My Garden-Fall Planting Planning

I know it is early to be thinking of what I will be planting for the fall season, but since I am new to this, I wanted to sit down with a spreadsheet and see what type of time frame I had for starting my seeds to when they go into the ground. I now know that I have to start thinking about where I want to order my seeds from so that I am not left without anything or having to use less than good seeds. WOW it is a lot of work and you really only have a short window of time to get your plants started and then you have to worry if you have an unexpected season change. I still can't fathom how it was done in the Olden days, but then again that was all they knew (no hoping down to the local grocery store to get fresh (or some semblance there of) of fresh produce, if you did not plant it you did not have it so to speak). I really hope that next year I can get some tomatoes (I won't be doing the upside down method), there must have been something that I did wrong and I hate to have a whole season go by if I can't figure out what it is. Thanks to emilyrhp, her blog helps the beginner get an understanding of the whole process. Nothing like looking at real life photos and reading others comments on how they are doing with their garden, especially one on a smaller scale, like mine.
