|Choose the best tomatoes on your plant for seed saving. It's a good idea to choose some of the last fruit of the season and let them ripen fully on the vine. When the tomato dents easily when squeezed lightly, it's time to harvest. Remove the seeds from the tomato, then pick up a dozen or so with the tip of a spoon. Spread the seeds around on an index card and allow the card to dry in an area with good ventilation. Once dry, write the name of your tomato plants on the card, seal them in a heavy zipper-close plastic bag, and store in a cool, dry place. Next spring the seeds will peel from the card easily. |
You should only save seeds from heirloom, open-pollinating type tomatoes.
