Store dry seed in clearly marked containers with the species, variety of seed, and collection date, as well as a brief description, written on the outside of the container and on a slip of paper within the container. Small seed is best stored in coin envelopes; use clasp envelopes or a paper clip to hold the envelope closed rather than pasting it shut. 

 

Large-sized seed or greater quantities of seed can be stored in any airtight container. Seeds from commercial vendors may be kept in their original packaging.  

 

Store seeds in a cool, dry location with constant temperature and humidity. Longevity of seed in storage is dependent on storage conditions, the initial quality of the seed, and the seed species. In general, large seeds can be stored for longer periods of time than small seeds.  

 

Before planting in the spring, you should consider testing the germination of the seed you have saved, whether from your own efforts or a commercial grower. Count out up to 100 seeds of small-seeded species, or 25 seeds of larger-seeded types, for the germination test. Fewer seeds can be used if you have limited numbers. Lay the seeds in a line on a paper towel about 2 inches from the edge of the towel. Fold the towel over the seeds and then roll it up like a jellyroll. Moisten the towel, squeeze out excess water, and place it in a plastic bag set in a warm location out of direct sunlight. After 7 days, remove the towel from the bag, unroll it, and count the number of germinated seeds. Determine the germination percentage and adjust your planting plans; over-seeding if need be to make up for poor germination.
