I'll keep this as simple as I can. My neighbours conifer trees are encroaching into my garden by as much as 7 feet. They were planted only a foot on the other side of the fence and are now about 25 feet tall. Because my garden is lower than my neighbours, I cannot reach the overhanging branches to chop them off. The conifer tree trunks are actually leaning towards my garden. My question is, if I ask a tree surgeon to cut the overhang off, can he chop off the branch at the tree trunk? It would mean encroaching over the neighbours fence by about a foot. Some of the branches are really thick.
