Last year my wife and I bought the house where I grew up. We are doing some renovations before moving in. There were a couple of massive willow oaks in the front yard that had to come down. They were much larger than the house and the millions of leaves kept the gutters clogged. The water would spill over and was threatening the foundation. I did not like them anyway and I'm glad they're gone. I decide to replace with a couple of white oak saplings. I found a couple of nice once on the edge of the woods. I transplanted the first and larger one last weekend. That went well enough. The radius of the root ball is the circumference of the tree stem and ground level. These trees are about 15' tall but very skinny. I went about 18" deep in a trench around the ball, then did an undercut. Once it was separated I wiggled a length of burlap under it, and maneuvered it out of the hole and into my UTV wagon. The tree with the root ball weighed a lot (probably 300+#). And I was by myself. So this process got a little dicey and I lost some of the dirt in the process. Still, I got it into the new hole largely intact. My wife kindly held it place as I back filled the hole. It has been watered and mulched. I will keep it wet all summer and hope that it lives.
