Seeds of Diversity has been a supportive entity for Seedy Saturday & Sunday events for many years. During most of these years, our main functions were providing seed packets for Seed Exchange tables and the promotion of events.

Since the COVID-19 pandemic, we have expanded the ways in which we support event organizers across the country. Here are the highlights:

1) Our Seedy Saturday Handbook for planning and executing an event

2) Event promotions - email and we will send you a form for promoting your event details on our Events Page. Why do this? Our page is the only reliable up-to-date national source for organizers, attendees and exhibitors.

3) Virtual organizer planning sessions - we host a number of Zoom sessions each year for organizers to "get together" (virtually!) and chat about challenges, solutions, innovations, and resources.

4) Seed packets! We will send events 20-30 packets of seeds to add to their Seed Exchange table.

5) Virtual presentations on food and gardening issues - our Seedy Saturday Speaker Series. We create a handful of new videos each year that organizers are welcome to use as part of their own event's programming.

Contact for more information and to join our email list to gain access to all of the above supports.

Be sure to check our our Volunteer Resources page, as well!

Seedy Saturday/Sunday Handbook for Event Organizers

Seedy Saturdays are a remarkable phenomenon. They are not one event, but a series of separate events, which have sprung up across the country, each individually and uniquely  organized under the same general themes of encouraging the use of open-pollinated and heritage seeds, enabling a local seed exchange, and educating the public about seed saving and environmentally responsible gardening practices.

What makes a Seedy Saturday (or Sunday or anyday)?

  • Focus on heritage seeds and garden-related knowledge sharing
  • Inclusion of a community seed exchange
  • Non-profit, community-based event
  • Low or no cost for entry

Seedy Saturdays have mainly been organized by individuals and community groups who see a need for gardeners, vendors and organizations to have a low-cost local venue where they can learn from one another, exchange ideas and seeds, and purchase seeds and plants. Gardeners, seed companies, nurseries, gardening organizations, historic sites, and community groups have banded together of their own volition to represent themselves under the umbrella of this unique educational and promotional vehicle, not for the commercial benefit of any one company, group or individual, but for the benefit of all participants: visitors, vendors and exhibitors alike.

 Each Seedy Saturday event is different, because each grows from the effort and ideas of local volunteers. This diversity allows Seedy Saturdays to make the best use of local resources, tailor to regional interests and meet the needs of local audiences. Canada is a diverse country: every Seedy Saturday deserves to be different.

Who can Host a Seedy Saturday?

Anyone and everyone! Seedy Saturdays have been hosted by individuals, volunteer committees, established public sites, churches, gardening groups, non-profit organizations, farmers, and others. Seeds of Diversity does not organize or host individual events, but helps with event promotions and supports local organizers in a variety of ways.

The Role of Seeds of Diversity

Our role in Seedy Saturdays is to:

  • promote events across the country and help coordinate dates
  • participate as an exhibitor when invited
  • offer seed packets for events’ Seed Exchange tables 
  • produce and offer virtual presentations on food and gardening issues for events to use as part of their programming
  • host planning sessions through Zoom for organizers to get together (virtually) and discuss challenges, solutions, innovations, and resources
  • provide educational and support materials: please visit
  • offer mentorship for new organizers

As a non-profit gardening organization, Seeds of Diversity is pleased to participate as a regular exhibitor at all Seedy Saturdays, providing that we can locate volunteers to represent us. Please let us know if you have space at your event for us. 



First, identify the various groups in your area who work with seeds. These can include university plant or pollinator scientists, members of Seeds of Diversity, botanical groups, local organic groups, local wildflower societies, local seed companies who sell open-pollinated varieties, historic museums with heritage gardens, local seed-savers, garden clubs, and so on. Find out who the contact people are, and ask if they would help organize an event. If not, ask them to come as an exhibitor or speaker. 

Once you have a group to help, divide the jobs - examples include: advertising and promotion, food, education, volunteer coordinator, etc. 

Some committees meet quite regularly for months leading up to the event, the others divide tasks and work more independently. In any case, make sure everyone is clear on the budget and have agreed on the tasks and timelines necessary to pull the event off smoothly.


