A new neighbour moved in next door about 6 months ago. A couple of months ago she came round to discuss the lilac tree at the end of my garden as she was concerned it was overhanging the end of her garden. I told her that I was more than happy for her to lop off anything that was overhanging her garden if it was annoying her. in all honesty I'd rather it was left as it is, as it's a beautiful tree, but I know she has every right to take down anything overhanging her garden, and I wouldn't want to spoil her enjoyment of her garden.
Now that I've agreed to let her lop off the overhanging bits, she won't let it go. She has hired some landscape gardeners to transform her garden and has asked which days I am home so that I can let them into my garden to cut off some more tree! She claims that they need to cut branches off at the trunk for the good of the tree. I was so taken aback by this request initially that I just made some noncommittal noises. Since then she's asked several times, and each time I have said that I'm happy for her to take of anything that's overhanging, but that I don't want anyone entering my garden whether I'm home or not. She won't take no for an answer and every day she asks again. I don't want to fall out with a neighbour, but I really don't see why she thinks it's ok to send workmen to my house to do work that I don't feel is needed.
Am I being obstructive, or should she back off?
