how to save tomato seeds

To save tomato seeds, the process involves extracting seeds from ripe tomatoes, fermenting them to remove the gelatinous coating, rinsing, drying, and then storing. Key steps are:

  1. Cut a ripe tomato and squeeze out the seeds and pulp into a container.
  2. Let the mixture ferment in a warm place (around 70-90°F) for 1-5 days until it becomes bubbly or mold starts forming. This kills off bad seeds and separates the viable seeds that sink.
  3. Skim off the pulp and floating seeds, then rinse the good seeds thoroughly in water.
  4. Dry the seeds on a screen, paper towel, or coffee filter for about 5-14 days, ensuring they are fully dry.
  5. Store the dry seeds in labeled envelopes or airtight containers in a cool, dry place. For longer storage, refrigeration or freezing in airtight containers can keep seeds viable for up to 5-10 years.

Optional shorter methods exist but fermenting enhances seed quality and longevity. Testing germination before storage is advised for best results.
