Should seeds be soaked 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. Another reason is that while Mother Nature actively assaults seeds, she also gave those seeds an internal gauge to help them know when they should grow.

When should I plant my germinated seeds?
