Privacy is something we must respect. You wouldn’t want the neighbors taking a peek at your shenanigans.

Instead of going for a bland and dark privacy fence, why not electrify the home with eco-friendly trees, plants, and evergreens.

Let’s familiarize ourselves with the best trees for privacy, shall we?

What Are the 9 Best Trees for Privacy?

With so many trees and shrubs, it may be hard to pinpoint the differences and advantages one tree has over the other.

Thankfully, we narrowed down our picks to help you and your fellow homeowners have an easier time making your choice.  Regardless of what tree you pick, do know that you are in good hands.

These trees offer respectable height and width dimensions that shield your home from natural disasters and disruptive neighbors. 

Leyland Cypress

Need tall trees to cover up the backyard? The Leyland Cypress does just that and then some.

For starters, these evergreens are considered fast-growing privacy trees because of their exponential development in height.

Measuring 50 feet in height and 10 feet in width, Leyland Cypress gives your yard much-needed tranquility from the hustle and bustle of city life.

If you plant these low-maintenance evergreen trees in 8 to 10-foot tall centers, you get reliable privacy screens that combat noise pollution, wind, and snow.

“How can I get these benefits all year round?” you may be asking.

For the Leyland Cypress to maintain a steady growth rate, expose them in full sun for 6 hours straight.

FUN FACT: The evergreen tree can be used as a fence for those living by the shore because of its high resistance to salt.

Eastern White Pine

Are you feeling overwhelmed that “Winter is Coming”? Why not try out the Eastern White Pine.

While the typical evergreen tree loses its green leaves from December to February, The White Pine plants withstand extreme winter conditions.

You heard that right. Winter pines remain intact in areas with temperatures of up to -40 degrees Fahrenheit.  

For the best results, set up the 60 feet tall and 30 feet wide plants in open spaces and massive landscapes.

By doing so, you maximize the allotted space and declutter the expansive view of the outside world.

If you are the photogenic type, their delicate leaves and straight branches make a good background for your next Instagram picture.

Concolor Fir

Need more suggestions to get your yard ready for the winter season? Enter the Concolor Fir, another prominent privacy tree.

One unique feature the tree has over its counterparts is its silver, blue, and deep green foliage. Expect a colorful and creative privacy screen should you go with the multicolored evergreen.

Similar to the winter pines, concolor firs are immune to -40 degree Fahrenheit conditions. I encourage you to stack up on these evergreens as soon as possible in time for the winter months. 

Unfortunately, the evergreen plant works best in cold areas only. So if you live in the tropics, I suggest you skip this part.

You also have to make sure the concolor firs are not exposed to city pollution and poor soil conditions. These may spell the difference between a tree that grows moderately or wilts.

Green Giant Thuja (Arborvitae)

The Arborvitae Green Giant has your house fully covered from other property lines and rowdy neighbors. 

Indeed, the evergreen plant lives up to its name thanks to a massive height range of 30 to 40 feet.

Unlike other evergreens, the arborvitae offers maximum protection from varying weather patterns. It can survive the hottest summers and coldest winters.

You can also clump arborvitae leaves together to produce healthy green foliage. Planting them at around 5 to 6 feet in the center will result in a low-maintenance and functional living fence.

Just be sure to expose the Green Giant evergreens under the full sun for around 3 to 6 hours so that they grow at a mature height. 

Do you need a break from the dangling power lines and messy sidewalks?

What better way to end the day than coming home to Green Giant Arborvitae privacy screens, trees, and shrubs?

Japanese Cedar

Let’s start with a fun fact. So you may be thinking that the Japanese Cedar is similar to other privacy trees in terms of features.

However, what if I told you that the East Asian plant lasts up to 600 years? That’s six centuries of top-tier quality and resistance to extreme weather.

Dimensions-wise, it outdoes the rest. It boasts a superior height range of 50 to 70 feet and a moderate width of 20 feet. [R]

With these dimensions, Japanese cedar trees and shrubs guarantee the utmost protection and privacy for your yard.

To get the best results all year round, plant these evergreens in well-drained soil. Also, they operate better when given full sun exposure.

If you want your house to undergo a full Japanese makeover, I suggest placing the cedars in a screen or privacy fence made out of bamboo. 

Sky Pencil Holly

As you continue reading the best trees for privacy, I am sure the primary concern you and most homeowners have is the amount of space trees and shrubs take up.

Luckily, the Sky Pencil Holly gives you a balance of maintaining your privacy while minimizing used up space.

The plant height ranges between 8 feet and 10 feet.  A 2-foot width ensures that the yard is not filled up with too many shrubs and foliage.

I know what you may be thinking. “These dimensions are the smallest among the featured privacy trees.”

Despite the small height and width, Sky Pencil Hollies still deliver ample protection and support against strong winds, outside noise, and peeking eyeballs.

Therefore, you have nothing to worry about with regards to your privacy being invaded.

American Holly

The American Holly is a staple privacy tree among many households, backyards, and hardiness zones all across the US.

