Dude! You can plant a garden in Sept?!
I WISH! My garden (I use that term loosly) was a couple of disappointing tomato plants (except the cherry tomatoes), some fat basil, oregano, sage thyme and hot peppers (Cayenes, Japs and Habs).
I think next year I am going to have more basil, only cherry tomatoes (my daughter loves them) and more herbs and peppers. My wife prefers flowers but last time I ate one she freaked, just kidding.
