My neighbour has a maple tree on the boundary which is full of mildew and which damages my own plants and my lawn. I have discussed this with her amicably, but she refuses to cut the tree down. This year the problem is worse than ever, is there anything I can do to prevent further destruction of my garden?
You are of course entitled to cut back overhanging branches to the boundary (you have to offer the wood to your neighbour). This may prevent further damage to your garden, but it may also damage your relationship with your neighbour. You will have to decide which is worse.