Missouri, Massachusetts, Florida, and Texas are some of the states that house the US native plant.

Once it reaches the final stages of maturity, it goes for 50 feet in height and 20 feet in width. That is equivalent to around 7 to 8 football fields.  

Besides being a premier privacy tree, it is also one of the best fruit trees. That is because red berries grow during the fall season.

While most trees and plants require full sun exposure, the American holly works best with minimal lighting.

Weeping Podocarpus

Hailing from the California and Florida backyards, the Weeping Podocarpus is another popular choice among many homeowners and residents.

While most privacy screens have rough edges, this particular tree contains soft billowing foliage.

Therefore, you won’t have to worry about getting scars and wounds for accidentally leaning on your privacy screen. 

These trees are most suitable for coastal areas due to their high salt tolerance. They can also withstand significant droughts and heatwaves.

For those living in scorching hot areas, this is the privacy tree for you.

For Weeping Podocarpus plants to survive all year round, fertilize these with granules thrice a year. Nothing more, nothing less.

It also pays to provide ample water supply in case dry spells or water shortages take place.

Goldspire Ginko

You can’t go wrong with decorating the backyard with hints of gold. The Goldspire Ginko incorporates green and gold colors depending on the season.

On the one hand, green tones surround the trees during the summertime. However, once the fall season starts kicking in, expect gold leaves all over the privacy plant.

An advantage it has over its privacy tree counterparts is its ability to resist smog.

If the 14 to 16 feet tall plant can withstand a toxic version of fog, it can definitely handle unusual weather patterns and extreme conditions.

With proper exposure to sunlight and moderate watering of the tree, you have yourself a privacy screen that fits a medium-sized yard.

What Are the Different Arrangements of the Best Trees for Privacy?

With so many privacy trees and plants at your full disposal, it can get tricky to find a proper plant arrangement for your backyard.

Fear not, for we will go over the different tree setups you can try out at home. Here are some ways you can arrange your plants and trees for a more vibrant privacy screen.

Same Plant Type

Want a minimalist backyard? If yes, you can try planting multiple trees of the same variation all over your garden.

The arrangement’s consistency and uniformity will have a lot of eyes glued to your yard.

Unfortunately, the single plant type setup is the most high-maintenance and difficult to handle.

One underperforming tree may spell the difference between a good-looking fence and an uneven privacy screen. 

Using this arrangement will take up a lot of time for perfectionists because every tree has to be pruned and assembled evenly.

If you have the means to maintain the single tree setup, then go for it by all means. If not, we suggest that you continue reading for better alternatives.

Assorted Plantings

Another reliable option is mixing up the yard with multiple shrubs, plants, and trees.

Visually speaking, the combination of different plant varieties will catch most homeowners, guests, and neighbors’ attention.

If you are craving a creative touch to the home, you should consider applying this arrangement method.

It is also easy to maintain in the long-run. You won’t have to worry about differing plant sizes and required sunlight for each tree type.

In the single plant type, including a different tree variation feels like having a pimple on the face.

Simply put, they complement one another in terms of aesthetics and performance level.

What Are Some Tips for Planting Best Privacy Trees?

With many privacy tree varieties at your disposal, assembling the best privacy screen setup can be a daunting task.

Questions such as “Which trees should I choose?”; “What dimensions should I apply?”; and “How do I plant privacy trees?” may come to mind.

Fortunately, this part of the review tackles the different tips you can follow when setting up that privacy screen for your yard.

Diversify the Yard

The first tip is something I cannot stress enough. You need to make sure you supply your backyard with different plants and trees.

Sticking with one plant or tree variation may be detrimental for the garden. Why is that the case?

For example, you decide to fill up your privacy fence with Eastern White Pines only.

Sure, it gives you high-quality performance in terms of maintaining your privacy. However, that won’t be the case anymore once the winter season comes to an end.

What if the backyard is full of Leyland Cypress? They may be great at blocking out noise pollution, but pests and worms may start creeping on the soil as time goes by.

In short, choose different plant varieties for a more enhanced and well-protected privacy fence. A range of 3-5 shrubs and plant varieties should do the trick. 

Space Out Your Trees and Plants

For you to maximize the benefits and advantages of each plant type, evenly space them out.

Although privacy plants and trees are supposed to produce natural privacy fences, clumping the plants may not allow everyone to have equal sun exposure.

As a result, fungi and bacteria develop due to the lack of sunlight and air ventilation.

What does this mean for your privacy screen? Simple. It will disintegrate and rot in the long run because the clumped plants transfer diseases to one another.

If you really are a fan of grouping the shrubs and trees altogether, organize these into groups of 3-5 layers.

Not only do you still get your much-needed privacy, but you allow each plant to receive equal sunlight and air circulation.

Take Note of Your Location’s Weather Conditions

Not everyone lives in the same geographical location. What does this mean?

You may be living on a hot and tropical island, but your nearest relative might reside in winter-friendly places.

Therefore, it is essential to do prior research about the plants and trees you plan to buy.

You may like the Goldspire Ginko because of its aesthetics, but what if your country experiences summer all year round.

