I have a 6 ft tall fence (standard home-store pickets) that was installed before the home was purchased.
A tree, that I assume was planted prior to the fence going up, has grown up through the fence line, so much so that it has pushed the panel in front of the tree off the fence line. I am replacing the pickets and rails due to age/rot.
To work around the tree, I was thinking of using a 4x4 instead of 2x4 for the rails, where I would notch the 4x4 down to 2x4 near the tree. The 4x4 width would be kept near the post to support jutting the fence inward from the normal fence line.
Is there anything I should be concerned with structurally with such an approach?
The tree is primarily in the neighbor's property, so cutting it would not be an option. My concern with new posts is trying to bury such in an existing root structure.
