Have you ever heard the gardening phrase “trained to standard”? This is a method by which you convert a woody vine into a small tree. Over the course of a few years simply eliminate all the side shoots, retaining a single shoot supported with a pole. When the shoot hits the right height — say seven or eight feet — allow the vine to branch out. Pinch the tip of the original shoot to promote lateral shoot growth. This summer, check out the alley behind the Ares Thrift Store on Spruce Street in Boulder. Across the alley there are two trumpet vines that look like trees. In flower they’re phenomenal!
