Leyland Cypress – Not A Good Choice For Privacy Screens

Resources: Community


Leyland CypressOften used as privacy screens, Leyland cypress’ are marketed to homeowners as a beautiful, fast growing solution for their privacy needs. But what most nurseries neglect to tell homeowners is that Leyland Cypress’ really only thrive in well-drained soil and sunny locations. And even when properly planted and in the correct location, these trees are less than hardy. In fact, Leyland Cypress’ are susceptible to a host of diseases, insects, and environmental stressors.

Common Problems with Leyland Cypress’

The increased frequency of these disease and insects attacking Leyland Cypress’ is seen because of the rise in popularity of Leyland Cypress’ as privacy screens. This species overwhelming popularity as a choice for privacy screens caused a lack of variety in the landscape. Lack of variety in the landscape, also referred to as monoculture, causes formerly minor pest issues to develop into major problems.

Seiridium & Botryospaeria Canker: Easily the most concerning for Leyland Cypress’, Seiridium & Botryospaeria are both fungi that cause dieback in Leyland Cypress’. The first symptoms are typically a yellowing or fading of foliage on scattered lateral branches that later turns a reddish brown. The worst part about these fungi is that the common treatment used to fight fungi, fungicide, is largely ineffective against it.

Cercosporidium Blight: This serious disease first discovered in 1887, has recently become a big problem for Leyland Cypress’. Symptoms include rusty brown patchy needles and twigs and overall dieback.

Bagworms: Native to the eastern US, bagworms are defoliating caterpillars that create unsightly cone shaped bags. When populations get high, excessive feeding can strip away large quantities of leaves.

Spider Mites: Spider mites are a common enemy of anyone who cares about their landscape plants. Classified as arachnids, these tiny tree bugs are less than 1/20 inch long when fully mature and look like moving dots to the naked eye.  Their ability to rapidly reproduce allows large populations to develop fast and severely harm your plants before you even realize you have a problem.

Root Rot: In soils that don’t drain well, Leyland Cypress’ will most likely develop root rot at some point. This is a condition caused by fungi which attacks the tree’s root system essentially causing the roots to rot away, hence the name. Root rot can usually not be cured but only suppressed by routine fungicide treatments and proper maintenance.


Alternatives To Leyland Cypress’

Tall Narrow Conifers: If you like the form of Leyland Cypress’ and want a similar tall narrow conifer consider:

  • Arizona cypress for dry sites in full sun
  • Green Giant arborvitae for moist, but well drained, soil in full sun
  • Japanese cedar for a tall screen in a partly shady area.

Hollies: Hollies are a great choice for tall, narrow situations and less restricted areas. They grow well in either sun or part shade.

  • Savannah holly, Foster’s holly, and the Aqupernyi hollies (Dragon Lady, and Carolina Sentinal) are great for narrow areas.
  • Lusterleaf holly and Nellie R. Stevens holly are good for less restricted areas.
Little Gem Magnolia
Little Gem Magnolia Privacy Screen

Broadleaf Evergreens: These evergreens make beautiful dense privacy screens. As an aesthetic plus they provide flowers or berries in certain seasons.

  • Magnolias: For tall and narrow privacy screen look for certain cultivars of southern magnolias such as Alta, Bracken’s Brown Beauty, and Edith Bogue. For medium height and compact look for the cultivar Little Gem. For moist soils look for Sweetbay Magnolias. Cultivars Henry Hicks and Santa Rosa can be used for most situations.
  • Tea Olive: For tall privacy screen opt for fragrant tea olive, and fortune’s tea olive.

The Best Solution – Mixed Species: When a plant becomes so popular that it is planted everywhere, formerly minor pest problems can develop into major problems. The issue is that even if you buy a species that isn’t popular today, it could become popular and suffer the same fate as Leyland cypress’.

The real solution isn’t picking the best species, it’s diversifying your landscape and privacy screens. By grouping multiple species together in small clusters of 3 or 5, either in a single row, or in an alternate layered planting where possible you can help prevent the spread of problems from one tree to the next. In mixed screens, even if one species does develop issues and needs to be removed and replaced, the entire privacy screen will not be sacrificed.

If you have a privacy screen that’s important to your landscape have one of our arborists come out and develop a plant health care plan. Give us a call at 703-573-3029 or schedule an appointment with one of our arborist.

We have been using RTEC for years and were very pleased with the recent tree maintenance work they did for us. As always, we got good advice from their arborist Ben,. The crew that did the work is highly skilled, and they did a great job trimming our trees. They worked safely and efficiently, in addition to leaving the yard clean after they finished the work.

RTEC was at my house today to removed a large Magnolia that was badly damaged by the recent snow. They did a fantastic job at a very reasonable price. They arrived right on time, worked efficiently and quickly and cleaned up so well it was hard to tell anything have been disturbed. Over the past several years, I have used RTEC for all the services I checked above, and have always been very pleased with their service and professionalism. I also appreciate that they are not eager to take down trees that don't need to come down. In this case, the damage was too extensive for the tree to recover.

Once again, RTEC has done a great job. The team showed up right on time and performed all the work that we agreed to. They kept us informed as to progress, coordinated with us concerning our maple, and made recommendations concerning ongoing support for our trees. At the end of the day, they thoroughly cleaned up the debris and left our yard in pristine condition. WELL DONE.

Not our first time but this time was tricky removal of a large dead tree leaning on a healthy tree. Quick response for estimate, good timing to removal, all clear and healthy tree still fine.

We’ve used RTEC for many years for tree maintenance and can’t say enough good things about their service. We use them for tree trimming and for regular treatments to maintain our trees’ health and deal with pests and prevent disease. Their arborist Ben has been especially helpful with advice. RTEC also been especially helpful in emergency situations, once coming to cable a massive, heritage oak in our yard right before a hurricane was about to hit. Highly recommend.

RTEC did an excellent job onsite of removing dead branches from our 80+ year old trees, and trimming other growth too close to our home.
