To ensure that your old seeds will germinate, you should first proof them. Proofing will take two to three days. You need to soak the seeds in a moist paper towel. Then, fold the towel in fours so that it does not touch the seed. Next, place the seeds in a glass or mason jar. To test whether your old seeds will germinate, set the jar or bag aside in a cool, dark place and don't expose it to light.. Website: https://www.authorstream.com/driverpath29/