You won’t be able to enjoy the gold leaves that emerge in other areas with a fall season.

Select Proper Dimensions

Not all houses are uniform in size. Some households have bigger backyards, while others not so much.

So before securing your privacy screen, be sure to have a grasp of your house’s dimensions.

If you have a medium-sized backyard, a 20-30 feet tall and 10-15 feet wide screen should be enough.

You also have to take into account the fact that you are living with other neighbors and homeowners.

I am sure your neighborhood has specific community guidelines and zoning rules to follow. As a good neighbor, choose plants that preserve your privacy and satisfy property ordinances.

Ask Feedback From Other Neighbors, Homeowners, and Experts

When in doubt, it pays to seek help from others. We all do not have definitive answers to everything, and that’s totally fine.

This is why asking for other people’s experiences won’t hurt at all.

Although one’s plant choice may differ from another, getting mixed reviews and personal anecdotes from neighbors can go a long way.

Of course, getting scientific facts helps a lot. The more data you have, the better. 

Doing your research and asking for input from experts give you essential information like growth rate, seasonal changes, tree dimensions, plant behaviors, etc.

Think Long-term

During the selection process, always have a long-term approach. Remember that you are looking for the best trees that will keep your house safe and secure for years to come.

Due to the unpredictability of time, you cannot predict storms, natural disasters, and intruders.

Therefore, it should be your top priority to guard the home with stable, well-rounded, and environmentally-friendly plants.

If anything, not only do you keep your privacy sacred, but you also do your part in our long-term goal of saving the environment.

That’s not a bad way to make both ends meet.

Conclusion

I hope you enjoyed going over the best trees for privacy. Regardless of what you choose, these fast-growing plants and evergreens guarantee maximum protection for your backyard. 

I also entrust that you have thoroughly gone over the different guidelines and conditions of setting up your privacy screen.

We may have laid out all the facts, tips, and tricks, but it’s still your choice at the end of the day. May you pick plants and trees that satisfy your personal preference and household needs.

WHAT TO PLANT INSTEAD OF LEYLAND CYPRESS…AND WHY

What to Plant instead of Leyland Cypress…and Why

Leyland Cypress

Leyland Cypress (Cupressocyparis leylandii) is a popular choice for a hedge to provide privacy and wind protection due to its extremely fast growth rate. Leyland Cypress Trees is noted for its fastest screening tree for privacy. The Leyland Cypress is widely used in the USA. However, many people who plant Leyland Cypress without knowing all the potential problems find themselves in a big pickle a few years later and ruing the day they planted the pesky trees. Here we have collected all the reasons not to plant a Leyland Cypress hedge, as well as the best leyland cypress alternative.

Reasons people like Leyland Cypress

Leyland Cypress Growth Rate is the main reason people choose to plant Leyland Cypress. No one likes to wait, and the idea of buying small, inexpensive plants that will grow to huge trees in just a few years is very appealing. The problem is that most people fail to think farther than those first few years and anticipate the enormous eventual size of the plants (they don’t stop growing, folks!).

Evergreen foliage of Leyland Cypress is a big factor when choosing a privacy hedging plant, and also Leyland Cypress has a nice-looking, feathery, evergreen texture.

Large size of Leyland Cypress is good when you need privacy, but the tree can get absolutely massive (anyone wants a 75’ tall hedge?). Most privacy hedges are sufficient at 6-10 feet tall, and much easier to maintain.

Leyland Cypress Problems

Can anyone suggest to me a fast growing tree that provides a lot of privacy like a Leyland Cypress (except not a Leyland Cypress)? Sounds familiar statement for Leyland Cypress right?

Leyland Cypress problems are common these days, Leyland Cypress growth rate is the main thing that draws people to Leyland Cypress, but it is also the biggest problem in the long run. Leyland Cypress grows extremely fast, up to 4’ per year, even in poor soils. That sounds great when you think you could have your goal 12’ privacy hedge in 3 years, but think about how much you will have to prune it to keep it at 12’ tall in the long run. Hint: it’s a lot.

You will need to prune intensively multiple times per year to maintain the size and shape of Leyland Cypress. The larger it gets, the more difficult it will be to prune. You also have to be careful about what time of year you prune, as pruning in early spring may simply encourage faster growth, but pruning in the fall or winter can cause unsightly browning. If the size gets out of hand, you can’t prune it back too far or you will be left with ugly brown patches that never fill in.

Once the Leyland Cypress reaches large height and width, you will likely run into problems with foundations, sidewalks, and power lines, and eventually end up needing to remove the plants.

Leyland Cypress leyland cypress trees

Leyland Cypress growth rate – the first photo is from October 2012, the second is from August 2018. The trees have grown about 12’ taller and significantly wider in 6 years in a spot with likely no supplemental water. Imagine how much faster they would grow in a normal garden setting!

Leyland Cypress diseases are another factor to consider. Their root systems are quite shallow, and any stress on the plants weakens them to some common diseases, including blight, canker, and root rot. When planted as a hedge, the diseases can run right through the plants, damaging or killing the entire row. Once the plants are infected, fungicides and other chemicals are ineffective for treatment.

