My neighbours on each side each have a tree close to the boundary. These have grown so large that they meet each other over my garden. This blocks light from my garden, and is obstructing a new shed. Previously I have been able to lop off the odd branch and somewhat control them, but previous occupants (on both sides) have neglected them and they are too big.
WIBU to inform both neighbours that I plan on clearing a lot of the branches over my garden, which will make the tress unbalanced. If I pay, this is what I will be doing (i.e. just paying for the work on my side) but if they want a more sympathetic treatment (at their cost), then I will put the gardener in touch with them.
