Hi, I would like to plant a privacy hedge about 80' long in a sunny location of my yard. I want to keep the hedge prunded in a box shape to a maximum height of 5' and width of 2'. I would like to know what plant would be best suited for this. I was thinking maybe of using emerald cedar or photinia. My personal preference is photinia robusta since I've heard that there can be many problems associated with trying to grow cedar hedges successfully. I don't mind having the work of pruning one or twice a year. I was also wondering if the photinia will provide me with enough privacy since the spaces between the foliage are more open than with cedar hedging. Hoping someone could offer a good suggestion. Thanks.
