Easiest Way to Save Tomato Seeds

Saving tomato seeds is a straightforward process and can be a fun gardening project. Here’s the easiest way to save tomato seeds:

Materials You’ll Need:

  • Ripe, healthy tomatoes
  • A knife
  • A spoon
  • A glass or plastic container with a lid (a glass jar works well)
  • Water


  1. Choose Ripe Tomatoes: Select one or more ripe, healthy tomatoes from your garden. It’s important that the tomatoes you choose are fully ripe because the seeds inside will be mature and ready for saving.
  2. Cut the Tomato: Slice the tomato horizontally. This will give you a cross-section of the tomato. You can save seeds from multiple tomato varieties, but make sure to keep them separate if you plan to grow different types next season.
  3. Scoop Out Seeds: Use a spoon to scoop out the seeds and the surrounding gel-like substance (this is the seed pulp) from the tomato. Place the seeds and pulp into your glass or plastic container.
  4. Ferment the Seeds: To remove the gel coating around the seeds (which can inhibit germination), you’ll need to ferment them. Add a small amount of water to the container with the seeds and pulp. You want enough water to cover the seeds, but not too much to dilute the mixture. Close the lid on the container.
  5. Allow Fermentation: Let the container sit in a warm place, away from direct sunlight, for about 2-4 days. During this time, the mixture will ferment, and you’ll notice that it forms a layer of mold on the surface. This fermentation process helps break down the gel and separate the seeds.
  6. Rinse and Dry Seeds: After the fermentation period, remove the moldy layer and rinse the seeds thoroughly in a fine sieve or strainer under cold running water. The water will wash away the gel, leaving you with clean tomato seeds.
  7. Dry the Seeds: Spread the cleaned seeds on a paper towel or coffee filter in a single layer. Place them in a well-ventilated area, out of direct sunlight. Allow them to dry completely, which usually takes about a week or more.
  8. Store the Seeds: Once your tomato seeds are fully dry, store them in a small envelope or airtight container in a cool, dry place. Be sure to label the container with the tomato variety and the year you saved the seeds.
