I got mine from The Wildlife Group. They are down near Montgomery, AL. The trees were bought bare root and at 2yrs since planting they are 6 to 8 feet tall on average. I got the whole fruit tree package and used the tubes, fertilize and "moisture mizer" granules per their instructions. It costs more up front but is well worth it in the time gained from the increased growth you get right away.
