I, myself, have grown tomatoes from the seeds of store-bought ones with success. Every now and then, I'd come across heirloom tomato varieties and I just have to grow them, so I save the seeds. Saving tomato seeds is just as easy as growing tomatoes and you can find out how as you read through.

How To Save Tomato Seeds In 7 Easy Step

We will be using the fermentation process in saving tomato seeds. Apparently, fermentation is a great method for saving tomato seeds as it increases viability by removing any germination inhibitors. Read on for the step-by-step guide:

Step 1. Pick And Slice Tomatoes

You can save and grow tomato seeds from the ones you bought from the store as long as they've been grown organically, but you can always do an experiment of just about any tomato. Pick a ripe tomato variety of your choice to get started.

Step 2. Collecting Tomato Seeds

Take out a chopping board, a knife, and a drinking cup, then prepare your tomato. Slice the tomato in half then squeeze the pulp out into the cup. Add about an inch of room temperature water into the cup with the tomato seeds.

Step 3. Fermenting Tomato Seeds


Take out a paper towel and cover the rim of the cup with it. Put a rubber band around the cup to secure the paper towel cover. This will ferment in three days to a week, depending on how warm your room temperature can get.

Step 4. Tomato Seeds Fermentation Process

You can check your solution after three days, especially if your temperature during these days was around 70 degrees. Check if your solution smells funky or sour, similar to that of yogurt. Check for white fungus growing on the surface of the liquid.

Step 5. Rinsing Fermented Tomato Seeds


Once you find all these signs you can now separate the liquid from the seeds. Add some water to the cup, then pour the liquid out, and the viable seeds will remain at the bottom. You will see the white fungus and mold draining from the cup. Repeat this process at least twice to completely take out the mold and fungus.

Step 6. Collecting Viable Tomato Seeds

After rinsing the seeds, the viable ones will be left at the bottom of the cup. Add some water to the cup and pour all the contents of the cup into a fine sieve. Give the seeds in the sieve a quick rinse and pour them onto a plate covered with a sheet of wax paper.

Step 7. Dry And Store Tomato Seeds

Let your tomato seeds air dry at room temperature. After your seeds have dried out, you can take them out and put them in paper envelopes. Store the seeds in a cool and dark place and they will be viable for up to six years. Now you can try and grow more tomatoes every growing season.
