Wow maybe I did it wrong. I just dug the hole big enough to put the gallon jug size root in and deep enough to cover it by maybe an inch over. Maybe your trees are a lot bigger than mine?  My hole was probably 12" around and 18" deep. Our soil here in Alabama is wonderful and it was wet too from the rain so a very easy dig.
