Suppose you are an avid supporter of local food. You get your vegetables from the local farmer’s market or CSA, your eggs from your neighbor’s free range chickens, and your bacon from a pastured hog farm where you know the pigs by name. Maybe you’re thinking about taking the next step toward really, really local food–growing it in your own backyard. Or maybe you’ve been gardening for a while and you’re ready to try your hand at saving seeds from your favorite vegetables from season to season, in the process creating locally adapted lines that thrive in your region without the need for heavy applications of pesticides, fungicides or fertilizers.
Well, I am here to help and encourage. Saving seeds from our best vegetables and growing them ourselves is a serious exercise in ProFood principles. ProFood is a growing movement invigorating local and sustainable food systems. ProFood is pro-farmer, or pro-gardener in the case of backyard growers, and saving and growing your own seeds keeps you in control of what is planted and keeps corporations like Monsanto out. It is pro-consumer, pro-cooking and pro-eating, all of which are supported by learning to grow and prepare food ourselves, bringing the freshest, tastiest local produce to the table in the process. ProFood is also an entrepreneurial movement spurring innovation and change within the food system by focusing on developing an alternative, local system and the home grower can become the first link in that new chain. And don’t forget, when those bushels of tomatoes come rolling in around August, you can foster a wonderful ProFood sense of community involvement by sharing the bounty with friends and neighbors.
Tomatoes are generally the first vegetable that people think of when they consider a backyard garden. They’re tasty, popular, and generally easy to grow. The only issue is that some people may be turned off by growing them from seed or saving tomato seeds because it seems complicated and time-consuming, so they resort to buying transplants instead. Problem is, many transplants that you find in stores come from big, commercial nurseries hundreds or thousands of miles away, which may go against the grain of the local, sustainable food movement. Your food dollars are still flowing out of your community, even if the food in question is not quite ready for the plate.
The solution is growing and saving your own tomato seeds. It’s not an arcane science or incredibly difficult, I promise. It’s something anyone can do. You can save seeds this summer from the plants in your garden or even from tomatoes you’ve purchased at the farmer’s market– any ripe tomato will do (see note below about tomato varieties). If you’re saving from your own garden, be sure to select the biggest, healthiest, tastiest plants you have to ensure you’re passing along a robust genetic line. Decide how many tomatoes you want to save from (I usually figure 50-75 good seeds from a Brandywine type, less for smaller tomatoes). From there, it’s just three easy steps involving only about twenty minutes of actual hands-on time to save hundreds of seeds.
Step One: Collecting the seeds
The easiest way to collect seeds from a tomato is simply to slice the fruit in half across the equator and squeeze the ‘goopy guts’ into a bowl. Use your fingers or a spoon to scrape out any stragglers.
Step Two: Fermenting
This is the step where many would-be seed savers get confused or intimidated, thinking it sounds way too complicated, but I’m here to tell you it’s not! You simply have to provide the right environment (a jar and a bit of sunlight) and Mother Nature takes care of the rest. Fermenting is an essential step to remove the jelly-like goo surrounding each seed in order that the seed may germinate and to destroy any disease-causing bacterial or fungal spores that might be hitching a ride.
Transfer your tomato goop into a clear jar, preferably glass, and add a bit of water– you want the consistency runny. Cover the top of the jar with a breathable material like cotton cloth. You can use plastic wrap if that’s what you have on hand, just make sure to poke a few holes in it first.
Now just leave it on a sunny windowsill for about three days. Try to remember to give it a little shake and swirl each day. The top of the mixture will start to look a little scummy and it will smell pretty gross– this is alright! It’s exactly what is supposed to happen. When the process is finished, you should see the good seeds on the bottom with a layer of thick pulp and mold sitting on top.
Carefully pour out the top layer of pulp (it’s great for the compost pile!) and floating seeds (these are not viable and will not germinate). Add a little more water to the jar, swish for a minute, and carefully pour out again. Repeat this until the water in the jar comes out clear. Then, pour the contents of the jar through a strainer to drain the seeds.
Step Three: Drying
The last step is as easy as it sounds. Arrange the seeds in a single layer on a breathable material like paper towels, coffee filters, or a paper plate. Leave in a warm place out of direct sunlight. It helps to have air circulating underneath as well. You can lay paper towels on a cookie cooling rack so that there is adequate air circulation all around or make sure to remember to give the seeds a stir every day so that all sides get some air flow. Depending on humidity, it could take a few days to two weeks for your seeds to be completely dry. You’ll know they’re ready for storage when they not only feel dry, but they are light and easily scoot across the plate or towel when you give it a little shimmy.
That’s it! Now your seeds are ready to be stored until planting time next spring. You can use the small paper or plastic envelopes found in craft stores, or make your own. Store them in a cool, dry place, preferably in an airtight bin to keep the humidity out. Make sure you label them well to prevent any later confusion!
A note about tomato varieties: For the very best results of your seed-saving efforts, try to find heirloom or open-pollinated varieties. These have been bred and inbred over generations to produce consistent and genetically similar seedlings. You can be sure seeds from your Cherokee Purple will produce Cherokee Purple babies.
Hybrid tomatoes are produced through cross-pollination of two different varieties and seeds from hybrids do not generally produce seedlings consistent with the parent type, or, in gardening terms, they don’t “come true” from seed. They tend to revert to the genetic traits of the hybrid’s parent plants, which may not be awful, but it will be unpredictable and probably not as desirable. Also, in a final note, many hybrids are patented or corporate owned. For instance, the popular Early Girl hybrid tomato is owned by Monsanto, whose life-patents and petrochemical dependence make them the very opposite of ProFood.
