Answer: Seeds will have varying life expectancies depending on what you are growing and how they have been stored. Most seeds will still germinate well enough for another season if they have been stored at an even temperature and stored dry. You can test them by putting some on a damp paper towel, wrapping it in plastic wrap and setting it in a warm location out of direct sun. Check and see what proportion of the seeds germinate. This will tell you if you need to replace the seeds or not.
