Cupressocyparis Gold C4 – Leylandii

Leylandii Castlewellan Gold is the most popular Golden Leylandii.  It is a fast-growing conifer that forms a dense, evergreen hedge providing a screen all year round. Castlewellan has golden-yellow foliage especially in the spring on the young new growth. Castlewellan grows slightly slower than the Green Leylandii but still forms a dense evergreen hedge quickly.

Castlewellan will grow in sun or partial shade although its best gold colour is produced in full sun. It is very hardy and wind tolerant so will grow in exposed sites.

Plant between 60 and 100cm apart (2-3ft) apart.  If you want the hedge to “fill-in” and form a dense screen quickly, then plant 60cm (2ft) apart, if you are willing to wait a bit longer, then plant at 100cm (3ft) apart as you will get just as good a hedge, it will just take a bit longer.  However, if you intend to grow the hedge more than 4m (12ft) tall, do not plant them closer than 100cm (3ft apart). 

Keep Leylandii Castlewellan Gold regularly trimmed (once a year) and it can be kept at any height and any width and will form a dense hedge. If it is left untrimmed, it will grow more than 25 metres.

The growth rate of Leylandii Castlewellan Gold is up to 80cm (2’6”) per year.
