Can you plant out of date seeds?
I’m not necessarily recommending out-of-date seeds as being better than, or even as good as, fresh seed. Old seed often has sporadic or very slow germination, and sometimes the plants which do grow are a bit weak and wobbly. But there are many good reasons to keep hold of those old packets.
How long can seeds last before planting?

Should I soak old seeds before planting?
Soaking seeds before planting helps you to break down the seed’s natural defenses against what it expects from Mother Nature, which then allows it to germinate faster. By soaking the seeds, you can quickly boost the moisture content around the seeds, which signals to the seed that it is now safe to grow.
Will old tomato seeds germinate?
Yes! If tomato seeds are appropriately fermented, dried, and stored, they can last up to 10 years with a germination rate of 50%. If used within 4-7 years, the germination rate will be even better. Heirloom tomato pioneer Carolyn Male has re-awakened 22-year-old tomato seeds.
