As our gardens wind down for the season, it’s time to harvest tomato seeds from our best plants to save for next year’s garden! Today, I want to show you how you can save your tomato seeds for next years planting with 2 different methods, both of which are very simple! Here’s “2 Easy Methods to Save Tomato Seeds for Next Year”.
Before we begin, people often ask if they can save hybrid tomato seeds?
The answer is yes, however, hybrid seeds, also know as “indeterminate” seeds, may or may not give you the same attributes as before. If you’re ok with that, then you can save hybrid seeds. For me, however, I want and need results, so I stick with heirlooms.
For the first method of saving tomato seeds, which is called the “Wet Method”, you’ll need:
- A small pot filled with clean potting soil
- Not-so-fresh tomatoes, not going bad but slightly squishy
- Sharp knife
- Cutting board
- Plastic wrap
Here’s my pot that I filled with clean potting soil. Whatever you use, make sure it’s not too shallow, the roots will need some room to grow.
Simply slice your tomatoes in 1/4-1/2″ or so slices, perfection is not required.
Place the slices on the potting soil like so. Do not water them or cover them with soil!
Don’t worry, the tomato seeds will know what to do!
Cover your pot with plastic wrap.
Place the pot in a cool, dark place until you’re ready to start your seedlings inside! I just put my tomato seeds in a second refrigerator and covered them with paper bags.
If you have a really cold spot in your basement or garage, that could work but it needs to be cold enough (below 50 degrees) for the seeds to stay dormant.
When it’s seed starting time, bring your pot full of tomato seeds out and place it in a warm, sunny window or wherever you start your seeds. Under grow lights would be good too!
You’ll begin to see a LOT of little seedlings coming up!
You can choose the best and strongest ones and pull out the rest. As the seedlings grow, it may become necessary to transplant them into a larger pot before they’re ready to go outside.
How easy is that??!!
Now for the “Dry Method” you’ll need:
- Not-so-fresh tomato
- Small bowl
- Paper towel or napkin
First, quarter your tomato.
Next, with your thumbs, gently scoop out the seeds directly into your bowl.
Put a little water (enough to cover the seeds) in your bowl and let it sit for 3-4 days to ferment. You’ll know it’s ready when it looks really scummy.
This fermentation process helps to dissolve the gel sac around the tomato seeds, which inhibit germination.
Ready! 4 days for me.
Pour your seeds into a strainer and rinse all the scum off, you may want to use your fingers to move the seeds around so they’ll be clean.
Next, put your seeds on a paper towel (placed on a plate of some kind) and let them dry.
You might be wondering how long it takes for the seeds to dry before planting! I set mine outside on a really hot day, the drying process didn’t take long at all! Just make sure they’re good and dry.
Once they’re dry, they might be stuck to the paper towel. Don’t panic, gently scrape them off with your finger nail. If a little bit of paper towel fuzz is still on the seed, it’s ok. That’s preferred over damaging the seed.
Store your tomato seeds in a seed envelope or other container in a dark, cool place until next year!!
