I moved 4 trees yesterday morning before getting rained out. Two of the cedar trees were approximately 4' tall and you couldn't even tell they were back there; and all of the roots appeared to be within the rootball. The third tree was approximatlely 5' tall and also moved without any problem. The fourth tree was approximately 6-7' tall and again, moved without any problems, but there were roots that stuck out of the rootball. I am going to assume that if I stay with 3'-5' trees, I should have a very good survivability rate. With the rain, I wasn't able to take pictures of the spade at work; but definitely will !! I have to say that it works pretty good, but will be fine tuning my techique with each and every tree.
