I'm making use of the bow saw I got a couple of years ago. It's a wonder I haven't hurt myself.
This is the Leyland that came down after Hurricane Matthew. Since it was a little over 10" in diameter, I had to cut from all sides to get the saw through it. It is a tree we planted.
Here is another tree I planted. It is a red cedar and about half the diameter of the Leyland, though probably about the same age. I cut it down because it is near the septic drain lines which are getting clogged with roots. I don't know if the cedar's roots are the culprit, but I am just cutting down whatever is in the area that I can remove.
Heaven knows what I would cut if I knew how to use a chainsaw!
