I found an awesome site with a garden planning gizmo on it which allowed for charting, dating, color graphics etc and.....I did the unthinkable. Rather than spend money to use it and it's wonderful features, I took a drawing pad and planned out all of my gardens using pen, colored pencils and I can even just put dates on when things are planted and other such general information. It works and it is basically free! I have never actually preplanned my planting areas but rather sort of have run by the seat of my pants and planted as I found opportunity. It is actually much faster to use this plan as I am not constantly trying to figure out what I am going to do with each variety.
I have direct seeded all of my tomato and vines and I really think it will work out just fine. If it doesn't then I will swallow my pride and buy plants. If it does work I have enough seeds for next year! Stay tuned!