Appendix C features a sample treasurer’s report.


Most Seedy Saturdays are held January-April, giving seed savers time to process and package their seeds from the previous year, but before gardeners need to start seeds for the upcoming growing season.

A few things to consider:

  • Coordinate date scheduling with other Seedy Saturdays in your region so vendors don’t have to choose between events to attend (some vendors will travel >500km for a larger event at which they could have sales). Check events at You can also reach out to us for assistance with knowing about other events’ plans before they’re posted. 
  • Do you want to include seedling vendors? If so, a later date may work better.
  • In many Canadian climate zones, some seeds need to be started indoors by February or March so earlier dates will better accommodate seed sales and swaps.
  • Watch out for Easter, March Break, or conflicting events in your community.


Some smaller communities try to link their Seedy Saturday with a location such as a library or farmer’s market, which brings people out. Others choose locations because they are free, pleasant, a good size, or centrally located. Often organizers have co-sponsors who own a hall which becomes a natural venue for the event.

A few considerations in selecting a venue:

  • Cost
  • Size and number of rooms for exhibitors, presentations and other activities
  • Access to public transit
  • Parking
  • Availability of tables, chairs and A/V equipment


Without promotions, it’s hard to bring a lot of people to your event. A mix of social media, posters and cross-promotions with your partners and vendors will probably be necessary to get the word out – especially until your event is fairly established. Here are a few ideas of ways to advertise:

Social Media & Online Promotions

  • Use Twitter, Instagram, Facebook, and blogs - our handle is @SeedsDiversity on Facebook, Instagram, and Twitter.
  • Encourage vendors and exhibitors to promote through their social media


  • Post at libraries, farmers markets, grocery stores with community bulletin boards, local businesses, local garden-related events etc
  • Give vendors & exhibitors posters to help with promotions at other events they attend

Traditional Media

  • Write a press release for your local media
  • Contact your local tv & radio stations for on-the-day coverage or pre-event interviews
  • Use community newspaper event listings (often free)

In developing your promotions, include the following information: date; time; location; names/logos of all organizing partners; types of vendors; seed swap – encouragement & requirements to get involved; any worshops/presentations being offered; cost/suggested donation



This is really the heart of a Seedy Saturday event. The exchange facilitates the trading or purchasing (for a minimal donation) of seeds saved by local community members. Most organizers have found that their seed swap areas – even if completely unsupervised – are rarely abused. That said, having a volunteer or two at the table can greatly help improve its organization!

Some Seed Swap tips:

  • Get the word out ahead of time that seeds should be packaged and clearly labeled with the type of seed, year saved and ideally the # of seeds included in each package. Any extra information about the variety and where it was grown are great!
  • Have envelopes, pens & labels (masking tape works!) available at the table for those who didn’t do their packaging & labelling ahead of time
  • Have a consistent suggested donation or price for seed packages if you’re making them available to people who didn’t bring their own to trade
  • Create different tables or zones for the different types of materials expected (e.g. seeds, rhizomes, plants) and perhaps further subdivide seeds into smaller categories such as tomatoes, beans, other vegetables, flowers etc.
  • Use lots of signage – if possible, place them up above head level so participants can easily read them even if there’s a crowd.
  • Keep the tables as neat and organized as possible throughout the day to make for easier selection
  • Be prepared to provide lots of bags and boxes of different sizes for the public to carry away their new materials.   
  • Give volunteers distinctive clothing so participants can easily see who to get advice from
  • Have a float with plenty of small change if you’re selling seeds
  • Identify an organization to donate any leftover seeds to

Examples from experienced organizers:

  • In Victoria, each person who brings in seed fills out a registry for each variety, supplying basic information about where the seed was grown and its characteristics 
  • In Winnipeg, seeds are spread out according to type--perennials, annuals, herbs, and vegetables. People are given a ticket for each packet they bring in and can exchange the ticket for another packet of seed. 

Many organizers found that the first year they held this event, few people brought seeds to swap, so don’t be discouraged if the exchange doesn’t take off right away! 


