My neighbour has a clematis its totally overgrown. I had to replace the fence even though its shared as it brought it down as its so overgrown. She wouldn't replace fence nor contribute. I've told her to keep it at a reasonable height she does not care. I cut it back over my side but its ridiculous. It grows over strangles all my plants killing them. It's sounds petty but it's really invasive. My fence wasnt cheap as it's a large garden. I continually have to cut it and am sick of it. A legal letter she will ignore. Is there anyway of killing it on my side. I font want it taking over. I already have spoke explaining the fence is legally mine she should not be attaching anything to it etc she doesn't care.
