My Dad gave me some seeds that he's had for a few years, and I'm wondering if there is a way to test them to make sure that they are still good, before I try to grow them. I really don't want to waste time, or space, if they are no longer good. I've seen a web site that listed seeds and how long they are still viable, but I'd prefer testing them instead, if that is possible. Is there an easy way to do this? Any help would be greatly appreciated!
