Answer: Some of the beans should still be viable after a year, but the germination rate will be lower because of their age. Storage conditions also have a strong effect on viability over time. Planting into overly wet or compacted soil will also reduce your odds of success. You could test the seeds by placing some as a sample on a damp paper towel, wrap it in plastic wrap to keep it moist and set it in a bright location out of direct sun. Check the germination rate and extrapolate that to the rest of the seeds you have.
