How you store the seeds for long term?

Seeds should be kept dry, dark, and cool. I store mine in zippered bags in a box in my basement since my basement is cool and dry. Since the seed packages fit easily inside the bags I know what all the seeds are.

Another method of saving seeds for a long period of time is to freeze them in you freezer. Just like food you want to seal them tightly in a plastic bag and remove as much air as possible so they don't become freezer burnt. I prefer an older type freezer and not the frost free models because they actual raise and lower the temperature in order to defrost the freezer slightly keeping frost from building up but by doing this they are not made to keep a constant temperature which is needed for keeping items for a long time.
