Seed Storage:
• Optimal storage is airtight, low humidity, and low temperature.
o Except for peas and beans which like some “open air”.
• Containers should ideally be moisture proof and sealable
(keep in mind that most plastics are not moisture proof).
• Metal, foil-lined heat sealable envelopes are often used at
seed banks.
• Cold storage in a chest type deep freezer is invaluable for
extending the lifespan of seeds. Low temperatures slow the process of seed decay. But be careful, most seeds can tolerate freezing but, it may damage others. Test a small sample of seeds first before putting the whole seed lot into freezer storage.
• Leak, onion, corn and parsnip seed is short-lived, the seed will most likely only last 1 – 2 seasons.
• Always remember that before opening any seed container that has been in a freezer, let the container acclimate to room temperature! If you just open the container straight from the freezer, condensation will form on the interior walls of the container and you will have to dry the seed again (possibly damaging it).
