In order to get the best seeds you’ll need to collect from ripe, healthy tomato fruits.

Unripe tomatoes won’t have had enough time to produce mature seeds.
Cut or squash the tomatoes to extract the seeds.
Discard the flesh of the tomatoes, saving only the seeds.

The best way to get rid of the seed coat is to soak the seeds in water for 7-10 days.

After this period most if not all the jelly will have rotted in the water leaving just the seeds.

Pour the seeds in to a seive and rinse with clean running water. A gentle rub with your fingers will seperate any remaining jelly.

Shake the seive to remove as much water as possible before tipping the seeds on to a piece of tissue paper. Seperate the seeds so that they are not touching each other and leave to dry for a further few days.

When dry the seeds can be stored on a dry paper bag

    Excellent instruction.

    That’s exactly the way I prepare and save my tomato seeds.

    Also, store your seeds in a cool dry place to keep them viable longer. Heat and moisture cause the plant embryo in the seed to use up its food supply faster. That’s why seeds die.

    A very good tutorial about saving tomato seeds.

    Remember not to save seeds belonging to hybrid varieties (F1’s) as they will probably not produce fruit the same as their parents.

    Thank you for the useful advice about F1’s seeds not producing the same fruit as the parents.
