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.

But the printed date will give you a sense of how old the seed packet is. If you are only a year or two beyond this date, there's a good chance most of the seeds will still germinate when planted. But if the seed pack is six years old or more, expect to have a much lower percentage of germination.
