Can seed packets freeze?
As long as your seeds have been able to dry completely, they can freeze without a lot of damage. Since changes of temperature are gradual outdoors, there is less danger of condensation, and winter air tends to keep the seeds dry anyway. The important thing is make sure that the place stays dry. Seed Storage Tip 1: Maintain Cool Conditions Consider a cold closet, a basement, or a room on the north side of your home that remains cool year-round. Freezing isn’t necessary for short-term storage, but you can refrigerate seeds, provided they—and your refrigerator—are sufficiently dry.
Do seed packets need to be airtight?
