Saving vegetable seeds at home

Saving your own seed costs nothing but a little attention at the end of the season, and it lets you keep a variety going year after year. Not every crop is a good candidate, and hybrids in particular need a different approach.
Open-pollinated versus hybrid
Hybrid (F1) seed will not "breed true" — the next generation is unpredictable and usually disappointing. Only open-pollinated and heirloom varieties reliably grow into the same plant you started with, so check the seed packet or catalog before you plan to save from a crop.
Easiest crops to start with
Self-pollinating crops carry the least risk of accidental cross-breeding with a neighboring variety: tomatoes, beans, peas and lettuce are the standard beginner choices.
Wet-seed versus dry-seed processing
Tomatoes and cucumbers need their seed fermented in its own pulp for a few days to remove a germination-inhibiting gel coating, then rinsed and dried. Beans, peas and lettuce are simpler — leave pods or seed heads on the plant until fully dry and brittle, then thresh out the seed.
Storing it
Seed must be completely dry before storage or it molds. Keep it in a paper envelope, labeled with variety and year, inside an airtight jar in a cool, dark place. Most vegetable seed stays viable for two to five years stored this way; onions and parsnips are shorter-lived and are best used within a year.
