Seed Saving and Storage Guide

Select the best specimens for seed saving. Choose plants that were vigorous growers, abundant producers, and resistant to pests and diseases. Avoid saving seeds from hybrid plants (often marked F1), as they will not grow true to the mother plant; instead, use heirloom, self-pollinated, or open-pollinated varieties.

Harvest the seeds at the correct maturity level. For dry seeds (like beans, peas, or flower pods), allow them to turn brown and leathery or crispy on the plant. For wet seeds (like tomatoes, cucumbers, or peppers), harvest when the fruit is fully ripe but not rotten.

Extract seeds from the plant tissue. For dry seeds, simply remove them from the pods. For wet seeds, separate them from the pulp; for tomatoes and cucumbers, squeeze seeds and pulp into a jar of water and stir twice daily for 2-5 days to ferment and remove the germination-inhibiting gel sac.

Dry the seeds thoroughly. Spread seeds on wax paper in a cool, dry place away from direct sunlight for about a week. For large seeds like pumpkin or squash, a dehydrator set to no more than 100°F for 5-6 hours can be used. Never use an oven to dry seeds.

Verify seeds are completely dry. Use paper towels or newspaper to finish the drying process for seeds that are already fairly dry. Ensure no moisture remains, as damp seeds will develop mold and die.

Store and label the seeds. Place dried seeds in paper envelopes labeled with the seed name and harvest year. Place these envelopes inside an airtight container and store in a cool, dark, and dry location, such as a refrigerator.
