QuestionWe would like to use the Leyland Cypress for privacy. We have a 3/4 acre lot and will be planting along chain link fence. Will this pose a problem and will be need to keep them pruned along the fenceline?
AnswerLeyland cypresses, XCupressocyparis leylandii, are not fairing well in many landscapes. It is a fast growing tree used in boarders and screens that had relatively few pest problems. Now is has been suffering from branch die-back. Sadly, it can cause the death of the tree. Seiridium canker is the cause. This disease is not to the point of wiping out this tree, but I would recommend not planting this tree as it likely will in the future be a major concern. Why plant a tree that is not going to be healthy or is suspect? Thus landscape designers should seek a replacement for the Leyland Cypress. One great choice is the Green Giant Arborvitae. Green Giant arborvitae is becoming a superstar in the plant world. It is the most popular arborvitae next to the Emerald Green Arbor vita. The reason for its success is that it fills landscape needs that are important. It will help block large unsightly neighbors quickly and is basically pest free.
The Green Giant Arborvitae is recommended for growing as a hedge or privacy buffer along a property line, or driveway. Thuja Plicata, Western Red Cedars are ideal "windrow" trees. In a row, they'll truly diminish the wind. The Green Giant Arborvitae is justifiably considered wind resistant considering the windswept mountains of the Pacific northwest. The wood itself is weak, but it is very light. Green Giant Arborvitae do have better deer resistance than most arborvitae.
Thuja Green Giant is becoming more and more popular among landscapers, growers, and homeowners alike. This hardy, fast growing, conifer makes a perfect privacy screen in just a few short years.
Green Giant will grow from 3 to 5 feet per year and will eventually grow to 50 feet or more with a fairly narrow spread. The color is a deep lustrous green and is pleasantly fragrant.
Green Giant will grow in a wide range of soils in zones 5 to 8 and prefers a deep well drained fertile soil although it adapts well to frequently saturated clay soils. This is a tough tree and will not easily suffer damage from high wind or heavy ice and snow loads.
Green Giant is drought tolerant after it is well established, exhibits no significant pest or disease problems, is deer and bagworm resistant and is hardy to -25F.
This new USDA US National Arboretum release as Green Giant has been evaluated since 1967 and will become the outstanding alternative screening-evergreen to the disease prone Leyland Cypress in the south and to the Hemlocks that are dying throughout New England. Plant 5 to 6 feet apart for a really fast privacy screen, otherwise 10-12 feet apart. Green Giant can be trimmed to any height and width.
Another good hedge evergreen plant is Cleyera. Here is a web link with more information on this plant. http://www.floridata.com/ref/t/ternstro.cfm
