I'm wondering if anyone here has any experience with Degroot's Spire. I have three that I planted last year and while they look healthy (dark green) they don't seem to be growing. I planted them 27" apart, hoping to make a dense hedge. Right now, they're about 4 feet tall and 1 foot wide. I'm not so concerned about the height, because I think I've seen growth there. But will these plants ever get wider, and how wide? What I've read online is largely unhelpful, because there seems to be no standard answer to how wide these evergreens get. I don't want to wait ten years only to find that they're no wider than 18". I live about two hours east of Vancouver and my soil has good drainage. They're planted in full sun.
