Globe Arborvitae - Can I Prune?
Gold Globe Arborvitae planted around patio edge four years ago are getting too big for my taste. How do I prune ANY arborvitae for that matter - there are others that are fifteen feet tall. Can I cut them in half? I think my father - Johnny Appleseed the second - told me once it can be done but there was a proper time of year (?) or a proper way to do it. Why can't I just shear them back?
