There is a large bay tree (laurus nobilis) in the back of my garden whose roots are spreading, leading to multiple bay trees sprouting from the ground. This tree is also leaning into my neighbours garden, blocking much of their sun. I would like to take both stems down to the ground. There is also an elderflower tree (Sambucus) from next door whose branches cover half of my garden; I would like to prune these back to the fence (0.5m) a) because I worry they carry a health and safety risk (should they snap in a storm) and b) it leaves my entire garden shrouded in shade, not matter how bright it is. There is also a Yoshino cherry tree (prunus x yedoenis) next door whose branches have spread across my garden, and almost into my next neighbours as well, this also presents a health and safety risk should there be a storm. I would like to prune this back to the fence (1.5m)
