Jim:
[I recommend an article on seed storage available in PDF. Here is a brief summary:] “Storing seeds by immersion in CALGLY is a simple and cost-effective method for enhancing medium- or long-term longevity of orthodox seeds at ambient temperature.” CALGLY is easily made from readily-available chemicals – Calcium Chloride and Glycerol. The article gives instructions on how to prepare it.
Also, note that this study shows that 2 percent moisture content is the optimum for seed viability. (The article by “Grandpappy” on May 11 [incorrectly] stated that below 5% will kill the seed.) Regards, – Stephen M.