Most events invite a variety of local organizations and nonprofits to have tables at their event. This can be a great way to add educational value, create more local investment, and help attract attendees.


Consider inviting organizations of an organic, horticultural or ecological nature to have tables at your event. Keen organizations may even become partners - helping with promotions and finding volunteers.


Not all Seedy Saturdays include vendors, but including vendors can certainly help boost community interest in your event. Some events do not have any selling of seeds, choosing to keep all the focus on the seed exchange.

If you’re inviting vendors, here are a few things to consider:

  • Will you ask for an advance deposit to hold their spot?
  • Will you charge a table fee? 
  • Will you provide tables? chairs? electricity? Make sure vendors are clear on these items
  • When can they set up? When do they have to tear down by?
  • Ask seed vendors to bring only bring open-pollinated seeds, not hybrids

Write up an agreement so everyone is clear on fees and expectations. 

You may want to consider having all exhibitors and vendors sign waivers, in the unlikely event that their materials or goods are damaged or stolen, or one of their representatives is injured.

See Appendix A for some ideas of exhibitors and vendors to invite. 


Workshops and Speakers: 

You may want to invite local experts in various aspects of seed conservation to speak or conduct a workshop. These experts include the vendors at your event and speakers (assistance sourcing speakers available upon request). 

Appendix B has a list of workshop & presentation ideas. 

You could pay speakers, waive table fees, give gift certificates or simply ask for volunteers.

Workshops often work best run in separate rooms from the vendors and seed exchange. The number of workshops will be affected by how much space you have, how difficult it is to find presenters, your budget for paying speakers, and the number of attendees you expect.  

Children’s Activities:

You may want to consider having a children’s area with activities running throughout the day. These could include: painting and drawing, planting seeds, seed card/papermaking/crafts, Seedy Jeopardy, seedy BINGO, a scavenger hunt or other games. A local 4H club, church, or school may be able to offer some help.

Interactive Displays

Interactive displays are a great way to engage attendees: Observation hives, seed cleaning displays, seed sorting activities and seed ID games are just a few ideas for setting up interactive activities right on the trade show floor. 


Seedy Saturdays should be inexpensive or free to attend. Entry fees generally range from 0-$5, often collected as “suggested donations.” If you’re collecting door fees, don’t forget to bring a sufficient float!

You may want to solicit donations for raffles or door prizes. Exhibitors may be willing to donate gifts, which can be raffled to raise funds. A coat check can also be an effective fundraiser.

Many events collect donations specifically for Seeds of Diversity or other non-profit organizations, or donate a portion of their proceeds.


Clear signage is important so people can find their way to and around your event. Try to include:

  • Large signs or sandwich boards on the road to direct people to your venue
  • Door signs to direct people to various rooms 
  • Signage for donations/admission fees
  • Seed Exchange table signage
  • Large signage for children’s activities, café or any other special areas


Attendance at Seedy Saturdays across the country varies from a few dozen to over 2000.  Events often grow with time as momentum builds and word spreads. Keeping track of attendance and revenue helps with budgeting and planning in the future. It’s also helpful for Seeds of Diversity to track trends across the country from year to year. Even if no fee is charged, handing out door prize tickets is one way to keep track of attendance.


In addition to your organizing committee, you may want to attract some volunteers to help with tasks such as set-up, display staffing, front door, exhibitor hosting, managing the seed exchange table, workshop A/V, and cleaning up. Have a suggestion book on hand that volunteers can write feedback in throughout the event.  


Seeds of Diversity has the following available: 

  • Seed Saving and Pollinator Gardening books
  • Table Setup Instructions & FAQ for Volunteers
  • Biodiversity & Canadian Seed Library posters
  • Table signage for donations 
  • and more; please visit

Contact us at or call 226-600-7782 for assistance. 

We also have our Seedy Saturday Speaker Series, a set of presentations available for playing at events. 

Seed Catalogues

About 2 months before the event send an email to all the heritage seed companies - use the Canadian Seed Catalogue Index or the Seed Companies Map - asking them to mail some copies of their current seed catalogues. At the event, make the catalogues available for people to pick up.
