“I food saver my excess seeds this year for future plantings for next year, with a silica gel packet; just be aware of ambient humidity when you seal them up,
and know of the viability of the seeds since smaller seeds (onion,chive,carrots,etc.) generally don’t store as long as larger seeds (squash/beans/corn).
Then next year, I will do a germination test, transplant the successes, and figure what seeds need to be replaced for the Spring or Fall garden, and re-order seed accordingly. “
I cut and paste that into my seed directions for this year. And I’ll probably food saver all my prior seeds. Do you recommend freezing them after?
In a word, yes !
The International Seed Vault was chosen for the purpose of retaining and protecting bio-diversity through freezing.
However, the key is not just alone freezing the seed , but also stability of temperature (avoiding significant temperature fluctuations).
