In our neighbours garden (she rents) there's an enormous (compared to the space it's in) tree. The neighbours on her other side have a private road feeding about 6 households. The neighbours have been grumbling because that tree hangs right down, causes sap on their cars and they can't drive past without branches hitting the cars as they drive. They've been asking the neighbour to tell the landlord, she's told him loads of times, (he's sooo bloody slow at
Doing anything g by the way, we've had quite a bit of dealing with him and even the smallest thing takes him months to consider and do anything about - there was a bee nest on his property that was right by our front door and it took him 5 months and a lot of asks to remove) they're now asking us because they know we know him. It doesn't affect us particularly as it's just slightly in our garden but doesn't really have any major affect on our lives. The previous owner had it pollarded and it was fine for many years.
My husband just told the landlord (he's over as he has a lock up on the property) that the neighbours in the other side are getting upset and it's affecting them. He's just said they need to get someone in to cut the overhanging branches - however it's really very overhanging so lopping any branches off will cause it to be a really weird shape, and unless they cut it back totally it'll still cause the sap
What's the 'gardening' rules about this type of issue? Thanks
