Saving Tomato Seeds – Fermentation

TomatoSeeds.JPGThis is a quick reference on how to save tomato seeds.  It will include fermentation which helps remove germination inhibitors and seed-borne diseases.  Only heirloom seeds should be kept because hybrids will not breed true to the parent.

Tools:

  • Cup
  • Water
  • Colander
  • Paper towel
  • Rubber bands
  • Envelope and pen
  • Plate

Steps:

  1. Select the tomato that is fully ripe
  2. Cut  the tomato in half.  Scoop out the tomato seeds and put them in a cup of water about half way full.
  3. Put a paper towel over the top of the cup and put a rubber band around it.
  4. Place the cup in the direct sun for 2 to 4 days.  (Put it in a place where you do not pass by too often since it will start to smell)
  5.  You will know that this process is complete when you see the seeds go down to the bottom of the jar and separate from the pulp.
  6. Use a colander to remove the water from the seeds and rise the seeds under running water.
  7. Place the seeds on a plate and let the seeds dry.  This can take about 2 to 3 weeks.
  8. Place the seeds in an envelope and label it.
  9. Place it in an air tight container such as a canning jar
