I had a customer that wanted me to reduce the height of the Arbs. around his patio for a better view from his 2nd story window. These were about 20 ft in height and wanted about 5 feet off. I could see they had been topped once before I would guess several years ago. What are the ill affects of this practice? I don't think it is good for them and I think that it is a poor choice to top for a "view" of your backyard. Also they are his and if I don't do the work, 800 other guys around here will. What is the best thing to do here?
