Free in-person, hands-on training for bud (aka chip) grafting a variety of fruit trees at NE Seattle’s Magnuson Park’s orchard on early evening of Wed 22nd July 2026 6:30 PM to 8:30 PM led by experienced college horticultural instructor.

Were your spring bench grafts this year not 100% successful? Scion wood grafted this past spring which have not yet leafed out as well as produced new vegetative growth probably aren’t viable. Instead of waiting until next spring for another bench graft, rootstock currently with a bad bench graft is ready now for bud grafting.

Or are you looking to graft fruit varieties not as amenable to dormant grafting as pomes? Even as daylight hours already begin to ebb, plenty of time remains for newly harvested buds grafted now to heal before fall then spring forth next year.

On Wed 22 July at Magnuson, some bud wood and rootstock will be brought to the workshop by the instructor for demonstration purposes and additional first-year wood is available for harvest from the adjacent orchard.

Attendees are encouraged to bring your own freshly harvested bud wood as well as rootstock for hands-on creation of your own fruit tree.

Good tips on harvesting first year bud wood is available online at several sites including at: The bud graft or chip budding – People’s Trust for Endangered Species

1. Cut 1st year bud wood close to the growth ring closest to the branch’s tip.

2. IMPORTANT: Unlike dormant scion wood harvesting, first year bud wood has leaves and the leaves need to be removed in order to prevent the bud wood from drying out. Deleaf the bud wood, BUT leave the leaf stalk attached to the branch ensuring no damage to the bud located at the base of the leaf stalk where the leaf stalk connects to the branch. Leaf stalk will also serve as a handle when grafting.

3. Label then loosely wrap deleafed bud wood together before placing cut ends into damp media like sawdust or shredded newsprint. Place everything in container or envelope to retain moisture before storing in cool space like residential refrigerator.

IMPORTANT: If you plan on attending Wed 22 July at Magnuson with the intent to complete specific bud grafts, please RSVP seattletreefruitsociety@gmail.com with what bud wood you plan to bring and what rootstock you may need from STFS. Doing so should help ensure compatible rootstocks are available.

Some of the limited rootstock that can be brought by another STFS member if any attendees RSVP and request:

* Lovell (peach, some nectarine cultivars, some almond cultivars, other stone varieties)

* Marianna 2624 (plum, related stone varieties)

* Bud 9, M111 for apples

* OHxF 087 for pears

* Krymsk 5 for sweet cherries

Even if you have no plans to create your own bud-grafted fruit tree Wed 22 July at Magnuson, still come and observe then start planning for next year when you bud graft your own very special fruit tree.

BRING:

* first year bud wood you harvest and rootstock in which you will be bud grafting. Limited bud wood and rootstock will also be available for demonstration purposes.

* your own rootstock or make arrangements with STFS for rootstock.

* your equipment and materials for grafting. Limited items may also be available from STFS.

* your favorite portable outdoor chair if you plan to sit during the workshop. Limited seating should also be available.

DRESS: For weather and sitting/standing outside for 2 hours. Canopy will be available for unlikely rainy weather. Camping headlamp may also be helpful while bud grafting.

MEET: At the Magnuson Park demo orchard sign installed by longtime STFS member and one of Magnuson Garden’s bests Jerry Packard (RIP). The workshop will be held outside on the concrete pad next to the adjacent The Brig building.

Free in-person, hands-on training for dormant pruning of young (~5-year-old) fruit trees/bushes planted at NE Seattle Ravenna Community Garden on Sat 7th Feb 2026 10 AM to noon led by experienced college horticultural instructor.

Robin Wall Kimmerer knows: Whether the serviceberry or a fig bush or a peach tree, after you plant, baby, plant, you must prune, baby, prune. Pruning fruit plants opens up space where new fresh fruiting wood can grow then set big, yummy fruit to thank you for the dynamic reciprocal relationship you planted and started to nurture years before.

