It’s in the garden of the neighbour at the back, not in my garden, but because it’s so huge it does cast shade in my garden for 1-2 hours a day.
I’ve estimated it’s about 50ft high.
I’ve spoken to the neighbour who is lovely, but not in a position to have it reduced. It’s been there since we moved here 15 years ago, but obviously it’s got way taller and it just keeps growing. It doesn't affect anything although nothing much grows at that end of the garden. It does gives us some privacy as the neighbour’s children have a tree house which would otherwise overlook our garden.
