Do I need to buy new seeds every year?

Not all farmers have this equipment or the storage space.
Do expired seeds germinate?
Seeds that are only a year old, or slightly older but whose packets are still unopened, generally germinate nicely. If they're several years old, the packs were opened and/or the seeds were stored in less than ideal conditions, subject them to a germination test.
