How to Save Tomato Seeds


Tomatoes are a versatile and delicious fruit that can be used in a variety of dishes. However, buying tomatoes from the grocery store can get expensive, and you never know what pesticides or chemicals have been used on them. That’s why many people choose to grow their own tomatoes. Not only is it a cost-effective option, but it also allows you to have control over the quality and taste of your tomatoes. One way to ensure a continuous supply of tomatoes is by saving the seeds. In this article, we will discuss the process of saving tomato seeds and how you can do it at home.

Why Save Tomato Seeds?

Saving tomato seeds has several advantages. Firstly, it allows you to have a constant supply of tomato plants without having to buy seeds or seedlings every year. Secondly, it helps you preserve heirloom varieties that may not be readily available in nurseries or seed catalogs. Lastly, saving seeds allows you to select and save seeds from the best plants, ensuring that the next generation of tomatoes will have desirable traits like taste, size, or disease resistance.

Step 1: Choose the Right Tomato

To save tomato seeds successfully, it’s essential to choose the right tomato. The best types for seed saving are heirloom or open-pollinated varieties. These varieties come true from seed, meaning that the plants grown from saved seeds will be very similar to the parent plant. Avoid using hybrid tomato varieties as the seeds may not produce plants with the same desired characteristics.

Step 2: Harvesting the Tomatoes

Once you’ve selected the tomatoes you want to save seeds from, allow them to fully ripen on the vine. A ripe tomato is typically plump and evenly colored, with no signs of green or unripe spots. Gently twist or cut the tomato from the vine, being careful not to damage it in the process.

Step 3: Removing the Seeds

Removing the seeds from a tomato is a simple process. Start by cutting the tomato in half horizontally. Use a spoon or your fingers to scoop out the gelatinous seed mass into a clean glass or plastic container. You can add a little water to help separate the seeds from the gel.

Step 4: Fermenting the Seeds

Fermenting tomato seeds is an essential step in the seed saving process, as it helps remove the gelatinous coating around the seeds. This coating contains growth inhibitors that can prevent the seeds from sprouting. To ferment the seeds, cover the container with a mesh or paper towel to allow air circulation and prevent mold formation. Place the container in a warm location, around 70-80°F (21-27°C). Stir the mixture daily for about 2-5 days, or until you see a moldy film developing on top.

Step 5: Washing and Drying the Seeds

After the fermentation process is complete, pour the mixture into a fine-mesh sieve or strainer to separate the seeds from the gel and mold. Rinse the seeds under running water, rubbing them gently to remove any remaining gel. Be careful not to damage the seeds in the process. Once clean, spread the seeds on a paper towel or coffee filter and allow them to dry completely. Make sure to separate the seeds to prevent them from sticking together.

Step 6: Storing the Seeds

After the tomato seeds have dried completely, store them in a cool, dry place. The best way to store tomato seeds is in airtight containers such as small glass jars or sealed plastic bags. Label the containers with the variety name and the date of collection for easy reference. Keeping the seeds in a cool and dark location will help maintain their viability for several years.

My 2 Cents

Saving tomato seeds is a rewarding and cost-effective way to ensure a continuous supply of delicious tomatoes. Remember to choose heirloom or open-pollinated varieties for the best results. The fermentation process is crucial in removing the gelatinous coating and promoting seed viability. Lastly, make sure to store your seeds properly in airtight containers to maintain their quality. With a little effort, you can become self-sufficient in growing your own tomatoes from saved seeds and enjoy the fruits of your labor year after year. Happy seed saving!

Additional Tips:

  • If you want to save seeds from multiple tomato varieties, keep them isolated from each other during the fermentation process to prevent cross-pollination.
  • Label your tomato plants throughout the growing season to keep track of the varieties you want to save seeds from.
  • Remember that not all seeds will germinate, especially as they get older. It’s a good idea to test the germination rate of your saved seeds by planting a sample before relying on them for a full crop.
  • Consider sharing your saved tomato seeds with other gardeners through seed exchanges. This helps preserve rare and heirloom varieties and allows you to try new and exciting tomato varieties from other gardeners around the world.
