Castlewellan Gold Hedging

Castlewellan Gold Hedging

Castlewellan Gold is the golden version of Leylandii and makes an excellent hedge which keeps its golden yellow colour all year round. Like Leylandii, it is quick growing and is the best of the golden hedges but requires full sunlight to keep its colour good. Castlewellan Gold hedges respond well to annual clipping and it is best to clip early Spring or early Autumn just before a new flush of growth to show the best of its colour. Regular clipping will encourage a dense and tight hedge which will act as an excellent visual barrier as well as absorbing much noise and pollution.

Why should I plant a Castlewellan Gold hedge? 

Castlewellan Gold is otherwise known as Golden Leylandii and has been a popular Leylandii alternative for many years for those wishing to create a hedge that performs as well as Leylandii but prefer a golden/yellow colour rather than the standard green of Leylandii.  Castlewellan Gold is fast growing, evergreen and produces a dense hedge in a short period of time.

How tall will Castlewellan Gold grow?

People often ask how tall Castlewellan Gold or Leylandii will grow and the simple answer is that they will grow as tall as you want them to.  They will produce an excellent hedge of any height from 5-20ft, although most people tend to grow their Castlewellan Gold hedges to 6-7ft in height which is usually more than adequate for most gardens.

How quickly will a Castlewellan Gold hedge grow?

Castlewellan Gold do grow fast after they have been planted and can put on 2ft growth a year in their first few years after planting.  This is marginally slower than standard green leylandii.  However, once the hedge has reached its desired height it should be trimmed at that height accordingly to maintain its size and density.  This will slow down the upward growth of your hedge to a much more manageable level meaning it can easily be trimmed once a year.  We hear reports of leylandii hedges getting out of control and in almost all cases, this is as a result of the owner neglecting the hedge and not managing it properly, it is not the fault of the plants themselves.

When should I clip or trim a Castlewellan Gold hedge?

A Castlewellan Gold hedge will need to be clipped annually in the Spring or Autumn as you would with any other hedge.  A clipping in the early Spring just before a flush of new growth will ensure that the hedge shows off the best of its golden yellow colour.

How far apart should I plant a Castlewellan Gold hedge? 

Castlewellan Gold should be planted 2ft (60cm) apart regardless of how tall or short they are when you buy them and careful preparation of the planting site is important.  See section below on how to look after your leylandii hedge after planting.

How do I look after my Castlewellan Gold hedge after planting?

Although Castlewellan Gold plants will put up with most soil types, we recommended that the planting soil is mixed with compost to give the plants the best environment to grow in for their first year.  After planting, your Castlewellan Gold hedge should be watered regularly during its first year to give it the best chance of survival and this is especially important if your hedge is being planted in the drier summer months.

How do I water my Castlewellan Gold hedge?

Watering a Castlewellan Gold hedge is especially important if you are planting during the summer or a dry period.  For watering, we recommend using leaky hose (sometimes described as porous pipe) which can be connected to your existing hose pipe and will slowly leak water onto the roots of your hedge in a controlled manner to ensure that it soaks in and your hedge becomes properly watered.  Leaky hose is cheap, easy to install and very effective.  See our Accessories page for more details on leaky hose.

Is Castlewellan Gold tolerant of different soil types?

Castlewellan Gold will tolerate most soil types (including dry sites) but do not like being in waterlogged soil. 

Does leylandii like full sun or shade?

Castlewellan Gold grow extremely well in full sunshine and they do require full sunshine in order to bring out the best of their golden yellow colour.  They do not like growing in shady spots and don’t grow well under the other trees.

We usually stock a selection of different sizes of Castlewellan Gold throughout the year.