The Ravenna Community Garden (RCG) was laid out in 2010 and planted by volunteers in coordination with Seattle Parks staff. Around 2020, fruit trees/bushes were added to RCG. The Ravenna Community Garden is located at the intersection of NE 68th St. and 21st Ave. NE, NE Seattle & just west of Ravenna-Eckstein Community Center. WARNING: This Ravenna Community Garden (RCG) isn’t the Ravenna P-Patch Community (Secret) Garden which is positioned elsewhere north of the University Village shopping center.

Along with raised beds for vegetables, fruit trees/bushes are planted along the NE 68th St. sidewalk and north/south park walking path. PNW climate-appropriate varieties plugged include: Brown Turkey fig bush, Frost peach tree, Methley Asian/European plum tree, Puget Gold apricot tree, Chojuro Asian pear tree, Hollywood Asian plum tree and containerized blueberry bushes.

Now nearly 5 years later, it’s time to dormant prune these fruit trees/bushes creating scaffolds for growing abundant, quality fruit pieces.

On Sat 7th Feb 2026 10 AM to noon, everyone is welcomed to attend a free in-person, hands-on demonstration by an experienced college horticultural instructor covering:

1) How to dormant prune, for the PNW climate, young (~5-year-old) fruit trees/bushes.

2) How to make a pruning cut that will properly heal.

3) How to assess and thin fruit tree/bush scaffolds for future fruit production.

4) IDing, removing and properly disposing of diseased portions of fruit tree/bushes.

5) What to do with disease-free prunings.

6) How to ID, process and store scionwood harvested from prunings

ATTENDEES: Meet 10 AM at the the Ravenna Community Garden sign installed at the north entrance near the intersection of NE 68th St. and 21st Ave. NE. This event will be outdoors with no seating provided (if needed, please bring your own). Dress for the weather, muddy/uneven walking surfaces and being outside for 2 hours. Public restrooms and heated interior space should be available at the adjacent Ravenna-Eckstein Community Center. Free parking available on street.

No attendees are expected to do anything other than observe and learn. Attendees can bring their own pruning tools and practice supervised pruning cuts. Some related tasks (for example, cutting up prunings and digging up sod under fruit trees) may be performed following the training and volunteer help is welcomed. Scion wood from prunings may be available for distribution to attendees.

STFS and Plant Amnesty Free hands-on, in-person arborist/horticulturist Tool Talk and mature apple tree Summer Prune Demo Sat Aug 9th 10 AM to noon at NE Seattle Magnuson Park orchard led by arborist Ken Tuomi. All welcome to attend.

If your orchard tools could talk … but they don’t, so Ken Tuomi, professional arborist and longtime STFS member, who has led past Plant Amnesty orchard/horticulture tool talks will bring his arborist equipment and discuss select tool applications, limitations and basic care.

Following the show-and-tell portion, Ken will demonstrate operation of select tools as he assesses and summer prunes at least one mature dwarf apple tree in the Magnuson orchard. Summer pruning your mature fruit trees now helps to avoid all that crazy vigorous vegetative spring growth that comes with winter/dormant pruning.

Suggested Stuff to Bring:

*Everything you need for being outside 2 hours with a small group of people.

*Your own orchard tools with related questions or to practice summer pruning a fruit tree with the ready advice of a fruit tree arborist pro.

*Your surplus fruit from your backyard orchard to share … berries, Asian plums/pluots, early season apples, maybe some Breba figs …

*Your own snacks and liquid refreshments. You can decide whether to share or not.

Dress: For weather, dry dirt/dead grass walking surfaces and for gardening chores IF you choose to practice summer pruning (NOT REQUIRED!!!)

Facilities: Spare … Closest toilet is port-a-potty by green P-Patch shed behind The Brig. (Got TP?) Indoor tennis center across intersection may allow use of indoor plumbed toilets.

This Saturday (June 7th) 10 AM to noon, at the NE Seattle Magnuson Park demo orchard, STFS members and friends are thinning apple fruitlets then covering remaining fruitlets with either individual maggot barriers or netting over the entire tree. Everyone is welcome.