Hedging is not simply compatible with Leyland Cypress’s growth requirements. They don’t grow well in crowded conditions. They are notorious for developing somewhat random brown patches and sustaining winter damage, which results in an uneven, unsightly hedge. They are shallow-rooted and unstable in the soil. They have no drought tolerance, but excessively wet conditions result in root-rot. Finally, they are short-lived plants, usually lasting only up to 25 years before needing to be replaced. None of these are good conditions for hedging!

Leyland Cypress Alternative

  • leyland cypress vs arborvitae

    Green Giant Arborvitae is the best fast-growing Leyland Cypress alternative. It is essentially disease-free, with moderate drought resistance and excellent tolerance of heat and humidity. It can grow up to 3 feet per year and can be maintained with 1 or 2 pruning sessions per year. It is hardy in zones 5-9 and can be grown in full sun to partial shade.

  • Leyland Cypress Alternative

    Virescens Western Red Cedar is another great alternative for Leyland Cypress, with a nice, upright growth habit. It can either be tightly pruned for a formal look or causally pruned for more relaxed garden styles. It can grow up to 2 feet per year which is less than Leyland Cypress growth rate. It has moderate drought tolerance and can be grown in full sun to partial shade. Virescens is hardy in USDA zones 5-9 and does especially well on the West Coast, where it is native.

  • leyland cypress alternative

    American Arborvitae is an extremely cold-hardy Leyland Cypress alternative, growing in USDA zones 2-8. It is native to the Eastern United States and Canada, and has been a popular hedge choice for many years. It can grow 1-2’ per year and thrives in both full sun and partial shade. It responds very well to regular pruning and is very low-maintenance than Leyland Cypress. American Arborvitae has moderate drought resistance.

How To Grow Leyland Cypress Trees

Leyland cypress (× Cuprocyparis leylandii) is a fertile hybrid cross between Monterey cypress (Cupressus macrocarpa) and nootka false cypress (Chamaecyparis nootkatensis). It is a fast-growing evergreen conifer (18 to 36 inches per year in early years) with a dense, broad-columnar to narrow-pyramidal habit. It typically grows as a tree to 60 to 70 feet tall unless it is kept pruned as a hedge or specimen shrub. From its nootka false cypress parent, it inherits its habit, foliage, and winter hardiness, and from its Monterey cypress parent, it inherits its branching pattern and rapid growth. Leyland cypress has flattened sprays of gray-green foliage on slender upright branches, and dark brown fruiting cones, 3/4 inch across with eight scales. The scaly bark is reddish-brown.

Leyland cypress trees will give you fast growth if you are looking for a privacy screen or a Christmas tree for your yard. For best results, plant the trees when they are dormant in the fall, about six weeks before the first frost. They are tolerant of pruning, but be prepared to prune often if you want to maintain a certain size or shape.

Leyland Cypress Tree Care

Leyland cypress trees are generally grown to meet an urgent need for a mass of evergreen foliage to create a privacy hedge. Height can vary greatly, depending on the variety and the conditions in which you grow them. For best growth, plant in a full sun site with evenly moist fertilized soil. The average height for an untrimmed Leyland cypress is about 50 feet, but do not be surprised if yours grows much higher or much shorter than that. Taller than they are wide, the spread of this columnar tree is commonly only one-third or one-fourth of the height, sometimes less.

A common landscape use is planting several Leyland cypresses along a border, in order to create a privacy screen. They are also used as windbreak trees. Since they are amenable to shearing or pruning, some homeowners take this a step further and turn such a border planting into a formal hedge.

Be sure to prune them early and often; otherwise, due to their fast growth rate, they tend to get too tall too quickly and can overwhelm a landscape. In addition to these practical landscaping uses, these plants are frequently used as Christmas trees.

Light

While Leyland cypress is forgiving of most light conditions, it does not tolerate shade well. It grows best in open, sunny conditions or partially shaded areas.

Soil

Although it prefers a moist, fertile, well-drained soil, this tree tolerates a wide range of soil types—clay, loam, or sand and acidic or alkaline.

Water

The tree tolerates occasional drought or brief waterlogging. To help its roots get established after spring or summer planting, water your Leyland cypress regularly. A Leyland cypress will take a few months to get established. After that, apply one gallon a week to the rootball if you live in USDA zones 7 or 8, and two gallons a week if you live in USDA zones 9 or 10. For the first and second years, water your Leyland cypress twice a week through spring and weekly in summer, tapering off to once to twice a month in winter. The older the tree, the longer you can go between waterings. Use soaker hoses, not sprinklers that will wet the foliage.

Temperature and Humidity

Leyland cypress trees are best grown in USDA hardiness zones 6 to 10, with temperatures no lower than -8 degrees Fahrenheit. However, zone-5 gardeners have been successfully growing them by providing mulch and an A-frame shelter in the winter months to protect them from snow and ice damage. Such sheltering is feasible only while the plants are young—unless you keep them short by pruning. Luckily, once the plants have matured, sheltering becomes unnecessary, as they will prove to be sufficiently cold-hardy in zone 5.

