The local news had the forester on tv saying trees need to by trimmed every 3 to 5 years to kept them safe ? Now we sit around and wonder why people always want trees topped . I do think that having your trees inspected by A pro every 3to5 years(sometimes more depending on the tree ) is good idea but to recommend pruning every time I dont think is a good idea . So was the forserter give good advise ??
