Yay! As for the container issue, the columns aren't that thick, so maybe I could keep them to three or four canes max to prevent them growing too wide. There's no space behind the hedge--it butts right up against the stoop, so the container would be on the concrete stoop near the pillar; no way to cut the bottoms out of the containers for them to grow into the ground. I was planning on some pretty large containers, though. So do you think containing the top growth would contain the root growth?
