The Arborvitae is a medium growing evergreen growing (1-2ft per year). It requires almost no care when used as a hedge or screen. Pairs of these hardy trees make great accents for doors and garden gates. And single trees soften house corners. This tree shows a narrow columnar form in youth, eventually broadening to conical at maturity. Its leaves are scalelike, forming flattened, horizontal sprays. Most arborvitae retain their green coloration all winter. Tall and elegant, the American arborvitae may be the right solution to your landscaping challenges. The American arborvitae grows to a height of 40–60' and a spread of 10–15' at maturity. A 2 ft potted tree can be over 8 ft tall in 5 years in good soil, adequate moisture, and total weed and grass control.
The Blue Spruce is a slow growing (6-12 inches per year) evergreen that has a needle that is green or bluish and is about 1 inch long. Color can be variable and the needles are very sharp. It does not shed its needles but keeps them for 10 years or longer with its branches extending to the ground. This tree is a native to the Rocky Mountains. It will grow to 60+ ft tall and 15 ft wide and is very wind firm due to its large spreading root system and tough flexible wood. Due to its shape, heavy snow and ice storms cause little damage. Deer will not normally eat this species unless nothing else is available. It will grow well in hardiness zones from 2-7 and will do quite well in poor soils that other spruces do not like. It is very drought resistant needing only 15" or less per year of rain and can tolerate hot dry summers better than many other spruce species.
The Canaan is a medium growing (1-2ft per year) evergreen. Their needles are flat needle-like about 1 inch long and have a nice green color. It does not shed its needles but holds them for 10 years or longer. The Canaan fir will grow up to 60 ft tall and 15 ft wide, and has the traditional evergreen shape and a very nice fir smell. It will grow on heavier soils and higher ph soils remarkably well. Being from the east with higher precipitation and humidity, it is not bothered by needlecast and canker diseases that western species of fir (Douglas or Concolor) are. Recommend planting on a well-drained soil or on sloping heavy ground so water can run off and not be excessive. We have noticed that this tree is more drought resistant than many other conifers.
The Norway Spruce is our favorite and best large evergreen. The Norway Spruce is a fast growing (2-3 ft per year) evergreen that has dark green needles that are 1 inch long, and can grow up to 5 ft a year in a good weather year. It does not drop its needles and its branches extend to the ground, giving excellent wind protection. It is a native of Central and Eastern Europe. It will grow to 100+ ft tall and 25+ ft wide, it is very wind firm due to its large spreading root system and tough flexible wood. It can live a very long life of over 100 years. Due to its shape, heavy snow and ice storms cause little damage. Deer will not normally eat this species unless there is nothing else available. It is able to take more moisture than other species and should be considered where soils can stay moist and where the land is level and does not drain as well. Does not do well where the soil is constantly wet or swampy. The Norway Spruce has few disease problems unless stressed.
The White Pine is a fast growing (2-3 ft per year or more) evergreen and is native to eastern North America. In Sep. through Oct. this pine "sheds" all of its needles that grew out the previous year. When grown in the open its branches extend to the ground, when grown in windbreaks they usually loose these lower branches, which is common in the pine family. It will grow up to 100+ ft tall and 25+ ft wide; its large spreading root system is very wind firm, but its branches are slightly brittle and more susceptible to damage by snow, ice, and windstorms. It prefers a well-drained soil and does not like to have its roots too wet. The White pine can grow well in sandy conditions where the spruce would not do as well. It is quite adaptable to dryer sites if not planted too closely together. The White pine tree is a recommended tree for fast growth.
The White Spruce is a medium to fast growing (2ft plus per year) evergreen native to Canada and Northern United States. It does not drop its needles, and its branches extend to the ground making it a good wind protection and privacy screen tree. It will grow up to 60+ ft tall and 20+ ft wide and is very wind firm. It can live 80+ years in windbreaks. Due to its shape, heavy snow and ice storms cause little damage. Deer will not normally eat this species unless there is nothing else. The White Spruce can take more moisture and does well in level areas that can be too wet for other species during wet years. It has few disease problems unless stressed. Fungal diseases rarely effect this species, and insect pests rarely occur on newly planted, older, or stressed trees. A 2 ft tall potted tree should be over 8 ft tall in 5 years provided it has good soil, adequate moisture, and most of all, total weed and grass control.
