How To Save Tomato Seeds

If you attended one of our Seed Saving workshops, you will know:

1) to have kept your tomatoes isolated from other varieties,

2) picked a mature fruit with the traits that you deem desirable from a range of plants and

3) are only trying to save from open-pollinated varieties.

Notes: It’s actually very easy to isolate tomato varieties because they have perfect-flowers which will self pollinate. We recommend 10-50ft isolation distance between varieties.

If you don’t know if your tomatoes are open-pollinated, research the variety. If “F1” is part of the variety name, or you find that it is a “Hybrid,” this means that the seeds of your tomato plant will not bare true seed. In other words, it’s very unlikely the tomatoes that the next plant bares will be like those of the parent plant. If you want to save seed from your plants, make sure you are choosing open-pollinated and heirloom varieties. Fortunately, plants and seeds sold by Sow True Seed are open-pollinated, since seed saving is part of our mission to empower community and maintain genetic diversity for the sake of food sovereignty!

Step Two:

Squeeze or scrape the seeds into a clean container. I use mason jars. Use a different container for each variety.

Step Three: Add an equal amount of clean (either filtered, or I use well water) to tomato gunk. Stir vigorously. 

For Tomato Seed Saving seeds have to ferment in water as part of the process to break down the seed.

 

Step Four:

Leave the seeds to ferment for 1-3 days (depends on temperature). Cover is optional, you want to keep the fruit flies out, but fermentation will cause gases to build up, so if you seal the jar tight you will need to ‘burp’ the ferment.

Note: The purpose of fermenting is to break down the gelatinous placental covering on the seed.

Step Five:

Stir seeds daily. You will begin to see the seeds sink to the bottom of the jar.

Step Seven:

The remaining seed gloop can be rinsed thoroughly through a metal sieve with the aim of having only clean seeds left in the sieve.

Step Eight:

Leave clean seeds to dry. I like using coffee filters over paper towels because nothing sticks to the seed.

Step Nine:

Completely dry seeds can be stored dry, dark and cool. I achieve this with a small mason jar, a silica gel pack and my basement refrigerator.
