A row of evergreen fast growing privacy trees or shrubs can become a living privacy fence that blocks noise, reduces air pollution, slows the wind, and, most noteworthy, hides an unwanted view. It isn’t hard to grow a privacy screen and it doesn’t take as long as you might think. Fast growing privacy trees are your best choice!
First of all, decide how tall your privacy screen needs to be. You may be able to get by with a 6-8 foot hedge, or you may need a taller living wall of majestic conifers for privacy that measure up to 30 feet, 40 feet, or 50 feet.
Our favorite trees for tall privacy screens are cone-bearing evergreens — such as cedars, cypress, junipers, and pines. Evergreen conifers tend to grow fast and have very low maintenance requirements, therefore needing less pruning.
For lower screens, a dense hedge of broadleaf fastest growing evergreen trees just 6-8 feet high might be all you need. Evergreen shrubs spaced 2-4 feet apart will fill the bill nicely. Sky Pencil Holly also make a great option!
For low, hedge-like screens, we recommend Walter viburnum, Boxwood, Podocarpus or any of the evergreen hollies such as Perfect Plant’s Oak Leaf Holly trees. They can get up to 12 feet.
To create a classic, formal screen — plant a single species, evenly spaced, in a straight line. However, planting a mixture of different kinds of evergreens adds diversity and architectural interest to your landscape. Also, a mixture of species could minimize the spread of pests or diseases should they rear up. When considering the aesthetics, try planting in clusters rather than a simple straight line. Thuja ‘Green Giant’ makes one of the best fast growing evergreen screens. These beauties are capable of putting on 3-5 feet per year in height; they are adaptable to most soil types, and they are drought tolerant. Read more about the Thujas here. Leyland cypress is another good choice since they grow fast and quickly fill the gaps between individual trees spaced 5-8 feet apart.
Norway spruce and Colorado spruce are among the best for wind breaks. Japanese cedar, Italian cypress, American arborvitae, and Canadian hemlock are other good choices for tall privacy screens. Note that Canadian hemlock tolerates shade better than other conifers, but is not suitable for hot climates.
Emerald Green Arborvitae is popular because it doesn’t grow more than 2-3’ wide, and doesn’t require any pruning. For really big screens, consider Leyland Cypress and Excelsa Cedar (a cultivar of giant arborvitae), both of which can get up to 20’ wide. Douglas Fir and giant arborvitae get even bigger, growing as wide as forty feet at maturity.
When planting a privacy screen you should position the trees at least twelve feet away from your home or foundation. You will also want to stay at least six feet away from patios, fences, and other structures. If planting under a utility line you will want to use trees or shrubs that will not get too tall. Also, pay attention to their width at maturity and space your new plants as far apart as their mature width. You might want to take into consideration if it is a deciduous tree – meaning it will lose it’s leaves over the winter and flush out in the spring with all new leaves. Also shade trees are an option if you want some nice land underneath to sit and relax under.
The biggest thing to take into consideration for your fastest growing trees is USDA plant hardiness zones. Be sure to check those here before purchasing and planting your trees in early spring. We have some great options! Listed below are our favorite fastest growing evergreen trees:
