Seed saving closes the loop of home gardening — you grow food, save seeds from your best plants, and grow that food again next year for free. A dedicated seed saver in Michigan can reduce annual seed costs to near zero within 3–5 years while developing plant varieties increasingly adapted to their specific Michigan microclimate.
| Crop | Difficulty | Pollination Type | Isolation Needed? | Michigan Timing | Storage Life |
|---|---|---|---|---|---|
| Tomatoes | Easy | Self-pollinating | Minimal (50 ft for purity) | Let fruit fully ripen on vine (August–Sept), ferment seeds, dry thoroughly | 4–6 years |
| Beans / Peas | Very easy | Self-pollinating | Not needed | Let pods dry on vine through September. Pick before fall rains. | 3–5 years |
| Lettuce | Easy | Self-pollinating | Minimal | Let bolt in July heat; seeds mature August. Shake into bag when seed heads look dry. | 3–5 years |
| Peppers | Easy | Self-pollinating (mostly) | 500 ft for pure varieties | Let fruit turn fully red/ripe (September). Seeds scoop easily from dried fruit. | 3–5 years |
| Herbs (basil, dill, cilantro) | Very easy | Varies | Minimal | Let plants bolt and form seed heads. Harvest when seeds turn brown, before shattering. | 2–4 years |
| Cucumbers | Moderate | Cross-pollinating | 500 ft or hand-pollinate | Let one fruit go fully yellow/orange on vine. Ferment seeds like tomatoes. | 5–8 years |
| Winter squash / Pumpkin | Moderate | Cross-pollinating | 500–1000 ft or hand-pollinate | Cure squash fully; seeds inside are ready to harvest. Different varieties cross — grow one type if saving. | 4–6 years |
| Corn | Difficult | Wind-pollinating | 1000 ft for purity | Let ears dry fully on stalks through September–October. Difficult in small Michigan gardens due to isolation requirements. | 2–3 years |
| Brassicas (broccoli, cabbage) | Difficult | Cross-pollinating, insect | 1 mile (same species cross readily) | Biennials — require two seasons in Michigan. Overwinter root in Michigan basement, replant spring year 2. | 4–5 years |
