Furthermore, will 10 year old seeds germinate? The answer is, yes, seeds will eventually go bad and no longer germinate, but it can take quite a long time. Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.
Regarding this, what happens if you use expired seeds?
No harm will come from using old seeds. The flowers or fruit that come from out-of-date seeds will be of the same quality as if they were grown from fresh seeds. Using seeds from old vegetable seed packets will produce vegetables that are just as nutritious as those from current season seeds.
Are seeds good after 5 years?
Seeds should be stored in cool, dry, dark conditions. To keep the seeds cool (ideally, below 50 degrees), some people store them in a jar in their refrigerator or freezer. Seeds in good condition and stored properly will last at least one year and, depending on the plant, may last two to five years.
