� To save money � To be self-sufficient � For fun or curiosity � To slow the rate of extinction � As part of a family heritage

Where to start � Sources of seeds
� Local/Regional vs. Canadian vs. International � Non-profits vs. Small seed companies vs.
national/international companies � How you choose will depend on your
motivations
� Choosing seeds also requires some thought about your site � Sunny or shady and size

Maintaining Purity � Population
� How many plants you grow depends on why you’re saving seed
� If you want to maintain varietal health, you’ll
want to grow more than if you’re just growing for yourself.

Maintaining Purity � Isolation
� Pollination
� Self-Pollnating plants require less isolation distance
� Some plants cross-pollinate easily � Bees and Isolation � Flowers to plant between your
plants to slow bees
� Isolate by distance, by flowering time, and by hand

Seed Selection � A common mistake is to save
tomatoes from one plant or a single cob of corn. � Remember diversity is important for
varietal strength.
� You never know what “hidden traits” a plant may have

Seed Selection
� When to harvest � When it’s as dry as
possible – saving wet seeds can lead to problems later on.
� When it’s ripe � Not the same as
when you would eat it.

Drying and Storage � Things to keep in mind:
� If you want to save a large number of varieties, you may not be able to grow them all out every year.
� Silica gel for longer storage � If you want to focus on developing
a variety that’s locally adapted, you will want to grow it out every year.

Drying and Storage � Teeth and hammer tests for dryness � Label your seeds, including year they
were last grown � Seeds should be stored in a cool and dry
place – no plastic!

Drying and Storage � Never grow out all of your seeds!!!! Always
keep some backup, just in case. � Germination testing � Not all seeds last the same.
