Sunnyside (Marysville) , Squak Mountain (Issaquah) , City People’s Sandpoint , & My Garden Nursery (Bellingham). Please contact these reputable nurseries directly to check for MB availability.

The STFS website still provides instructions for covering fruitlets with MBs.

Hardy Kiwifruit Breeding Project

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:

When you visit the website, be sure to download the most recent HKBP Report from page A1.02, and review all previous Reports!

Codling Moth 1st generation 2021 have begun flying in King County

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.

STFS zoom-only meeting Saturday May 15th 10:00 AM – 12:00 PM featuring author Ann Ralph talks about Grow a Little Fruit Tree: Simple Pruning Techniques for Small-Space, Easy-Harvest Fruit Trees

To lessen COVID-19 spread, the Seattle Tree Fruit Society meeting Saturday May 15th 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.