To brush up on fruitlet barrier protection, fruitlet thinning and insects that damage PNW apple fruitlets, check out STFS USP newsletter 39 05 2021 May.

Don’t want to fruitlet thin or bag/drape? Saturday’s participants can also help STFS by pruning the “D”s and rootstock suckers or weed creeping buttercup underneath fruit trees.

Maggot barriers will be available for purchase with cash or personal check. 100 heavy weave maggot barriers per package priced at $10 per package. Small quantities of maggot barriers are also available free for attendees to take and test in their backyard orchards. Paying with cash, exact change would be very helpful. Please make personal checks out to “STFS”. All money goes to STFS. Thanks.

The STFS Maggot Barrier How-To webpage offers advice on barrier protecting fruitlets and has been recently updated to include STFS Life member Lori B.’s procedure for applying NovaSource Surround kaolin clay to maggot barriers for added protection. Yes, Surround can only be purchased in 25-pound bags, but STFS Life member Marilyn T. has graciously donated her nearly 25-pound bag to interested attendees. Free 1-cup containers of Surround will be available on Saturday for anyone following Lori B.’s online instructions.

Currently, the Magnuson orchard floor is being cleared to bare ground including removal of the grass alleyways in order to accommodate more fruit plants. Online Magnuson orchard planted varieties map shows what’s already in the ground mostly planted over 20 years ago. What should STFS plant to better demonstrate the fruits that can thrive in PNW backyard orchards? Do you have any uniquely PNW fruit plants, scion or cuttings which you could donate for planting into the Magnuson orchard? Please forward your ideas to STFS’s email (seattletreefruitsociety@gmail.com).

No grift here…FREE in-person, hands-on Fruit Tree Grafting Workshop from a PRO horticultural educator

Sat Apr 5th 2025 10 AM -> noon @ NE Seattle Magnuson Park Orchard

!!!WARNING: This is a FREE LEARNING WORKSHOP for anyone & all to attend!!!

!!!NO attendees are expected to do any WORK!!!

!!!PLEASE: Come, Observe & Learn then LEAVE ASAuPrefer!!!

Bark, bridge, bud, cleft, saddle, side veneer, splice, whip&tongue, … there are many, many different grafting methods for joining parts (scion, rootstock, maybe even an inter-stem between) of similar plants to grow as one plant. That’s the how … then there’s the where…

“Top-working” generally refers to grafting (by various methods) new fruit producing scionwood onto an existing compatible tree already planted outside. “Bench grafting” typically means grafting at a bench or a similar (hopefully warm) interior setting during winter or early spring uniting scionwood and young bareroot rootstock.

On Sat 4/5/25, Ingela will first demonstrate several grafting methods while top grafting plum, prune, maybe apricot scionwood onto a full grown Marianna 2624 rootstock planted years ago in the Magnuson orchard. Later at the nearby picnic table, Ingela will graft apple scionwood onto bareroot rootstock using several additional grafting methods.

A limited amount of free apple rootstock (possibly B9, M111, G41, G935) will be available for the bench grafting demo using apple scionwood brought by attendees. Attendees can take and grow up free apple grafts.

Still want more? After Ingela’s workshop, at least one STFS member will be sticking around to 1) wrap trunks of apple trees with corrugated cardboard for codling moth monitoring, 2) install mason bee cocoons and structures, 3) weed fruit beds and/or 4) layout for upcoming green mulch planting. You can stay to help or to watch or just leave especially if it’s a nice day weatherwise.

Dormant fruit tree pruning … on cold a winter’s day?

