Soak Seeds Before Planting... Is It Necessary? Reasons for Soaking Seeds

What happens to seeds when you soak them?

When you soak the seeds, the water both softens the seed shell and supplies water to the seed interior. Once soaked, seeds and the plants inside them use that moisture to grow and push out new growth.

Not all seeds do well if soaked. Some are too tiny to soak.Every seed is different. With a little research, you can discover what the optimal conditions for your seeds are. 

These are the seeds I have planned to sow in this august month.
