Leylandii Castlewellan Gold

Where will Leylandii Castlewellan Gold grow?

Castlewellan will grow in sun or partial shade although its best gold colour is produced in full sun. It is very hardy (−25°C) and wind tolerant so will grow in exposed sites. Although it will take some salt exposure, it should not be planted right next to the sea.

What type of soil does a Castlewellan hedge need?

Castlewellan will grow in any soil as long as it is not waterlogged.

How tall will Leylandii Castlewellan Gold grow?

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 (75ft) tall.

Why plant a Leylandii Castlewellan Gold hedge?

  • Quick-growing
  • Evergreen
  • Hardy
  • Grows in any soil (except waterlogged)
  • Acts as a great windbreak
  • Filters out air pollution

How often would I need to trim/prune a Leylandii Castlewellan Gold hedge?

All evergreen hedges, including Castlewellan hedges, need to be trimmed once a year to keep them to the height and width you want.

How fast will a Castlewellan hedge grow?

The growth rate of Leylandii Castlewellan Gold is up to 80cm (2’6”) per year.  It is slightly slower growing than the green form of Leylandii but it is still one of the quickest evergreen hedging plants.

How far apart should I plant Leylandii Castlewellan Gold?

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).
