What is a blue spruce?

Blue spruce, or picea pungens is an evergreen tree originating in Western North America. The plant is also referred to as Spruce Colorado and is found in certain parts of the Rocky Mountains. It is physically characterized by a thick crown and sharp needles. This tall tree grows slowly, especially during the first years. It produces a good shadow tree if it is in a cold climate and gives a partial full sun, well -drained soil and irrigation and mulch.

This specimen primarily occurs in the middle and southern rocky mountains in the Western United States. This area includes parts of Wyoming, Idaho and Utah, as well as Arizona, New Mexico and Colorado. The tree population thrives near streams and mountain valleys.

The tree is tall, upright evergreen. Its large, thick crown spreads in a column or pyramid shape and measures between 10 and 20 feet (approximately 3 to 6 meters). Extremely sharp needle color from gray to blue and its fruit cones are long, cylindrical and chestnutbrown seeds similar to paper scale. The average spruce grows to the height of adults between 30 and 50 feet (about 9 and 15 meters). However, a tree located in his native habitat can reach significantly above 75 feet (about 23 meters).

This tree works well for use as a tree of shadow or screen privacy due to its thick crown. The grass does not grow under it, so it needs a clear area in which it can grow, best balance the surrounding soil or on the slope above it. Blue spruce needs radiator temperatures to be successful, ideally on 39 ° and 43 ° Fahrenheit (about 3.9 ° to 6.1 ° C).

light requirements for blue spruce are flexible because it is well in full or partial sun. It has a slight tolerance of drought, but benefits in a damp, well -drained soil. The tree also adapts to clay, sandy or alkaline land and rot with a high salt content. Irrigation and mulching can benefit fromPlant for moisture balance.

There are some concerns about the growth of blue spruce. It is susceptible to some pests and diseases, including the upper needle, which is bored in the leaf and removes the center, and aphids and mites can also be a problem. Diseases and castings of needles can infect the plant and cause yellow leaves and drop.
