2020 Seed Swap and Scion Exchange


Though we are missing the chance to swap and learn and celebrate the season with all of you in person, we are glad to be able to share some of the spirit of the Seed Swap & Scion Exchange through webinars, lists of helpful resources and links, and the sharing of scionwood. More details and information below!

Talks & Workshops
Each year at the Seed Swap & Scion Exchange, we offer a variety of talks both seed- and tree-related. This year, we have moved some of the talks online. Stay tuned as we add more! See below under "Resources" for recordings of some webinars.

Scionwood Sharing
We have sent bundles of scionwood to various locations throughout the State, and you can pick them up there. Each bundle contains a few kinds of scionwood - think of it as a grab bag! The scionwood will be labeled with the variety. Please only take one bundle of scionwood, and please thank our host sites for helping us share scionwood this year!

Some farm stands are staffed, some are self-serve, and at some locations a cooler is left outside. Please contact farms/stores or check websites for open hours.

If you have things you’d like to swap, or are looking for particular things:

Some of you have reached out to say you are looking for something in particular, or were planning to bring some scionwood or seeds to the swap and still wanted to share. Thank you! We have put together this shared, public, spreadsheet where you can make note of things you have (on the first tab) or special things you’re looking for (on the second tab). Please remember that this can be seen broadly, and do your own due diligence. Here is the link to the spreadsheet.

Members of our community have also suggested the Facebook group “North American Scion Exchange” as a good resource for swapping or purchasing scions with and from others.

Other Helpful Resources

Thoughts on grafting from MOFGA’s Landscape Coordinator, Jack Kertesz:

  • Grafting apples, pear and plums is not that difficult. With practice YOU can do it.
  • Smooth cuts are not absolutely critical but definitely help the union heal.
  • Good alignment and attention to secure taping and sealing are what count the most.
  • A utility knife with a new blade, electrical tape and a Wax Toilet Bowl Seal will suffice. All should be available at any hardware store. (This cheap system works and comes recommended by a number of competent grafters.)

Here’s a grafting primer from the MOF&G archives:

These links give some very clear directions about how to graft:

This one gives clear directions on bud grafting:

This handy PDF has illustrations of different kinds of grafting techniques:

This video cleverly shows how to graft with supplies commonly found on hand:

And here’s a short video on grafting from the folks at Seed Savers Exchange:

Here’s a good resource for caring for your newly grafted tree. Don’t ignore them!


We know there is typically root stock available for sale at the Seed Swap & Scion Exchange.  If you need to order some, try Fedco Trees or Cummins Nursery
B 118 rootstock would be the desired choice for a nearly full size tree that will perform much like a “standard” rootstock, (usually “Antanovka”), preferred by many in colder climates.


Here’s a great resource on how to collect scionwood:

And here’s a helpful video about it:

Apple (and other) varieties
Want to learn more about a particular kind of scionwood you picked up? The Maine Heritage Orchard website has a lot of helpful descriptions, photos and relevant info and links. An excellent reminder of our pomological past and what our future could hold.

This is an exhaustive, alphabetical list of apple, pear, plum and cherry varieties, with comments from growers across the planet.

Your nursery catalogs (or their websites) are also great resources if you want to learn more about a particular variety.

Tree Crops & Regenerative Food Systems
March 31, 2020
Aaron Parker on Tree Crop Commons – Tree and shrub crops are getting some well deserved attention for their climate resilience, low inputs and diverse ecological services. Unfortunately, many people who would otherwise be interested in cultivating trees are unable to, because of lack of long term access to land or the economic necessity of moving around the country. This workshop will discuss several strategies to bring tree crops into cultivation on public lands, where they can be grown for the benefit of people and planet.
Jesse Watson on Permaculture, Agroecosystems and the benefits of a regenerative food system – What does a perennial agriculture look like compared to a tillage-based annual agriculture? What are the functions, products and benefits of a food-producing ecosystem with trees and shrubs as the primary producers? While most people understand that permaculture can be used to design an edible landscape, garden or farm; the potential impact is much greater. Permaculture is much more than an ecosystem design tool.  We will discuss how permaculture can help us design cultural and food-producing systems that may survive and thrive outside of agriculture and civilization.


After the Grafts: Follow-up and Restructuring Concerns on Older Trees
April 2, 2020
A discussion about caring for older trees with Shana Hanson of Three Streams Farm. Shana has been grafting and tending older trees in diverse environments since 1983. We'll discuss:

  • Matching cut size to energy at different parts of a tree, for best healing results
  • Top-working vs. whole-tree grafting, advantages and risks
  • Scheduling or delegating vigilant 1st year sprout removal
  • How to make mindful pruning cuts to maintain growth of multiple scions while grafted stubs close
  • Pruning steps to restore branch spread and spacing
