There are many factors that can contribute to this - genetics, environmental storage conditions, etc. Seeds are living organisms that require specific storage conditions in order to remain capable of producing healthy, vigorous plants.

High quality seeds are essential to successful vegetable gardening. While seeds begin the process of losing their viability from the point that they are harvested, with proper conditioning and storage, some species can last for many years.

For commercial vegetable production where high germination rates are a requirement, the following list provides some guidance:. Vilmorin-Andrieux in his book called " The Vegetable Garden " are useful. Click here to view. When storing your seeds, be sure to keep them consistently cool and consistently dry. Temperature and moisture are the primary factors that cause seeds to lose their ability to germinate and fluctuations of these speed the process. Excessive seed moisture increases its respiration rate, can contribute to the growth of destructive micro-organisms, attract insect attack, and reduced viability.

Like moisture, temperature has an influence on the seed's respiration rate. As the temperature increases, so does the respiration rate. Aside from the conditions mentioned above, here are a few more guidelines:. Store in the coolest, driest location available to you avoiding temperatures over 70 degrees Fahrenheit.

These conditions are easily met by placing a small packet of desiccant which maintains a dry environment into a tightly sealed, airtight not airless , glass container and place in your refrigerator.
