Gardening Question #1: Should I prepare a raised bed for my veggies? And why or why not? What do those that use raised beds use as a border?

Question #2: Can I plant fruit trees in the Winter? I am in Atlanta. How big should/can they be when I plant them?

Yes, I am in the stocking up stage for gerdening books but I would like to take advantage of the massive collective knowledge on this board, while we still can. I have my heritage seeds. I hear they are hard to grow. No matter.

Any other questions or comments are welcome.
