Leylandii Hedging


Planting a 9ft Leylandii hedge is a very quick option to achieving a large hedge fast. These plants are extremely bushy, all are 8-9ft (240-270cm) in height and will form a thick hedge immediately after planting. The height and bushiness of these plants means they represent good value for money for a hedge of this size. A 9ft leylandii hedge is often more the high enough for most gardens and these plants can be planted and trimmed down slightly to give a slightly lower hedge but a much more instant looking hedge.

Leylandii are a fast growing evergreen and these plants will put on 2-3ft (60-90cm) each year if left untrimmed and so it will not take long for these plants to produce a Leylandii hedge at the required height to give eye level privacy.

Once the plants have reached their desired height, we recommend that it be trimmed at that height which will both encourage side growth and restrict upward growth to a manageable amount. A leylandii hedge needs to be trimmed annually in the spring or autumn.

Any leylandii hedge plants should be planted 2ft (60cm) apart and if they are planted during the drier summer months, they must be properly watered in their first year to ensure that they establish properly. This is best done using leaky hose which is cheap, easy to install and very effective.

Cupressocyparis leylandii Hedge Plants Description

Leylandii must keep a maintainable height; it has a bad reputation if this isn’t achieved. Fortunately, Hedges Direct has advice available on our website to support, and you can call our team if you have any questions on 01257 263 873. Leylandii is still a popular choice of hedge plant amongst those who recognise its superb attributes and looking for a good hedge height on a small budget. Regular clipping of the mid-green, spray like citrus-scented foliage during midsummer and autumn, can turn Cupressocyparis leylandii into a magnificent, dense, formal garden hedge that is perfect for windbreak and noise reduction.

Hedges Direct also has Golden Leylandii available to buy online. Golden Leylandii is a brightly coloured hedging conifer that makes a fantastic alternative to the traditional Leylandii hedging. Read our conifer hedging guide for more information on this type of species.

If you are looking for a similar conifer appearance to Cupressocyparis leylandii that can be cut back into old wood, please consider Western Red Cedar. Alternatively you can view our range of conifer hedging plants here. If conifers aren’t suitable for your garden type, Hedges Direct offers a wide range of evergreen plants and hedging.

In addition we also have a stunning range of beautifully scented fragrant hedging plants available plus shrubs suitable for exposed sites – ideal for those seaside gardeners.

Extra Tall Root Balls – Minimum Order Quantity and Delivery

Please note that there is a minimum order requirement of 5 plants for the extra tall root balls due to the specialised delivery required. Because of their extreme size and weight, these hedging plants need to be transported via articulated lorry and require a forklift to remove from the truck and into place for planting. A forklift icon on the listings indicates these products.

In 1888 something very rare happened on a country estate in Wales: a plant genus was born. Ever since, it has been nothing but trouble. It has caused civil unrest, violence and even murder in its march across the country. Until recently it was the bestselling plant in every garden centre in Britain. As with rats, wherever you are, you’re never far from a Leyland cypress.

Its full name is x Cuprocyparis leylandii, which translates as “tree most likely to annoy your neighbours”. It was discovered on the 4,000-acre Leighton Hall estate, near Powys, after a Monterey cypress and a Nootka cypress – which in nature grow nowhere near one another – cross-fertilised and produced six seedlings. The new tree has become so infamous that it’s known by only one name.

Leylandii’s success is especially impressive when you consider that it can’t reproduce, which means that every plant we see today comes from cuttings and has been planted by humans. How did such a mundane tree become so popular? Because it’s evergreen and vigorous. A leylandii will grow three feet every year, so in no time at all you’ll have factor 50-style privacy, something our insular society finds irresistible. The trouble is, it won’t stop: the tallest one is already 40 metres (130ft) and still growing.

Live with it…

So what do you do if you have them (there’s usually more than one) in your garden or, worse, a neighbouring garden? Management is crucial: this is not a plant you can turn your back on, especially when it comes to the soil. While deciduous trees will enrich the soil with organic matter in the form of fallen leaves, leylandii will treat it like a student treats a bank account – it’s all take, take, take. Before long your soil will have turned to dust. You’ll need to compensate by heaping on leaf mould, garden compost or rotted manure in autumn and spring.