Apple and pear tree pruning often occurs in the dormant season (Nov 15 –April 15) which challenges the backyard orchardist when making thinning cuts. Thinning cuts are made to open up sunlight channels into the tree so the best fruit develops throughout the tree and not just at the tree’s top or periphery. Without leaves on the tree during the dormant season, the backyard orchardist must imagine how upper branches may shade out fruit production on lower, more accessible branches. Are you more planner than visionary? An organized backyard orchardist could long-term plan dormant season pruning by flagging branches during the summer for removal the following winter. Doctors are trained to first do no harm, but backyard orchardists aren’t performing brain surgery. Keep in mind the key phrase when dormant pruning: When in doubt, thin it out! Make the most of your thinning cuts and your time spent outside in wet, chilly PNW weather.

Presentation Synopsis (written by Claire Yost)

My presentation will be on my research thesis titled: Regulated deficit irrigation (RDI) conserves water but has limited impact on cider apple fruit and juice quality. RDI is an irrigation management strategy in which the tree is intentional kept in a water deficit, meaning tree water needs (evapotranspiration) exceed water inputs (irrigation and rain). RDI is widely used in wine grapes to conserve water, limit vegetative growth, and improve fruit and juice quality attributes. These positive changes can decrease economic inputs through reducing irrigation and pruning costs. Additionally, fruit and juice attributes such as tannins are increased, leading to a higher value crop. To our knowledge, RDI has not been done in cider apples yet and our research sought to see if cider apples would respond similarly to wine grapes to RDI treatments in Washington state across four cultivars. Furthermore, we evaluated the efficacy of monitoring methods for RDI, which can be used in various irrigation management strategies. These strategies included weather based models, soil moisture and plant water status monitoring.

Here is the complete abstract if you wanted a longer synopsis. (written by Claire Yost) The United States has experienced a resurgence in cider apple (Malus domestica Borkh.) production, with Washington State as the leading apple producer. However, the cider industry is experiencing several challenges, including orchards struggling to meet the demand for cider-specific cultivars, new orchards sometimes having insecure access to irrigation water or only access to high-cost municipal water, and cidermakers trying to differentiate their product in an increasingly crowded market. This project evaluated whether regulated deficit irrigation (RDI) could (1) conserve water while maintaining yield, and (2) increase fruit and juice quality to help producers differentiate their products. The first study evaluated the effects of RDI on tree physiology, fruit yield and quality, and net returns in a partial budget analysis, while the second focused on RDI impacts on juice quality. Trees of four cultivars (Dabinett, Golden Russet, Nehou, and Porter’s Perfection) were managed with either RDI or control irrigation treatments at two distinct locations: Mount Vernon and Wenatchee, WA. In Mount Vernon, no water stress (ψstem) was detected in the trees managed with RDI, though apple weight and fruit phosphorous decreased by 3.9% and 12.5%, respectively, while fruit firmness increased by 1.2% for fruit from trees managed with RDI. In Wenatchee, a decrease in ψstem in trees managed with RDI led to reductions in fruit size (diameter and weight) in both cultivars, bloom density in ‘Golden Russet’, and leaf nutrients (N, P, K, Cu) in ‘Nehou’, as well as increased firmness for both cultivars. Fruit weight decreased by 15.5% and 33.1% for apples from ‘Golden Russet’ and ‘Nehou’ trees managed with RDI, respectively, though there was no corresponding decrease in yield, at least not one that was statistically detectable (P = 0.724 and P = 0.297, for ‘Golden Russet’ and ‘Nehou’, respectively). Irrigation was reduced by 100% in Mount Vernon and in Wenatchee, 40% and 27%, for ‘Golden Russet’ and ‘Nehou’, respectively. These water reductions resulted in a net gain of $347 per hectare with RDI if irrigation was scheduled using a publicly available online tool based on a calculated water balance. However, if irrigation was scheduled based on ψstem for RDI but with the online tool for business-as usual irrigation, the extra labor associated with measuring ψstem resulted in a net loss of $295 per hectare if RDI was implemented. The second study found no changes in juice quality for fruit from trees managed with RDI in Mount Vernon, but in Wenatchee, there was an increase in specific gravity and soluble sugars. However, implementing RDI did not increase total tannins or total phenolics in the juice at either location, nor did it result in meaningful differences in the phenolic profiles of the juice.
