Sovereignty Module: Save the Seed

Complete Seed Saving and Heritage Varieties: From Harvest to Future Harvest
Seed saving ensures food security across generations. This campaign covers pollination, isolation distances, seed harvesting, processing, storage, and variety selection.
Chapter 1: Pollination Types
| Pollination Type | Mechanism | Crossing Risk | Isolation Needed | Examples |
|---|---|---|---|---|
| Self-pollinating | Flower pollinates itself before opening | Very low | 10-25 feet | Tomato, pepper, bean, pea, lettuce |
| Insect-pollinated | Bees, flies carry pollen between plants | High | 1/4 to 1 mile | Squash, cucumber, melon, carrot |
| Wind-pollinated | Wind carries pollen long distances | Very high | 1/2 to 2+ miles | Corn, beet, spinach, chard |
| Perfect flowers | Both male and female parts in one flower | Varies | Varies | Most vegetables |
| Monoecious | Separate male and female flowers on same plant | High | 1/4 to 1 mile | Corn, squash, cucumber |
| Dioecious | Male and female flowers on separate plants | Very high | Need both sexes | Spinach, asparagus |
Chapter 2: Seed Harvesting
| Crop | Seed Location | Harvest Timing | Processing Method | Seeds Per Plant |
|---|---|---|---|---|
| Tomato | Inside fruit | Fully ripe (soft) | Ferment, rinse, dry | 100-300 |
| Pepper | Inside fruit | Fully ripe (color change) | Scrape out, dry | 50-200 |
| Bean/pea | Inside dried pod | Pods dry and brown on plant | Shell, dry | 20-100 |
| Lettuce | Seed heads (after bolting) | Fluffy seed heads | Shake into bag, clean | 500-1,000+ |
| Squash | Inside mature fruit | Fully mature (hard rind) | Scoop, rinse, dry | 100-500 |
| Corn | On cob | Husks dry, kernels hard | Shell from cob, dry | 200-800 |
| Carrot | Seed heads (second year) | Heads turn brown | Cut, thresh, clean | 1,000+ |
| Onion | Seed heads (second year) | Heads dry, seeds black | Shake out, clean | 200-500 |
Tomato seed saving (fermentation method): 1) Select best fruits from best plants. 2) Cut tomato and squeeze seeds with gel into jar. 3) Add small amount of water. 4) Cover loosely (allows gas to escape). 5) Let ferment 2-3 days at room temperature. 6) Mold forms on surface (this is normal and beneficial). 7) Fermentation destroys seed-borne diseases. 8) Fermentation removes gel coating (germination inhibitor). 9) Add water, stir; good seeds sink, debris floats. 10) Pour off floating debris. 11) Rinse seeds in strainer. 12) Dry on plate or screen (not paper towel, seeds stick). 13) Dry completely (1-2 weeks). 14) Store in cool, dry, dark location.
Chapter 3: Seed Storage
| Factor | Ideal Condition | Why | Method |
|---|---|---|---|
| Moisture | Below 8% seed moisture | Prevents mold, premature germination | Dry thoroughly, use desiccant |
| Temperature | 32-41°F (refrigerator) | Slows metabolism, extends viability | Refrigerator or cool basement |
| Light | Complete darkness | Light can trigger germination | Opaque containers |
| Air | Minimal (sealed) | Reduces oxidation | Sealed jars, vacuum bags |
| Pests | Excluded | Insects eat seeds | Sealed containers, diatomaceous earth |
| Crop | Storage Life (ideal) | Storage Life (room temp) | Viability Test |
|---|---|---|---|
| Onion | 1-2 years | 1 year | Germination test |
| Corn | 5-10 years | 2-3 years | Germination test |
| Bean | 3-5 years | 2-3 years | Germination test |
| Tomato | 5-10 years | 3-5 years | Germination test |
| Pepper | 3-5 years | 2-3 years | Germination test |
| Squash | 5-6 years | 3-4 years | Germination test |
| Lettuce | 3-5 years | 1-3 years | Germination test |
| Carrot | 3-4 years | 1-3 years | Germination test |
Chapter 4: Population Size and Genetic Diversity
| Crop | Minimum Population | Ideal Population | Why |
|---|---|---|---|
| Self-pollinating (tomato, bean) | 1 plant (minimum) | 5-25 plants | Maintain vigor, select best |
| Insect-pollinated (squash) | 5 plants (minimum) | 20-50 plants | Prevent inbreeding depression |
| Wind-pollinated (corn) | 25 plants (minimum) | 100-200 plants | Prevent inbreeding, ensure pollination |
| Biennial (carrot, onion) | 5 plants (minimum) | 20-50 plants | Genetic diversity |
Chapter 5: Selection Criteria
| Trait | What to Select For | How to Identify | Why |
|---|---|---|---|
| Vigor | Strongest, healthiest plants | Early emergence, robust growth | Adapts variety to your conditions |
| Disease resistance | Plants that stay healthy | No spots, wilting, or damage | Reduces need for intervention |
| Yield | Most productive plants | Count/weigh harvest | More food per plant |
| Flavor | Best tasting | Taste test | Improves eating quality |
| Earliness | First to mature | Record dates | Extends season, ensures harvest |
| Storage | Longest-keeping fruits | Monitor storage life | Food security |
| Adaptation | Thrives in your specific conditions | Overall performance | Local adaptation over generations |
Reference Card
- Save seed from the best plants (seed saving is selection; choose seeds from your healthiest, most productive, best-tasting plants). 2. Isolation prevents crossing (if two varieties of the same species can cross-pollinate, they will; maintain isolation distances or grow only one variety). 3. Corn needs a crowd (corn is wind-pollinated and requires at least 25 plants for adequate pollination; small plantings produce poorly filled ears). 4. Ferment tomato seeds (the fermentation process removes the germination-inhibiting gel and kills seed-borne diseases; do not skip this step). 5. Dry seeds thoroughly (moisture is the enemy of stored seeds; seeds must be completely dry before storage or they will mold). 6. Cool and dark extends life (seeds stored in a cool, dark, dry place can remain viable for years or even decades). 7. Test germination before planting (place 10 seeds on a wet paper towel in a plastic bag; count how many sprout in 7-14 days to know your germination rate). 8. You are breeding a variety (every time you save seed, you are selecting for traits; be intentional about what you select for).
