New privet hedge
I planted bare root privet hedging last November and trimmed back by one third as advised by the nursery where I bought the plants. A year has now passed and all the plants have stared to grow they are about 1 ft high now. My question is when and how do I prune to achieve a good strong hedge. I am aiming at a finished height of about 5 ft and a narrow hedge. The hedge is to provide some privacy and also to give some protection to my veg raised beds from the wind. I have googled but so many different suggestions I am confused. Thanks for any replies.
