If you love blue spruce trees as much as we do then you know how special these trees really are. They are so much more than just simple trees. We previously discussed some amazing blue spruce tree facts, but these trees are just so impressive that one list simply could not do them justice. So here are five more great facts about the wonderful blue spruce.
A lot of species have colors in their names, but they don’t always deliver on that promise. Blue spruce trees are noticeably blue-hued, though, because of the waxy, powdery layer that is found on the needles. It is truly a unique characteristic that few other species have.
Wax Off Blue
Remembering that the blue comes from the waxy layer of the needles, it’s actually possible for a blue spruce to lose its color. It often happens when the tree is under attack by an outside infestation like cankers or pine weevils. While you may be tempted to use a treatment to help your trees ward off this problem, it’s important to remember that some of these pesticides are capable of removing the blue wax coating. Test any insecticide on a small portion of the tree before making any full application.
Although they aren’t the quickest growing plants on earth, blue spruce trees grow at a pretty rapid and consistent pace. The standard growth rate for a blue spruce is about 12 inches a year, but in ideal growing conditions, the most expeditious spruces can gain more than 2 feet of growth in a single growing season.
Once a blue spruce tree has gained its footing and has established a steady growth, there are very few things in nature that can hurt it. They can withstand droughts and air pollution, and the spiky foliage prevents deer and rabbits from chowing down on the branches. Blue spruces are also very hardy when it comes to fending off pests or diseases, making them adaptable in all sorts of conditions.
In Colorado, the blue spruce has been the state’s official state tree since 1939, but school children in the state voted to give it that designation nearly five decades earlier. On Arbor Day in 1892, kids around Colorado voted the blue spruce to this prestigious honor, says State Symbols USA.