Fertilizer

Fertilize Leyland cypress in early spring, before new growth begins. Spread a general-purpose, 10-10-10 fertilizer around the tree's drip line.

Leyland Cypress Varieties

There are many cultivars of Leyland cypress that are identified by the color of their foliage:

  • 'Leighton Green' is commonly used as Christmas trees. Its dark, forest-green foliage makes it ideal for holiday decorating. Heavy and stout, this cultivar has a coarser appearance than other varieties.
  • 'Silver Dust' has a leaf structure similar to 'Leighton Green' but with white variegated splotches on the foliage.
  • 'Naylor's Blue' is known for its attractive blue-gray foliage. It grows to up to 60 feet tall and 10 to 15 feet wide. The scaled needles vary in color depending on the season. In winter it takes on a ghostly grey hue.
  • 'Castlewellan' tends to grow in a conical shape. Its delicate, lacy foliage is a favorite feature. In the winter, the tree's exterior turns a gold hue while the interior remains green.

Pruning Leyland Cypress

The height of a Leyland cypress can be controlled (you can grow them as multi-stemmed shrubs), but only through persistent pruning that starts when the plants are young. Trim the sides of Leyland cypress trees every year in July. After the leader has reached the height you want the tree to retain, make a pruning cut a few inches below that (which will leave room for the vertical growth of minor branches) to preclude any further significant upward growth, as you would do when pollarding a tree.

Propagating Leyland Cypress

Since the tree is a hybrid, the Leyland cypress is almost always sterile and propagated mainly from cuttings. Successful rooting is achieved most often with cuttings taken from trees less than 10 years old, or from new shoot growth on older trees. January, February, or March are the best months to do the cutting. Cuttings should be 6 to 8 inches long and show some brown coloration in the lower part of the stem.

Dip the end of the stem in a rooting hormone used for woody trees. Plant into a porous planting media. Maintain the cutting in a warm, humid environment. Once the plant develops roots, transplant into a gallon-sized container. After six to nine months, the plant should be ready for planting outside in the spring.

Common Pests/Diseases

Leyland cypress trees are shallow-rooted, meaning they can topple over easily, and they are susceptible to canker, which are dead sections caused by fungus or bacteria. If a canker appears, destroy any diseased areas. Clean any pruning tools between each cut to keep the disease from spreading.

You may also experience infestations of spider mites on this tree. A natural solution for this problem is to spray with neem oil. Another pest that can attack the plant is bagworm; deal with these by picking off the "bags" as soon as you see them.

4 Things You Didn't Know About Your Leyland Cypress

Can anyone recommend a hardy evergreen that grows very fast?

"I'm sure everyone says that."

You can say that again, and again, and again, and again......

You might want to search the forum where this subject has been discussed to death many many times. You could use a search term like Green Giant. If you have any specific questions about what you find, come back and I'm sure we can get you an answer.

$50 per tree is real expensive if you are talking about Green Giants. Buying fast growing trees that are already 5 feet tall is probably not a good idea. You'll be paying more for less performance. Smaller trees would probably surpass the size of larger trees within just a few years. Smaller trees experience less transplant shock, are less likely to have girdling roots and poor root structure, are easier to plant, are easier to care for, save you time (because they grow faster), and cost less! 2' to 3' Green Giants are a good size if you go with Green Giants.

Getting growth rates of 3' or more a year is possible if the trees are very happy (given the right conditions).

See some of the many many other posts on this subject for other recommendations (other species and mixes of different types of trees) and planting schemes.

Missouri leyland cypress

Leyland cypress

Species of conifer

The Leyland cypress, Cupressus × leylandii, often referred to simply as leylandii, is a fast-growing coniferousevergreen tree much used in horticulture, primarily for hedges and screens. Even on sites of relatively poor culture, plants have been known to grow to heights of 15 metres (49 ft) in 16 years.[2] Their rapid, thick growth means they are sometimes used to achieve privacy, but such use can result in disputes with neighbours whose own property becomes overshadowed.[3] The tree is a hybrid of Monterey cypress (Cupressus macrocarpa) and Nootka cypress (Cupressus nootkatensis). It is almost always sterile, and is propagated mainly by cuttings.

