Bonz, I'm sure someone from your local will give you better info but even in Vermont I can see some reasons for tables. Up off the ground, away from critters, dogs cats and crawler stuff...not to mention little kids and people who might kick them. It is easier to water and to view your trees when they are closer to you. Table tops that are too hot or sunny can be shaded with use of shade cloth etc.

Again someone from your area will give you much more input.
