Will 20 Year Old Tomato Seeds Grow?

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.

Can seeds germinate after 20 years?

Yes! Even seeds that are thousands of years old can germinate. But proper pre-treatment is essential, and the older the seed, the less energy it has left in storage. Seeds from annual plants aren’t often designed to last many years, part of what makes the germination process so tricky.
