Seeds lose viability in storage, especially if exposed to heat, moisture and light. To keep your seeds as fresh as possible for as long as possible, place them in an airtight container and store them in a cool, dark location, like the bottom of a closet or the back of a low cupboard. If stored seeds are many years old, you can check the germination rate by placing 10 seeds on a moistened papertowel and placing the whole thing into a plastic bag. Wait 7-10 days, then count the number of seeds that have sprouted. Divide this number into 10 and you'll have the percentage of germination. You can adjust the number of seeds you plant to match this percentage. For instance if only 50% germinated, you'd plant two seeds instead of one.