History[edit]

In 1845, the Leighton Hall, Powys estate was purchased by the Liverpool banker Christopher Leyland. In 1847, he gave it to his nephew John Naylor (1813–1889).[4] Naylor commissioned Edward Kemp to lay out the gardens, which included redwoods, monkey puzzle trees and two North American species of conifers in close proximity to each other – Monterey cypress and Nootka cypress. The two parent species would not likely cross in the wild, as their natural ranges are more than 400 miles (640 km) apart, but in 1888, the hybrid cross occurred when the female flowers or cones of Nootka cypress were fertilised by pollen from Monterey cypress.[5]

John Naylor's eldest son Christopher John (1849–1926) inherited Leighton Hall from his father in 1889. Christopher was a sea captain by trade. In 1891, he inherited the Leyland Entailed Estates established under the will of his great-great-uncle, which passed to him following the death of his uncle Thomas Leyland. On receiving the inheritance, Christopher changed his surname to Leyland, and moved to Haggerston Castle, Northumberland.[6] He further developed the hybrid at his new home, and hence named the first clone variant 'Haggerston Grey'. His younger brother John (1856–1906) resultantly inherited Leighton Hall, and when in 1911 the reverse hybrid of the cones of the Monterey cypress were fertilised with pollen from the Nootka, that hybrid was baptised 'Leighton Green.'[5]

The hybrid has since arisen on nearly 20 separate occasions, always by open pollination, showing the two species are readily compatible and closely related. As a hybrid, although fertility of certain Leyland cypress forms were recently reported,[7][8] most Leyland cypress were thought to be sterile, and nearly all the trees now seen have resulted from cuttings originating from those few plants.[5] Over 40 forms of Leyland cypress are known,[9] and as well as 'Haggerston Grey' and 'Leighton Green', other well-known forms include 'Stapehill', which was discovered in 1940 in a garden in Ferndown, Dorset by M. Barthelemy[10] and 'Castlewellan', which originated from a single mutant tree in the Castlewellan estatearboretum in Northern Ireland. This form, widely propagated from the 1970s, was selected by the park director, John Keown, and was named Cupressus macrocarpa 'Keownii', 1963.[11]

Description[edit]

A large, evergreen tree, Cupressus × leylandii reaches a size between 20 and 25 m high, with its leaves giving it a compact, thick and regular habit. It grows very fast with yearly increases of 1 m. The leaves, about 1 mm long and close to the twig, are presented in flaky, slightly aromatic branches. They are dark green, somewhat paler on the underside, but can have different colors, depending on the cultivar. The crown of many forms is broadly columnar with slightly overhanging branch tips. The branches are slightly flattened and densely populated with scaly needles. The tree bark is dark red or brown and has deep grooves.

The seeds are found in cones about 2 cm in length, with eight scales and five seeds with tiny resinous vesicles. With the tree being a hybrid, its seeds are sterile. Over time, the cones shrink dry and turn gray or chocolate brown and then have a diameter of 1 cm.[12]

Taxonomic status[edit]

Cupressus × leylandii is a hybrid of two other cypress species: Monterey cypress (Cupressus macrocarpa) and Nootka cypress (Cupressus nootkatensis). The taxonomic status of Nootka cypress has changed over time, and this has affected the taxonomic status of the hybrid. Nootka cypress was first regarded as belonging in the genus Cupressus, but was later placed in Chamaecyparis. It has become clear, however, that when the genus Cupressus is defined to include Chamaecyparis, it is paraphyletic unless it also includes Juniperus.[1] In 2004, Little et al. transferred the Nootka cypress to Callitropsis.[13] Little (2006) proposed another alternative by transferring all the North American species of Cupressus, including the Monterey cypress (C. macrocarpa), to Callitropsis.[14]

In some of these classifications, this and other hybrids of Nootka cypress become very unusual in being intergeneric hybrids, the only ones ever reported among the gymnosperms. In 2010, Mao et al. performed a more detailed molecular analysis and redefined Cupressus to exclude Chamaecyparis, but to include the Nootka cypress.[15][16] It may be added that attempts to cross Nootka cypress with other Chamaecyparis species have been universally unsuccessful. The scientific name of Leyland cypress depends on the treatment of Nootka cypress. Where Nootka cypress is considered as Cupressus nootkatensis, the hybrid is within the Cupressus genus and is therefore Cupressus × leylandii. If both Monterey and Nootka cypress are considered as species of Callitropsis, the hybrid is Callitropsis × leylandii. However where the parents are treated as being in different genera, Leyland cypress becomes an intergeneric hybrid: if Nootka cypress is within Chamaecyparis, the name of the hybrid becomes ×Cupressocyparis leylandii, and where it is treated as Xanthocyparis, the hybrid becomes ×Cuprocyparis leylandii.[17]

Two other similar hybrids have also been raised, both involving Nootka cypress with other Cupressus species:

Cupressus arizonica var. glabra × Cupressus nootkatensis (Cupressus × notabilis)
Cupressus lusitanica × Cupressus nootkatensis (Cupressus × ovensii)

Adaptation[edit]

Leyland cypress is light-demanding, but is tolerant of high levels of pollution and salt spray. A hardy, fast-growing natural hybrid, it thrives on a variety of soils, and sites are commonly planted in gardens to provide a quick boundary or shelter hedge, because of their rapid growth. Although widely used for screening, it has not been planted much for forestry purposes. In both forms of the hybrid, Leyland cypress combines the hardiness of the Nootka or Alaska cypress with the fast growth of the Monterey cypress.[5]

The tallest Leyland cypress presently documented is about 40 m (130 ft) tall and still growing.[18] However, because their roots are relatively shallow, a large leylandii tends to topple over. The shallow root structure also means that it is poorly adapted to areas with hot summers, such as the southern half of the United States. In these areas, it is prone to develop cypress canker disease, which is caused by the fungusSeiridium cardinale. Canker causes extensive dieback and ultimately kills the tree. In California's Central Valley, they rarely live more than 10 years before succumbing, and not much longer in southern states like Alabama. In these areas, the canker-resistant Arizona cypress is much more successful. In northern areas where heavy snows occur, this plant is also susceptible to broken branches and uprooting in wet, heavy snow. The tree has also been introduced in Kenya on parts of Mount Kenya.

