Viability of Seeds Packaged for 2005: Can You Still Use Them?

Most vegetable seeds remain viable 3–5 years if stored cool (35–40°F) and dry. Flower seeds often last up to 5 years. Germination rates decline ~10% per year; sow thicker to compensate.

Storage Tips

  • Keep seeds in zip-top bags inside a sealed container in the refrigerator.
  • Test viability by sprouting 10 seeds on a damp paper towel in a bag; count germinated after 1–2 weeks.

2005-packaged seeds may still germinate, especially if refrigerated. Test a sample before committing garden space.
