I would like some advice on this tree. It is about 8ft tall....the trunk is 2-3 inches across. I believe the root system is in pretty good shape...I know I need to chop the trunk the questions are...where should I cut it? When should I cut it? Should the cut be towards the back or the front of the tree or should it be straight across? Would you put a sealant on the cut if so what? Thanks I appreciate it.
