Trimming Hedges (Leylandii?)
Hi All
The large hedge in my garden (I think it's a Leylandii?) was trimmed in early September last year - looking at these photos I have taken of it today, does it need trimming again already? I have read that it is advisable to cut Leylandii hedges regularly but also not to trim them too often either... It doesn't look like it's grown much (I thought Leilandii were supposed to be crazy fast growers?)… could it be left until spring or September next year or would that risk the hedge becoming irreversibly bigger (as I have read you're not supposed to trim these too much in one go either)?
Which brings me to my next question- when is it OK to do it? Not between March and August because of birds nesting. That leaves September to end of February. However, I also read you are not supposed to cut leilandii hedges if there is any risk of frost so that rules out most of that period surely? 
So...
- Has this hedge grown enough to need cutting this year?
- Is early September the only / safest time to do it?

I would trim it by the end of September - that will keep it neat, fresh and green. It's a good looking hedge now - if you left it until September next year it might grow quite a bit and that would mean you'd be cutting back quite hard and possibly into brown wood - that would spoil it.

I have mine cut in October when most of the garden plants are over. In September the chaps tend to damage other garden plants by accident.
That's a good point Muddyfork
If you're getting someone else in to do it they won't always be as careful as you would

I'd give it a trim now , whilst the weather is half decent, to keep it looking good.
Thanks all for the feedback - I feel more reassured now that I'm doing the right thing. Am booking an appointment for the hedge to have a trim!
