How Can I Save Seeds at a Vacuum Seal from the Freezer for Long-Term Storage?

The ancient custom of seed-saving is made simpler with modern appliances. While warmth, light, moisture and oxygen cause seeds to germinate, the opposite states preserve them for future plantings. Vacuum sealing the seeds in a plastic bag and keeping them in the freezer is the greatest process of seed preservation. With this technique, seeds which would only last a couple of years in the first package can stay fresh for up to 10 years or more.

Spread out the seeds on cookie tins with space between each seed, using a different cookie tin for each type of seed in order that they don’t get mixed together. Place the tin in the oven and then flip it on to the smallest possible setting to dry the seeds. Leave the oven door open throughout the drying procedure.

Stir the seeds each hour to encourage even drying. Monitor the oven temperature to make sure it doesn’t exceed 100 degrees and remove the seeds after 6 hours of drying.

Write the name of each seed variety on a self-adhesive label and stick each label onto a different vacuum seal bag.

Put each group of seeds into its individual bag. Insert the open end of their first bag into the vacuum seal apparatus, and press on the button to suck the air out and seal the bag. Repeat the procedure with another bags.

Place the labeled bags in a freezer or refrigerate below 40 degrees.
