I remember this from years and years ago; there was always a lot of planning and planning on paper of the whole garden by the adults before anything ever got sown or planted. It seemed silly (to a child) at the time, but there was definitely a method to that particular "madness."
Bright Blessings!
Yes, it's amazing how much time, effort and thought goes into planning out a garden; and when you have a small parcel of land, you really have to be creative.