The sap can cause skin irritation in susceptible individuals.[19]

Commercialization[edit]

Leylandii used as windbreak

In 1925, a firm of commercial nurserymen specialising in conifers were looking for a breed that was fast-growing, and could be deployed in barren, windy and salty areas such as Cornwall. Eventually they found the six original trees developed by Leyland, and began propagating the species.[20] In 1953, a freak tornado blew down one of the original trees at Haggerston (the other original five trees still survive), on which the research division of the Forestry Commission started developing additional hybrids. Commercial nurseries spotted the plant’s potential, and for many years, it was the biggest-selling item in every garden centre in Great Britain, making up to 10% of their total sales.[18]

Uses[edit]

They continue to be popular for cultivation in parks and gardens. Leyland cypress trees are commonly planted to quickly form fence or protection hedges. However, their rapid growth (up to 1 m per year), their thick shade and their large potential size (often more than 20 m high in garden conditions, and they can reach at least 35 m) make them problematic.

Cultivars[edit]

The cultivar 'Gold Rider'[21] has gained the Royal Horticultural Society's Award of Garden Merit (confirmed 2017),[22] though the original hybrid has now lost its AGM status.[23]

Other cultivars include 'Douglas Gold', 'Leighton Green', 'Drabb', 'Haggerston Grey', 'Emerald Isle', 'Ferndown', 'Golconda', 'Golden Sun', 'Gold Rider', 'Grecar', 'Green Spire', 'Grelive', Haggerston 3, Haggerston 4, Haggerston 5, Haggerston 6, 'Harlequin', 'Herculea', 'Hyde Hall', 'Irish Mint', 'Jubilee', 'Medownia', 'Michellii', 'Moncal', 'Naylor's Blue', 'New Ornament', 'Olive's Green', 'Robinson's Gold', 'Rostrevor', 'Silver Dust', 'Variegata', 'Ventose', and 'Winter Sun'.[9]

Legal aspects[edit]

The plant's rapid growth and great potential height can become a serious problem. In 2005 in the United Kingdom, an estimated 17,000 people were at loggerheads over high hedges, which led to violence and in at least one case murder, when in 2001, retired Environment Agency officer Llandis Burdon, 57, was shot dead after an alleged dispute over a leylandii hedge in Talybont-on-Usk, Powys.[18]

Part VIII of the United Kingdom's Anti-Social Behaviour Act 2003, introduced in 2005, gave a way for people in England and Wales affected by high hedges (usually, but not necessarily, of leylandii) to ask their local authority to investigate complaints about the hedges, and gave the authorities in England and Wales power to have the hedges reduced in height.[24] In May 2008, UK resident Christine Wright won a 24-year legal battle to have her neighbour's leylandii trees cut down for blocking sunlight to her garden.[25]

Legislation with similar effect followed in Northern Ireland, Isle of Man and Scotland.

Notable specimens[edit]

At the U.S. Space & Rocket Center in Huntsville, Alabama, twenty leyland cypresses line an elevated berm in their Rocket Park area.

Leyland Cypress Evergreen Trees

Leyland cypress trees are an exceptionally fast-growing tree that can create a lush, natural privacy screen in just a few years. These low-maintenance evergreens keep their bluish-green, needled leaves year-round, and are tolerant of many soil types and a range of sunlight. If you want to block out unwanted noise, shield a view of a busy street, or get some privacy from your neighbors, the Leyland cypress is the perfect tree for you.

Leyland Cypress Trees at a Glance

  • Fast-growing
  • Low-maintenance
  • Excellent for privacy screens
  • Green year-round
  • Salt-tolerant
  • Shallow roots

Appearance

Leyland cypress trees grow in a pyramidal, conical shape with flattened sprays of bluish-green, needled leaves. They grow to an impressive height of 40-60 feet if not pruned down, with a spread of 15-20 feet. Growing 3 feet or more by their second year, Leyland cypress trees achieve this great height quickly.

Hardiness Zones

USDA Hardiness Zones show the best regions to grow various types of plants. Leyland cypress trees thrive in Zones 6-10, across a large swath of the country from the West Coast to the East Coast, with greatest growth from zones 6-8.

Planting

The best time to plant your tree is during its dormancy in mid-fall. Plant your Leyland cypress tree in an area with well-drained soil that receives full sunlight to partial shade. Don’t plant your tree directly on the property line, because this fast-growing, massive tree can grow onto your neighbor’s property.

