this pic is not great, but you get the idea. Two arborvitae flank this office building. Both 8’ tall and fat. One is dead. I’m not sure if it was a gradual death or whether it was a sudden collapse. The area is irrigated. My thought is to replace both trees instead of just one. I think they would always look off kilter if I just replace the dead one. What do you think? I also wonder if they should be replaced by something else. I’d like your thoughts on that as well.
