01Open-pollinated only

Only open-pollinated (non-hybrid) varieties reliably grow true from saved seed — hybrid (F1) seed often produces plants quite different from the parent, so check what you're growing before saving.

02What you'll need

Open-pollinated or heirloom varieties
Paper envelopes or jars for storage
A cool, dry, dark storage spot
Labels with variety name and year

03Method

1. Confirm the variety is open-pollinated, not a hybrid.
2. Let seed pods, heads, or fruit mature fully on the plant — well past the eating stage for many crops.
3. Harvest and dry seed thoroughly before storage — damp seed rots or moulds.
4. Clean off chaff and plant debris where practical.
5. Store in a labelled envelope or jar somewhere cool, dry, and dark.

04Troubleshooting

Seed doesn't grow true to type — likely a hybrid variety, or cross-pollination occurred with a related plant nearby.
Seed rots in storage — wasn't fully dry before storing; ensure thorough drying first.
Poor germination next season — seed viability varies by crop; some (like onion) decline quickly, others (like tomato) last years.
Accidental cross-pollination — isolate varieties of the same species if growing more than one for seed.

05Timing & maintenance

Best time

At the natural end of each crop's cycle, once seed is fully mature.

Duration

Seed viability varies widely — a season for some, many years for others.

Maintenance

Check stored seed periodically for moisture or pest issues.

Signs of success

Seed pods rattle when dry, or seed separates easily from fruit and feels hard, not soft.

Pro tip

Start with easy, naturally self-pollinating crops like beans, peas, tomatoes, and lettuce — much lower risk of unwanted cross-pollination.
