How Vegetable Seed Banks Work
Seed Collection
Seeds are harvested from healthy plants.
Cleaning
Plant material and debris are removed.
Drying
Moisture content is reduced for long-term storage.
Packaging
Seeds are sealed in protective containers.
Storage
Seeds are kept in cool, dry, and stable environments.
Germination Testing
Regular testing ensures continued viability.
Best Conditions for Vegetable Seed Storage
Cool Temperatures
Lower temperatures help extend seed life.
Low Humidity
Dry environments prevent mold and deterioration.
Darkness
Protection from light improves seed longevity.
Airtight Containers
Help maintain ideal storage conditions.
How Long Do Vegetable Seeds Last?
Storage life varies by crop:
| Vegetable | Average Storage Life |
|---|---|
| Tomato | 4–10 Years |
| Pepper | 2–5 Years |
| Bean | 3–6 Years |
| Lettuce | 2–6 Years |
| Cucumber | 5–10 Years |
| Carrot | 2–4 Years |
| Radish | 4–6 Years |
Proper storage can significantly extend viability.
