DO I NEED TO USE AN HEIRLOOM TOMATO?
You can use whatever you like, a store bought tomato or an heirloom. But the difference is that if you are looking to have a true clone of your tomato, you will need an heirloom tomato. If you are looking at just exploring how to grow tomatoes from seeds for fun, then go ahead and experiment. But understand that a hybrid tomato seeds will not provide you with a clone of the one you grew before or picked up from the store. The taste and look will vary.
Without getting too technical, heirloom tomatoes are open pollinated. Open pollinated meaning that it is pollinated by nature; bees or even the wind when it shakes the plant. Even birds you carefully watch playing and jumping around the yard helps with pollinating when they moves the flower. They all have an impact in pollinating your tomatoes.
An heirloom tomato is an old fashion tomato, as precious as that sourdough starter you baby that is 40 years old.
Gardening is so special, all the tools in the world are available when you garden, but the time you spend taking care of your plants is precious. It will keep on giving!
What is an Heirloom Tomato?
An heirloom tomato has had no cross-breading in 40 years, unlike a store-bought tomato that looks perfect for the taking.
They are bred to look attractive to the buyer and get them to hand over money for the beauty. It may be perfect looking, but the taste is unpredictable and not as delicious.
In the garden, you don’t get the perfect tomato every time, but you get a delicious one, unlike any other. Trust me, my mother who is not a big tomato fan has fallen in love with my garden tomato, the ‘ Orange Accordion Tomato’. The taste is pure and rich, a meaty tomato without a ton of pulp, super delicious. We just had a tomato sandwich and she could not stop saying how delicious the tomato was.
And she has 88 years of experience! And loves cooking and eating!
One other recipe we love is with ground cherries, but you can make this salad with cherry tomatoes. It is so delicious and easy to make, our favorite!
How to Select Your Heirloom Tomato to Start?
I don’t believe in wasting so harvest the green tomatoes because I can ripen them inside. But the best tomato to use for seed collecting is a tomato that has ripened and is healthy. You don’t want a tomato that has rotted, but if it has a dark mark, don’t waste it, you can use it.

HOW TO RIPEN TOMATOES INDOORS FOR TOMATO SAVING SEEDS
So you are ready for tomato saving seeds tips? Let’s do this!
Yes, you can do all the tricks that are on the internet, from placing them on a paper bag together, to adding a banana. But I simply just bring my green tomatoes indoors and leave them on the counter together.
I place them together so that the ethylene will help with making the process to ripen faster. But honestly, you don’t have to. Just leave the tomato on your counter and if your space is a normal temperature and not freezing cold, you will get a beautiful tomato.
How to Slice your Tomato to Get the Most for Tomato Seed Saving
When you are working with tomato seeds, each tomato is different. On a simple round tomato you can cut them in quarters, the cherry tomatoes cut in half, but on an Accordion Tomato, I slice them to get the most pulp and seeds from it.
The accordion tomatoes are very meaty, so they tend to not have as many seeds and also have many little crevices that hold those precious tomato seeds and pulp. I have harvested tomatoes with a handful of seeds and others with many seeds. This is why they are the most precious tomato, for me, to get seeds from.

WHAT IS THE ROLE OF THE TOMATO PULP PLAYING IN SAVING SEEDS FOR NEXT YEAR?
That pulp is an inhibitor, it protects the seed until it is ready to germinate. When you see a volunteer growing, it is a fruit that might have fallen to the ground and when the gel that encloses the seed is washed away eventually with the rain, it gives way to a volunteer. You will be imitating the process indoors and getting your own tomato seed saving method for next year.
You will not need to deal with this inhibitor on every vegetable, for example, the squash varieties. This fruit is a lot easier to save squash seeds from, though some gardeners still like to ferment the squash seeds.
Other examples are beans or pepper seeds that do not require the fermenting process. Learn about the overall practice of seed saving to know what vegetable seeds will require the fermenting process.
How to Remove the Tomato Pulp from the Seed.
After you slice your tomato:
- Scoop out the pulp from the tomato with a spoon. Don’t worry about getting all the pulp mixed with the seeds, it is better to get plenty than miss that precious seed. Scoop away, but be gentle so you don’t damage the seed.
- In a bowl or jar, anything with a wide mouth that you can comfortably insert a large spoon later to scoop, place all the pulp and seeds.
How to Begin Fermentation for Tomato Saving Seeds
- Add water to the jar with the pulp and tomato seeds. You can add the same amount as the pulp. I tend to add more, but it is suggested to add the same amount.
- Place cheesecloth to cover and prevent gnats from getting in the water.
- Allow the mixture to sit in a room between 75 to 80 degrees.
- You will begin to see scum forming on the pulp, on the surface.
- After 2 to 5 days it should be ready for the next step.
- Take a look at the mixture, you will notice the healthy seeds will sink to the bottom of the bowl.
- On the surface you will see the pulp and unhealthy seeds. Add more water if you need to in order to begin scooping out the pulp and bad seeds.
- After discarding the bad seeds, you will be left with the healthy seeds on the bottom.
- Pour seeds into a hand colander and rinse over and over again.
- With your finger or a spoon, gently rub them to finish removing all the pulp as it rinses away.
How to separate tomato seeds from pulp is not a one method process. It is important to remove all of the gel, but you want to skip all the steps and go directly to removing the gel by hand? You can rub it under running water until you get it removed.
With this method, it will take a while to separate the tomato seeds from the pulp, but it will still work.
I tend to be more of a fermenting the seeds type of gardener, easier and less tedious.
Saving Tomato Seeds Without Fermentation
Can you be successful at getting seeds to grow from non fermented seeds? Yes, you can. But keep in mind that heirloom tomatoes will have that gel and it will be more difficult and your success rate will be lower. I don’t take that risk since the process is so simple and doesn’t require any tools that you don’t already have in your own kitchen.
How to Dry Seeds when Saving Tomato Seeds for Next Year
I prefer using a paper plate instead of a paper towel. The seeds will not stick to the surface and will be easier to remove when dried.
Let the seeds dry up completely before storing away. You do not want to put away damp seeds. Dry them in an area that is 75 to 80 degrees and don’t rush the process. I remove any dark seeds that are ready to germinate and keep the beige one. I also make sure to spread them as much as possible to allow them to dry better and so they won’t stick to each other.
The seeds will have a texture to them, almost like tiny hair. If they are smooth, then the gel was not removed properly. This may lower the chances of having them germinate next year, but give them a try. Gardening is not about perfection, it is about the experience and experimenting. I love this part far more than any other.
HOW TO STORE TOMATO SEEDS
You did it! I am so excited when I get my tomato seeds all ready and know I have seeds to grow next year. Nothing like growing your own seedlings! The best ever!
Now that you have your seeds, get your seeds envelop and label it carefully;
- Add Type of Tomato
- Heirloom or Hybrid
- I like to add the year I first grew the plant.
I can’t wait to hear how your seeds do!
Gardening is such an interesting process. If you follow me, you know that I have grown flowers and plants for many decades, but the food is something that I started after and it has been life-changing.
The fun part is when you grow your tomato plant and plant the tomato in the ground and see it grow. Knowing the plant came from your own seed makes everything so much more special.
Don’t be intimidated, you don’t need fancy words, or a chemistry major to try new things. Enjoy every step of the process, you will be amazed how much you grow in a season, as a gardener and as a person.
I grow most of my plants from seed and it inspired me to set up my seed starting station. This is a special space for me that I truly enjoy and think everyone should have this special space to explore the world of the plant’s cycle of life.
Gardening has change not only who I am, but what I am doing with my life today. It all starts with one seed.
