I use a dibble bar (jim gem kbc bar) to plant most of my conservation grade replant trees. works pretty good and goes fast if you have someone to put the tree in the hole. a lot slower if you have to do everything yourself. I also use a 3" auger in the cordless drill for some of the trees just depends on the roots and soil. I will be doing 250 or so trees this weekend and another 100+ the weekend after probably.
