Trimming Young Leylandii
I planted some sixty 1ft leylandii plants in September 2014 with the aim to grow a thick dense hedge. Now that we have had some sun they are starting to grow well but I'm not sure about how to trim them or if I should. I hear that they trimming them in early spring can make the plant send out more side shoots and make it more dense but should I be trimming a young small leylandii or should I wait until it has started to form a hedge and say 4ft tall? I planted them 2ft apart so hopefully they will form a good strong hedge fast. Am I right in thinking that by not trimming them I would be restricting their growth because trimming them sends them into survival mode and can make them grow 3ft a yaer.
