Tomato Seeds
Tomatoes are a popular seed-saving choice and a good place to start. For tomato seeds, you will need a pint sized canning jar (with its ring) and a piece of paper towel large enough to cover the top. You will also want to have a sharp knife, a spoon, a fork, and a cutting board. Finally, you’ll need a paper towel for drying, labeling paper, and an envelope to store your dry seeds.
The process starts while your tomatoes are still growing on the vine. Choose the tomato that you want to save seeds from and remember no to pick it. It will need to continue to grow till it is just past its ripened state before you cut it off the vine. The next steps are to cut it in half, scoop out the insides into the pint jar and add water until it is half to two thirds full. Using the fork, mash/puree the seed mixture in the jar till it is all separated. Swirl the jar to see if the mix is even. Put the paper towel over the top and fasten it in place with the ring. Let the jar sit on your kitchen counter where you can watch it and swirl it at least once a day for the first two to three days. Let it sit then until it develops a fuzzy moldy looking top. Then add a little more water, swirl, and then let it sit for a minute or so, so the heavy viable seeds settle to the bottom. You can use the fork to lift out and dispose of the slime from the top. Add water, swirl, and let it sit again, then pour off the top mixture leaving the seeds on the bottom. You may have to do this several times until clear water and seeds on the bottom are all that remain. Then pour off the water and dump the seeds on your drying towel. Once they are dry, place them in a labeled and dated envelope and store them in a cool, dry place until you’re ready to plant them next season.
Pepper Seeds
Peppers (Bell, Jalapeno, Poblano, Anaheim, etc.) are another popular seed-saving choice. Just as described above, you want to choose the pepper that you like and want to grow again next year. Cut the pepper open so you can remove the seeds. Put the seeds on a paper towel to dry. Make sure you label your seeds. When they are dry, usually in a couple weeks, soak them in water for a day or so. The seeds that sink to the bottom are your most viable seeds, these are the ones you want to save.
Tomatoes and peppers are a great place to start, but you can save seeds from all of your favorite plants, with a little research. Seed Sowing and Seed Saving, written by Carole Turner, is a good book on how to save seeds and plant them. Also consider your local University of Idaho County Extension Office, your local library, and your favorite bookstore.
