I've been saving tomato seeds since August, and now that the season is winding down, I'm trying to make sure that I haven't overlooked any of the varieties I want to save for next year. A few of the tomatoes I grew this year were disappointing, or just not very exciting, so I won't be bothering with them again. But I also grew several varieties, including 'Japanese Black Trifele,' 'Polish Linguisa,' and 'Tiger-Like,' that I definitely want to grow again. Because these are all open-pollinated heirloom varieties, I know that I can save the seeds and enjoy them again next year.
If you haven't saved tomato seeds before, you should try it. It's really a very simple process. Since I was saving seeds anyway, I took photos of each step of the process and put together a quick set of step-by-step instructions for anyone who is interested in learning how to save tomato seeds.
On a related note, I'm thinking of putting together a seed exchange here in the forum at About Organic Gardening. If there is some interest in it, I'll go ahead and set up that part of the forum. Please let me know in the comments if this is something you'd be interested in getting involved in.

Colleen,
Did you have the seed swap? Thought you might be interested in the Seed Library I run and our heirloom and organic seed catalog. Our new artist designed seed packs will be online starting in November but if you want a sneak peek let me know!