Dig a hole twice the width of the root ball. You want to plant the tree so that is even with the surrounding soil. Gently tease the roots of the tree before you place it in the hole to encourage the roots to grow outward. Backfill the hole with the soil you dug out, and create a ring of mulch around the tree, not letting it touch the trunk. Water your tree every day for one week, then water every other day. By the third week, you can water as needed.

If you plant multiple trees, space them out 6-10 feet apart.

Growing Conditions

Leyland cypress trees have a reputation for being low-maintenance, adaptable to a range of sunlight and soil conditions. They don’t even need pruning, unless you want to achieve a specific, consistent height.

Sun and shade

Leyland cypress trees flourish in full sunlight—at least six hours of direct, unfiltered sunlight per day. They can also tolerate partial shade.

Soil

The soil must be well-drained, but other than that, Leyland cypress trees aren’t picky. They will grow in a wide range of soils, including alkaline, acidic, sandy, clay, and loamy.

Watering

Water your Leyland cypress tree deeply and irregularly, about once a week, giving it about an inch of water total each time. As your tree ages, you can give it water less frequently. Do not use an irrigation system, because that can overwater your tree and lead to root rot.

Fertilizing

You should fertilize in early spring, before your Leyland cypress tree has new growth. Use a slow-release, balanced fertilizer with an NPK value of 10-10-10. You don’t need to fertilize every year, and should leave it up to your judgment.

Pruning

If left unpruned, Leyland cypress trees will reach great heights. However, they will maintain their pyramidal shape without any intervention. If you want a hedge of a certain height and to encourage dense growth, prune your tree annually.

Frequently Asked Questions

How far apart should you plant them?

To give them adequate room to grow, you should plant Leyland cypress trees at least 6-10 feet apart.

When is the best time to plant them?

Plant your tree in mid-fall when it is dormant.

How long do they live?

Leyland cypress trees live about 10-25 years.

Do they have invasive roots?

Leyland cypress trees have a shallow, non-invasive root system.

Which Is Better: Cypress or 'Green Giant' Arborvitae?

Homeowners and landscapers looking for a fast-growing, evergreen tree to be used as a hedge or privacy barrier often narrow their choice to two plants: The "Green Giant" arborvitae (Thuja standishii x plicata "Green Giant") or a cypress called the Leyland cypress (× Cuprocyparis leylandii). Because each plant has its own pros and cons, which is better depends on personal preference and where and how the tree will be used.

One Tree or Two

A tree's background doesn't necessarily make it better than another tree, but the differences can still be interesting. One difference between these two trees is that one is a cultivar of two species and the other is a cultivar of two genera. Several trees in at least three genera are called "cypress," including trees in the Taxodium, Cupressus and Chamaecyparis genera, but it is the Leyland cypress that is the most commonly grown in home landscapes. The Leyland cypress is a hybrid of two cypress trees from the Cupressus and Chamaecyparis genera. "Green Giant," on the other hand, is a cultivar of two species from one genus: Thuja plicata and Tjuja standishii.

Looks May Be Everything ...

It's the fast growth and evergreen foliage of both trees that attracts home gardeners to these plants. "Green Giant" grows to a maximum average height of about 60 feet, with a maximum width of about 14 feet. In optimum environments, the tree can grow up to 4 feet per year. The Leyland cypress is a bit larger -- it grows to a maximum height of about 70 feet, with a maximum average width of around 15 feet. It grows up to 3 feet per year during its early years, according to Missouri Botanical Garden, and in the wild it can reach heights of over 100 feet. "Green Giant" has true, very dense green foliage, whereas the Leyland's foliage is less dense and more of a grayish-green hue.

... But Consider the Climate

"Green Giant" tolerates cold better than the Leyland cypress, but the latter tolerates heat better than the former. "Green Giant" is hardy in U.S. Department of Agriculture plant hardiness zones 5 through 8, and the Leyland cypress is hardy in USDA zones 6 through 10. Once established, the Leyland cypress can tolerate drought. "Green Giant," on the other hand, does not like hot, dry conditions.

A Caring Environment

Besides the climate, you also need to consider the environment. If you live in a hot climate and the planting site is shaded in the afternoon, for example, then the best tree would be "Green Giant," because it grows best with some afternoon protection from the hot sun. On the other hand, the Leyland cypress grows best in full, hot sunlight. Both trees like rich, well-draining soil, but "Green Giant" prefers soil on the moist side, whereas the Leyland cypress will tolerate drier conditions.

Ponder the Pests

When the Leyland cypress first burst onto the scene, it quickly became extremely popular. Easy to shape and fast-growing, it was rarely bothered by insect pests or diseases. Over time, however, this changed, according to the Clemson Cooperative Extension, and now the tree is known to suffer from a wide variety of problems, including issues with diseases and insect pests. Because the trees are so large, it is almost impossible to treat a sick Leyland cypress. Today, "Green Giant" is promoted as a better alternative to the Leyland cypress primarily because it is far less likely to succumb to serious disease or insect pests.
