Planter Box Sizing

I plan on planting a cedar hedge in a planter box. The mature size of the hedge will be trimmed at 5′-6′ high by 16 inches wide. Would a 16-inch square box per running foot of hedge be large enough? Would freezing of the roots in winter be a issue? Any other advice would be helpful.

The most critical measurement would be the depth of the container. 16″ seems very narrow for a 5-6′ tree, but if that’s what is demanded by your space requirements, you need a container at least 2′ deep, I would guess.
