Fall is the perfect time of year to start thinking about seed saving! By this point, the end of October, most of the vegetables in the garden have been harvested, and the first frost should be right around the corner. While the gardening season is starting to wind down, a lot can still be done to benefit your kitchen and prepare for next year. Planting garlic for next year’s growing season, and bringing delicate herbs indoors to prolong their harvest are just a few examples of what can be done in the Fall. A favourite of mine is definitely saving your own seed though. A lot of vegetables and flowers will set seed in their first year. Some, like carrots, will only set seed their second year, and the whole plant needs to be over-wintered to reach the seed producing stage. Since most people grow tomatoes, it’s usually the best place to begin if you have never attempted to save seed before.
Seed saving, especially tomato seeds is really quite easy and anyone can do this mini project at home, provided you have grown your own tomatoes. Why start seed saving though you might ask? Wouldn’t it just be easier to go out and buy a few seeds at the local nursery for 2 or 3 dollars? It might be, but consider the fact that most seed packages only contain between 25 and 50 seeds per package. This very quickly starts getting expensive compared to 25 and 75 seeds you could get out of a single tomato at home. An added benefit of saving your own seed is that you can always take part in a local seed exchange as well, which provides the opportunity to meet other gardeners and even picking up some rare varieties!
Seed Saving 101
To start saving your own tomato seeds at home, begin by collecting a handful of the biggest ripest fruit you can find on the plant. Make sure they have not been attacked by bugs, have any signs of disease or other imperfections. The seeds from this fruit will need to be as healthy as possible to give you the best chance at large healthy plants when you go to plant these seeds. Next, wash the fruit in warm water to remove any dirt or insects that may be clinging to it then dry the tomatoes and set them aside. Over a large dish pull the tomato into two, by pushing your thumbs into the blossom end ( bottom) of the tomato. Using your fingers scoop out all the tomato guts, juice seeds the whole nine yards. If you are only saving the seeds from a few tomatoes use a smaller dish that you can simply cover with plastic wrap. Otherwise, you may want to choose a larger container with a sealable lid. The juiced/crushed tomatoes (now seedless) can be saved and frozen to make tomato sauce or this delicious roasted tomato soup.
Fermenting Tomato Seeds
As previously mentioned wrap or seal the container containing the seeds and set in a dark spot such as the corner of a shelf for 3 or 4 days to ferment. The seeds and juice will start to bubble slightly showing that fermentation is happening. This fermentation is good for the tomato seeds as it helps kill any bad bacteria and can increase the seeds resistance to various diseases. It also improves the chance of the seeds germinating next year. If the pulpy mush starts to grow a little bit of mold, don’t worry! Simply stir it under with a clean spoon. The only side effect may be some discoloration of the seeds, which will not affect their ability to grow. I personally like using glass containers and plastic wrap because it lets me see what is going on.
Once the seeds have fermented for three to four days, remove the covering and in a larger bowl rinse the seeds with a good amount of fresh water. Healthy seeds that will sprout should sink to the bottom.
Pour off the pulpy water mix, and rinse the seeds another two times until they look clean and free from any pulpy material. Spread the seeds out on a sheet of paper towel or a clean cloth to air dry. I find it is best to dry the seeds overnight by placing them close to a radiator, but not on the radiator. You just want the warm air from the radiator to help dry the seeds, don’t cook them!
Once the seeds are completely dried it is best to store them in an airtight
container such as a glass mason jar. I bought little 250ml jars which I labelled with the date that the seeds were stored and the variety of tomato. Keep these saved seeds in a cool and dark location for next year’s planting season! The tomato seeds may last up to six years if they were properly fermented, washed, and stored, though most likely they will be used long before then!
