Answer:
Seed vitality or shelf life is an important concept. If you saved seed from last season or the season before or if you’ve been given seed and are not sure how long it’s been around, you might want to perform a seed vitality test a couple of weeks before you plan to sow.
Seeds more than a year or two old may not germinate well or at all, particularly if they have not been stored properly. Some seeds, even after a year of proper storage, may not produce the number of plants you expect or need.
