We have lived in our house for 4 years. Our neighbours have lived in theirs for about 20 years. We have a very large willow tree next to the fence. A fair bit hangs into their garden. Their garden is narrow and doesn't get much light. Our tree shades part of it in the late afternoon, and there are other trees which shade it at other times of the day. Our garden is much larger and wider so we're not affected by lack of sun.
Two years ago we paid about £600 to get the willow pollarded. It was cut right back almost to the trunk. The neighbours were delighted as the man who'd owned our house before us hadn't had the tree pollarded for years. Unfortunately two years on and it's enormous again. We didn't realise quite how quickly willows grow.
The neighbours have let is know that they're going to cut the overhanging branches on their side, which of course is absolutely fine. We have a perfectly amicable relationship with them, but the tree is a source of contention with them (passive aggressive comments about lack of light in their garden etc) and I'm not sure what's reasonable. Should we be offering to have it cut down? We really don't want to - it's a beautiful tree where lots of birds nest and will have been there for decades - probably longer than the neighbours. It would also be extremely expensive - I'd guess close to £2k.
Would be good to hear others opinions.
