Can I keep a leylandii hedge small and/or narrow?
Yes, leylandii can be kept trimmed to any height and width. It is a myth that they can’t be kept small. If you want to keep a leylandii hedge small, you will need to trim it twice a year to keep it looking neat. We have kept a leylandii hedge at 120cm (4ft) tall by 45cm (18 inches) wide for 20 years by trimming it twice a year. There is also a picture of a 90cm (3ft) leylandii hedge on our Hedge Gallery – proof that they can be kept small. To keep a hedge narrow, you need to trim off any shoots/branches coming out of the hedge wider than you want the hedge to be. Do this from the start, as soon as you plant the hedge, and you will encourage the side shoots to grow within the hedge. This will create a narrow hedge that “fills in” quicker.
