Blimey who knew trees could cause such anger. I have several trees in my garden planted by me and a few that predate me moving in. I love them and despair that I seem to be the only one who has trees. Everyone else just seems to have grass. I did remove about 6 or 7 leylandii about 20 years ago. It didn't cost anything because I did it myself and took the remains to the local tip. As for leaves, yes I get it they are a pain but sweep them up and put them in a black bag stab a few holes and stick them behind the shed or whatever, give it a year and you have lovely mulch, great for the garden and the environment and it's free. I wouldn't dream of damaging anyone's property because it caused shade, I'd grow shade lovers. I keep my trees within reasonable bounds, so trim anything that's causing issues, but they're trees they are meant to be tall. Gardens should not stop at fence height what a stupid idea. Jeez I'm glad my neighbours actually talk to me and I to them and things do not get out of proportion. No I would not ask anyone to pay towards my trees being kept within reasonable bounds and nor would I pay towards theirs. I have two sons who would willingly undertake such work for myself. Our mixed hedge out the front was getting somewhat high recently so my younger son used the tower I had hired to reseal the bathroom window so that he could remove several feet from the top. No one had complained and I'm sure they wouldn't but you don't need complaints before taking action. Same thing last year, neighbour asked if they could trim the branches overhanging their garden out the back. Simple answer was of course and I'll give you a big builders bag to put it all in and my son will sort it out from there. They were over the moon. No need to fall out, I can't see what's going on over the fence but it's no skin off my nose if they remove what I can't see. It's my tree so I take responsibility for disposal, can't say I'd feel the same if they just threw stuff back over the fence. They wouldn't do that though so not a problem.
