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 TypeMechanismCrossing RiskIsolation NeededExamples
Self-pollinatingFlower pollinates itself before openingVery low10-25 feetTomato, pepper, bean, pea, lettuce
Insect-pollinatedBees, flies carry pollen between plantsHigh1/4 to 1 mileSquash, cucumber, melon, carrot
Wind-pollinatedWind carries pollen long distancesVery high1/2 to 2+ milesCorn, beet, spinach, chard
Perfect flowersBoth male and female parts in one flowerVariesVariesMost vegetables
MonoeciousSeparate male and female flowers on same plantHigh1/4 to 1 mileCorn, squash, cucumber
DioeciousMale and female flowers on separate plantsVery highNeed both sexesSpinach, asparagus

Chapter 2: Seed Harvesting

CropSeed LocationHarvest TimingProcessing MethodSeeds Per Plant
TomatoInside fruitFully ripe (soft)Ferment, rinse, dry100-300
PepperInside fruitFully ripe (color change)Scrape out, dry50-200
Bean/peaInside dried podPods dry and brown on plantShell, dry20-100
LettuceSeed heads (after bolting)Fluffy seed headsShake into bag, clean500-1,000+
SquashInside mature fruitFully mature (hard rind)Scoop, rinse, dry100-500
CornOn cobHusks dry, kernels hardShell from cob, dry200-800
CarrotSeed heads (second year)Heads turn brownCut, thresh, clean1,000+
OnionSeed heads (second year)Heads dry, seeds blackShake out, clean200-500

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

FactorIdeal ConditionWhyMethod
MoistureBelow 8% seed moisturePrevents mold, premature germinationDry thoroughly, use desiccant
Temperature32-41°F (refrigerator)Slows metabolism, extends viabilityRefrigerator or cool basement
LightComplete darknessLight can trigger germinationOpaque containers
AirMinimal (sealed)Reduces oxidationSealed jars, vacuum bags
PestsExcludedInsects eat seedsSealed containers, diatomaceous earth

Chapter 4: Population Size and Genetic Diversity

CropMinimum PopulationIdeal PopulationWhy
Self-pollinating (tomato, bean)1 plant (minimum)5-25 plantsMaintain vigor, select best
Insect-pollinated (squash)5 plants (minimum)20-50 plantsPrevent inbreeding depression
Wind-pollinated (corn)25 plants (minimum)100-200 plantsPrevent inbreeding, ensure pollination
Biennial (carrot, onion)5 plants (minimum)20-50 plantsGenetic diversity

Reference Card

  1. 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).