Any nearby plants will also have to contend with leylandii’s dense canopy. Fortunately, there are some that can tolerate dry soil and aren’t afraid of the dark. The most fearless of all is Mrs Robb’s bonnet (Euphorbia amygdaloides var robbiae). This evergreen ground cover plant looks far too pretty to be such a trouper, but plant it around the outskirts of the leylandii and it will soon spread where the sun don’t shine. So will Siberian bugloss (Brunnera macrophylla ‘Jack Frost’). This is not evergreen, but its delicate blue flowers, similar to a forget-me-not’s, more than make up for that.

For something taller you could try bear’s breeches (Acanthus spinosus). This tough perennial will produce flower spikes a metre high and its leaves will cover at least a square metre. For a splash of leaf colour, there’s the purple-and-white-foliaged Heuchera ‘Regina’. In the spring this clump-forming perennial produces flowers that are both good for cutting and attractive to bees.

If you want something complementary, try Cotoneaster lacteus. This evergreen shrub is a strong grower and, at three to four metres high, is tall enough to hold its own. Growing it in front of leylandii will show off its bright red autumn berries, too. Evergreen Mahonia aquifolium and Mahonia x media ‘Charity’ are smaller at 1.5 metres but will produce cheerful, fragrant yellow flowers in winter.

…or get rid of it

But what if the leylandii is in the garden next door? Any overhanging branches can legally be cut back to the boundary line. This goes for roots, too, and whoever owns the land the tree is growing on may be liable if it causes damage. In 2005, new legislation meant local councils could force owners of nuisance hedges more than 2m tall to reduce their height (visit rhs.org.uk for information about how to complain about a hedge). But it’s the parts you can’t see you should worry about. Leylandii roots extract so much water that they can cause clay soil to shrink, leading to subsidence in buildings.

Simply felling the culprit isn’t always the solution. If the tree has been taking out significant amounts of water, removing it may cause the soil to rehydrate and swell. This “heave” can be just as damaging. A large tree should be cut down in stages, which allows the soil to adjust. Some insurance companies ask if there are any trees taller than 10 metres growing within five metres of your property. If it’s a leylandii, your premium could be higher.

Cutting back overhanging branches shouldn’t be left too long, either. If you cut back too much in one go, it won’t regrow and you’ll be left with a brown patch. Simon Richmond, technical officer at the Arboricultural Association, says the key to pruning leylandii is little and often. He recommends pruning them twice a year once established, in late spring and again in late summer.

He also warns of the disease Kabatina shoot blight, which causes brown patches. “Sometimes the tree will recover if you feed and water it – but sometimes the only thing you can do is remove it, which isn’t ideal if it’s in the middle of a hedge.”

If you’d prefer a better-behaved evergreen screen, try holm oak (Quercus ilex), a broadleaf tree that responds better to close pruning. If it’s a conifer you’re after, try Thuja plicata or Chamaecyparis lawsoniana ‘Pembury Blue’. My favorite conifer, however, is yew (Taxus baccata); this slow-growing tree is proof that good things come to those who wait.

Most species of conifer are evergreen, but there are a few deciduous varieties. Some varieties of conifer are good for privacy, as they make excellent hedges. Some are also good for ground cover. They usually have scale-like leaves or needles, and bear iconic cones.

Planting and Conditions

Conifers can be planted throughout the year, but it is best to plant them in the late autumn or winter, as long as the ground is not frozen or waterlogged. Most conifers are frost proof to an extent and hardy, so they will be able to establish well throughout cooler weather.

They should be planted in full sun or partial shade, and are tolerant of most soil types, but will benefit from having compost or manure tilled into the soil prior to planting.

Conifers also need decent draining, so do not plant them in very heavy clay soil or else you will risk drowning the plant.

A hole no less than 1m across and 25cm deep should be dug when planting your conifer. Add organic material such as compost or manure to the hole, and fill it in carefully so that you don’t damage the roots.

Aftercare and Pruning

Unlike other hardwood plants, conifers need very little pruning. However, if green branches appear in trees with coloured or variegated foliage, these should be pruned more often.

Dwarf conifers are not actually dwarf, but are just slower growing. They will eventually become larger and could outgrow their space. This is fairly common with most conifers as they grow, and they can be replaced when it happens. However, their size can be controlled to some extent by pruning and trimming them.

A few conifers such as yew and Thuja, can be pruned hard and will regrow. Most conifers will not regrow from old wood if you prune into it, so take care.

Conifers can be pruned from spring through to late summer.

