Screening With Evergreens
Screening plants are used in the landscape to make a sort of living wall. Screens are used for privacy, wind protection, and noise control, though most commonly people use them for the sake of privacy. Using evergreen trees or shrubs to form your screen is ideal, so that you can enjoy the year-round benefit of your screen.
A commonly used evergreen screening plant is the Leyland Cypress. Unfortunately, these trees have many pests and diseases. They are generally planted too close together, making them even more susceptible to having problems. Because these trees are so overplanted, their problems are widespread, and they generally will decline over time. Due to this, it is not recommended to use the Leyland Cypress in a new planting.
The good news is, there are plenty of other plants out there which can be used for an evergreen screen. One of the best replacements for the Leyland Cypress, is the Thuja ‘Green Giant’, or ‘Green Giant’ Arborvitae. The ‘Green Giant’ is fast growing, and can be used like a hedge in place of a Leyland. The ‘Green Giant’ currently has no widespread disease or insect problems. Aside from this, there are many Junipers and Hollies, which you could consider for your landscape. Always remember to match your plant selection to the site you will be planting. If you have a wet site, choose a plant that does well with a lot of water, and vice versa.
