How Long Will Old Seeds Stay Viable?
- Age: All seeds stay viable for at least one year and most will be viable for two years. After the first year, germination rates for out-of-date seeds start to fall.
- Type: The type of seed can affect how long it stays viable. Corn or pepper seeds will have a hard time surviving past the two year mark. Bean, pea, tomato, and carrot seeds can all stay viable up to four years while cucumber and lettuce seeds can last as long as six years.
- Storage conditions: Your old vegetable and flower seed packets will last longer if they are stored in a cool, dark place. Your produce drawer in the refrigerator is a good choice for storage!