Newly planted conifers need very careful watering during the initial stages. They are drought proof once established and should not need too much watering, but they are very vulnerable to stress from drought if they are not watered thoroughly.

Removing weeds as soon as they appear is a good way of ensuring that valuable moisture is not lost. Mulching also reduces moisture loss from the top layers of soil.

Potential Issues

Plants can suffer from nutrient deficiencies. Overly acidic or alkaline conditions, dry spells and waterlogging can make it very difficult for plants to extract the right nutrients, and sometimes the soil doesn’t have the right nutrients to start with.

Depending on which nutrient is deficient, mulching, using compost or using a spray enriched with the right nutrients is the remedy to this common ailment.

Brown patches may occur on conifers. There are a number of causes; pests such as the cypress aphid and scale insects can be treated with sprays and foliage removal. Parasitic wasps can also be brought into greenhouses as a biological control for removal of scale insects.

Establishment problems can also occur in young or newly planted conifers. Larger specimens will experience more problems establishing, and will require much greater aftercare than younger specimens. Watering the plant well, but not excessively, and not planting it too deeply should help it to establish better.

Never spray with fertilizer or feed during hot, bright weather or you will risk scorching the leaves. Spray in overcast weather instead.

Root rot can occur when the plant is getting too much water. To remedy this, increase drainage around the plant.

Honey fungus could also occur as a result of waterlogging, or if it is already present on the plant or in the garden. It is the most destructive fungus in Britain, and unfortunately the only treatment is evacuation and burning of affected plant material.

Be sure to extract stumps and roots, as the rhizomorphs that grow during a honey fungus infestation cannot survive in soil when detached from infected material.

Leylandii Hedging

You can save money over winter by planting ROOTBALLS

With over 300,000 leylandii hedge plants sold each year, making it by far and away the most popular hedging plant in the UK, leylandii hedging is a staple of landscape gardens up and down the country. This fast growing evergreen conifer is characterised by its flattened sprays of greyish-green foliage and its upward-curving branches. Leylandii truly does have the ability to enhance the look of any outdoor space.

Aside from their beautiful aesthetics, leylandii hedge plants can also be used as a functional living boundary capable of providing privacy and shelter to your garden. Although semi-regular maintenance is essential when it comes to leylandii, these versatile and practical plants can be used as an effective windbreak – offering shelter to more exposed landscapes – while also suppressing noise levels from nearby properties and neighbouring roads. So, whether you live in a busy urban area or in a rural landscape open to the elements, leylandii hedging is a practical and attractive choice you might want to consider.

Choosing the right leylandii for your garden

Here at Grasslands, we have a broad range of hedging for sale. We offer a selection of leylandii plants in a number of colours, shapes and sizes. This includes everything from our ever popular three litre pots of castlewellan gold with their beautiful and incredibly dense golden-yellow foliage to our much larger 55 litre pots of green leylandii hedging – our fastest growing variety which is capable of developing into effective screen hedging almost instantly.

All of our pots are ready for immediate planting upon purchase – all you need to have ready is the space in your garden! This quick and easy method of planting means our leylandii can be used by gardeners of any level or ability. So, regardless of whether you are a greenfingered pro or a landscaping novice, you certainly won’t struggle to find the right leylandii plant to perfectly complement the look of your garden in our wide range of options.

Caring for your leylandii hedge

Leylandii hedge plants are highly versatile and will typically tolerate most soil types, including clay, chalk, sandy and loamy soils. They grow best in full view of the sun or in partial shade, and can even develop well in exposed windy landscapes and coastal locations.

The fastest growing conifer in the UK, leylandii will regularly grow up to 3ft per year and can reach breathtaking heights of 130ft if left completely untrimmed. Thanks to the superfast nature of its growth, when it comes to pruning, leylandii will need a serious trim at least once a year. However, we recommend cutting your leylandii hedge two or three times a year – ideally in spring and summer. Upon planting a new leylandii, it is important to only prune your hedge once it has reached your desired height. This will ensure the hedge maintains a nice shape and encourages outward growth to improved density.

Leylandii Castlewellan Gold

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.

Why plant a Leylandii Castlewellan Gold hedge?

Grows in any soil (except waterlogged)
Acts as a great windbreak
Filters out air pollution

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 (-25⁰C) 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 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). For more information, see our Hedge Spacing Calculator.

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.

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 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.
