Old Seeds. Good or Bad?
Dampen a thick paper towel. Sprinkle some seeds on the paper towel (you don't have to use all the seeds). Gently roll up the towel and store in a sealable plastic bag. Place the bag in a warm area (about 75°F; the top of a refrigerator works well) and keep away from direct sun. Check the seed packet for number of days to germination, and start checking your seeds a few days before the recommended number. Once germinated, you can transfer the seeds in to a soil medium. You can determine the rate of germination by counting germinated seeds (e.g., if 10 seeds out of 100 germinate you can estimate that 10 percent of the seeds in the packet are viable).
