How to save your heirloom tomato seeds
This works for any tomato seeds, really, but sometimes I come across a rare variety of heirloom tomato that is not only pretty but sweet and juicy. I’m always a little sad thinking that I might never find that variety again. But, with these 5 easy steps, you can easily save the seeds and grow the variety next spring.
- Halve the tomato and squeeze the seeds and pulp into a jar (don’t worry about separating them). Don’t cover the jar completely but if you want to protect the seeds, use a little plastic wrap and poke a small hole in it.
- Ferment the pulp and seeds. Place the jar in a window or warm place for about 2-3 days; mixing the seeds and pulp daily. The seeds will separate from the pulp during this process.
- Clean the seeds. Remove the white film on top with a spoon and place the seeds into a sieve. Wash them repeatedly until they’re clean. Remove as much of the clean water as possible.
- Dry the seeds. Spreading them out in a single layer in a clean place with good ventilation. Let them dry thoroughly, which can take up to a week (especially if it’s rainy). Dry seeds won’t stick to each other and they’ll move quickly across a plate.
- Pack them for the winter. Use a paper or plastic envelope and remember to label them!
Next spring, begin germinating them indoors and by mid-summer, you’ll be able to enjoy the fruits of your labor (literally)!
