Thank you both for the advice! Unfortunately, it has already broken
dormancy. Also, it's a very well established shrub in a boxwood
hedge, and I'm not sure if I could dig it up without damaging the
adjacent ones. For now, I'll be trying the trimming and see if I can
encourage it to fill in. Turning it around will be my ace in the hole
before I resort to replacing it down the road.

Thanks again!
