I'm going to spend today getting my seed orders ready - looking through the catalogs and websites is so dangerous, even though I have a "plan" for what I want (and have room) to grow, I come across so many things that are just too tempting! Tomatoes may be the worst "problem" - even with canning a lot of salsa, freezing sauce, and whatever else, I really don't "need" more than a dozen plants; but, of course, one must grow extras "in case of a crop failure," and you do have to try new ones to find that special "new favorite."
