For most of my plants I'll be saving, I know how to collect the seeds. It seems every where I've looked to find out how to save seeds, I just find info on how to collect them from the plant/flower...

What I'd like to know is the "after collecting" stage. Do I need to let seeds dry out after I've removed them from the plant before I place them in an air tight bag/container in a cool place? If I am suppose to dry them, how do I do this? Lay them out on a tray for a few days?

Or can I go straight from plant to cool storage with out actually drying them. Please let me know, thanks!
