A Guide to Growing Siberian Spruce
Before getting into information for growing the Siberian Spruce, we wanted to provide a brief overview of spruce trees overall. One fact that most people are unaware of is that there are only around 35 species of the spruce tree anywhere in the world. This type of tree grows naturally in forests with cool climates. For instance, spruce trees are commonly found in areas of North America, Europe, and Asia. Although the spruce and pine are closely related their appearance is completely different.
One reason that people choose the Siberian Spruce is that like all spruce, this tree grows upright, reaching as high as 60 feet upon maturity, as well as 20 feet wide. However, other types of spruce can grow to 200 feet tall. Because of the height of the spruce, it is the perfect choice as a wind or privacy break. For instance, a homeowner whose home backs up to a freeway could plant a line of spruce to help block out noise or a home sitting up on a hill could use spruce to block the wind.
Of course, the look of the Siberian Spruce is attractive so it makes a great addition to a home or business just because. The trunk of this tree is slender and the branches are actually on the shorter side with an upward sweep. In fact, as this spruce matures, it grows naturally into a narrow pyramid. The needles of the spruce are a dark green that consist of two slim strips of white on the underside.
When grown within the United States, the Siberian Spruce is recommended for people living in hardiness zones of four through seven. For these zones, winter temperatures could drop as low as minus 30 degrees and in the summer increase as high as 86 degrees. Obviously, this species of the spruce tree is extremely versatile regarding the climate in which it could be grown. For this reason, it is common to see spruce from the east to west coast and places in between. One note is that this particular spruce does not tolerate temperatures of 86 degrees for 120 days or longer.
For the soil in which the Siberian Spruce thrives, it needs to be moist and fertile. In addition, it is important that the soil have good drainage. Not only does this spruce tolerate landscape soils but it also does relatively well in soil on the acidic side. However, this type of spruce could also be grown without any problem in clay, sandy, and loam soils. In other words, while this spruce has a favorite soil type, it does well in just about all soil conditions.
The best place to plant this type of spruce tree is in an area with full sun to partial shade. For the healthiest tree, choose an area that would receive varied periods of direct sun, such as four to ten hours or more. That way, the environment mimics the origin of the spruce while growing in the forest. In addition, providing the spruce with the right amount of direct sun would help the branch structure shape properly so the appearance would be beautiful. For humidity, the Siberian Spruce prefers states with high levels but again, it is so adaptable that it does well in states with low to moderate humidity levels.
