Answer: Blue Prince holly makes an attractive hedge if it is sheared on an annual basis. Each spring you can prune it back to help maintain its size and make it thick and dense. Depending upon how small you intend to keep it, add that size plus 2-3' and plant that far from your house. You'll need the extra 2-3' for good air circulation to keep your plant healthy, and for access to your house for maintenance purposes.
Best wishes with your holly!
