My next-door neighbours grew a Leylandii hedge ‘for privacy.’ I can still see into their garden from my rear bedroom, if I want to, and they rarely sit out there anyway. They do keep it trimmed to about 10 feet high, but it keeps the morning sun off my garden. He comes around to my side, with my permission, and trims it, but every time the wind blows more bits drop down. I get tired of clearing them up. The roots impoverish the soil on my side, too, but they are nice friendly people so I let it go.
My diagonally rear neighbours have a beautiful copper beech which is far too big for its position. It overhangs four gardens, including mine, and smothers them with leaves and beech- mast every autumn. It is far too tall for me to trim the overhanging branches. They had the cheek to ask their rear neighbour to get her conifer lopped, and she was silly enough to spend several hundred pounds having it done. It was far smaller and narrower than their tree.
I can live with my minor tree problems, but some of you have major problems. I seem to remember that, when buying house insurance, I am asked if there are any tall trees within a certain distance of my house. You may find that you are either paying extra, or not covered if the trees cause damage. It may be a good idea to check your insurance cover.
