If your prying neighbor has got onto your nerves, then one way to reduce the visibility of your house happenings is by planting some fast-growing evergreen trees. These trees are very beneficial because they retain their leaves all the year round. Some of the fast-growing trees are Norway Spruce, Leyland Cypress, etc.
Evergreen trees are those trees that do not shed all their leaves at once. This means they show the presence of leaves all through the year. These trees gradually replace their leaves throughout the year, with newer leaves replacing the older ones. They grow wide and thick and can be the best means of enhancing privacy in the neighborhood. The other kind of trees are deciduous trees, which shed their leaves seasonally. However, such trees fail to provide the much-needed privacy all the year round. This is why evergreen trees are favored when it comes to natural privacy fences.
Besides this, evergreen trees also muffle noises and provide ample amounts of shade, all through the year. Some evergreen trees are strong and able to withstand strong winds, which is why they are often used as windbreakers. Then again, some are chosen for tree-plantation projects. They are also used as Christmas trees.
However, there are quite a few evergreens that take a long time to grow, and waiting for such trees to grow can be quite cumbersome. This is why selecting the fast-growing ones will come in handy. Let’s find out more about fast-growing evergreen trees.
Fast-growing Evergreen Trees
- Native to Europe, this tree is also referred to as the European spruce. However, it has been introduced to the United States and is widely used as an ornamental in Ohio.
- Norway spruce is the fastest growing of all spruces and grows to a height of 100-140 feet and over 25-40 feet wide. The tallest Norway Spruce recorded as of date was that from Perucica Virgin Forest, Sutjeska National Park, Bosnia-Herzegovina, with a height of 207 feet.
- On an average this tree grows to a height of 2 to 3 feet per year during the first 25 years of its life, provided the conditions are favorable. Unfavorable conditions curb the growth to a mere one feet a year. The growth slows down once the tree reaches 20 feet in height.
- It is also highly disease-resistant. The barks of these trees are orange-brown and the leaves are dark green and needle-like. They are conical when young and grow columnar in shape, as they mature. The Norway Spruce looks most attractive during its youth and as the tree gets older, the symmetry in the upper portion of the tree is lost.
- Since this species can withstand cold climate, it is a favorite fast-growing evergreen tree grown in cold regions. Moreover, their fibrous root system enables them to withstand strong winds, which is why they are often used as windbreakers in windy regions.
- They are widely grown for timber and paper. They were also commonly used as Christmas trees, however, their inability to hold their needles once they are cut, plummeted their popularity as Christmas trees.
- Norway Spruce is not meant for smaller yards, and need plenty of room to grow well.
- Often this pure Norway Spruce is confused with the hybrid Norwegian Spruce (Siberian Spruce and Norway Spruce hybrid).
Leyland Cypress (Cupressus x leylandii)
- Named after its discoverer, C.J. Leyland, the Leyland Cypress is a hybrid resulting from a cross between Monterey cypress (Cupressus macrocarpa) and Alaska Cedar (Chamaecyparis nootkatensis).
- They are fast-growing evergreen conifers sought-after for their wood, aesthetic value and wind-breaking capacity. They are also used as Christmas trees.
- Since these trees grow so thick, they are popularly grouped together and grown to build fences, hedges, screens, windbreakers and walls (best for privacy). They can grow to about 100 feet high and 25 feet wide, at the rate of 3 to 4 feet a year if allowed to grow wild.
- However, if this tree is allowed to grow wild, structural defects are seen to occur, which eventually shortens its lifespan. Regular pruning is required for improved tree structure.
- Having said this, excessive pruning can also destroy these trees. Pruning once between the months of May to August is more than sufficient.
- Leyland Cypress requires adequate sunlight to grow in and lack of it thins its growth. However, it is drought-tolerant and can grow on less nutritious soil too.
- Their lifespan is only about 20-25 years.
- Leyland Cypress can be described as ‘high maintenance’! Several people get Leyland Cypress for hedging, however, it’s important to remember these plants grow really fast and require a lot of time to keep them trimmed. They can grow really fast and owners get overwhelmed. They are best-suited for large commercial establishments or parks.
- Diseases like Seiridium canker, Botryosphaeria dieback, Cercosporidium needle blight, etc. affect this species, which makes maintenance even more important.
Scotch Pine (Pinus sylvestris L.)
- Scotch pine or Scots pine, again a native of Europe is an evergreen, fast-growing coniferous tree, whose natural range spreads across the whole of Northern Europe. Scotch pines are believed to be the first conifers to be introduced to North America by European colonists.
- In Europe, it is commercially grown for its timber, and is also popularly known as ‘European Redwood’. However, in the US, it is grown primarily as Christmas trees and for ornamental purposes.
- Scotch pines grow at a rate of 2-3 feet every year. Under favorable conditions it grows to a height of 120 feet, however, the average height ranges from 60 to 90 feet, with the diameter ranging from 20-40 feet. The average height varies from country to country. In the US, the average height is about 60 feet.
- These trees are highly adaptive and can even grow in dry soil, but the growth rate is much slower.
- The lifespan of these trees range from 100 to 300 years. However, the oldest Scotch Pine (in Sweden) is recorded to be around 700 years old.
- The distinctive feature of this tree is its bright orange, scaly bark that is found mostly on the upper trunk and branches. On the lower portion of the trunk, the bark features a more brownish, dark and hard appearance. The leaves are needle-like, grouped into pairs and blue-green in color.

These trees do well in any kind of soil, be it sandy, saline, volcanic or even nutritionally deficient soil. They form great windbreakers and help in erosion control. They are also used as firewood.
Australian pines are commonly found in Florida and their fast-growing nature has enabled them to establish themselves well, however, this has caused problems in the natural ecosystem. These trees release a herbicide that kills any plant growing close to it. This is not healthy for the ecosystem on the whole. This is why they are listed amongst the ‘most invasive plants’, by the Florida Exotic Pest Plant Council.
