Pruning Portuguese Laurel
I have just replaced an overgrown leylandii hedge with 2m high rootball Portuguese Laurel. The old stumps were ground out and well-rotted horse manure added. The plants have about 18inches between their foliage, and ideally should be another metre high to obscure an unsightly view. How and when should I prune them to achieve this extra height and also bush out their width as soon as possible?
