Facts and Steps to Plant and Care for a Colorado Blue Spruce

The Colorado blue spruce is one of the best ornamental trees that can be found and grown in American soil. These sturdy giants can grow as tall as 100 feet and are usually found along the stream banks, valleys and high altitude areas of Wyoming, Arizona, New Mexico, Idaho and of course Colorado itself.

The Colorado blue spruce is admired for its thick, fragrant blue foliage and their natural pyramidal shape. They are usually planted to function as a windbreak and birds love making their nests high up on the corse branches of this tree. It’s a great addition to any garden, especially the dwarf kind which is mostly planted to compliment shrubs and provide an attractive garden backdrop.

Planting Colorado blue spruce

Before you consider planting the beautiful Colorado blue spruce tree, you must find an ideal place to plant it in. Colorado blue spruce grows prolifically in moist soil so leave out the patch dry areas and look for well-watered soil. The Colorado blue spruce is generally considered a slow growing tree, but it grows even if planted in heavily polluted areas. However, it will reduce the growth rate even more and alter its natural blue foliage color.

After you have secured picked the right spot, you can now move onto the plantation part. There are quite a few ways you can propagate the Colorado blue spruce. The two most commonly used methods are planting seeds and planting cuttings.

  • Using Cutting:

Collect the cuttings from young branches. The next step is to dip the cutting in rooting hormone/auxin to stimulate the growth of roots from the cutting. You can then plant the cuttings into a container of peat and sand. You must be patient because it can take months before the roots develop well enough to plant it in the ground. However, make sure you place the container in a well-lit area.

  • Using seeds:

You can collect the seeds from the cones of mature Colorado blue spruce tree of your choice. The seeds are dropped from the cones during the spring season and when you plant them, you must expose them to about 15 hours of light every day. If the exposure of light falls below 12 hours, the seed will go dormant and you can bid your unborn tree farewell.

Caring and maintenance

The Colorado blue spruce trees are in optimum health when they’re planted in well-drained soil having a pH around 6.0 to 7.5. Never plant them in fully shaded areas and keep the soil aerated because waterlogged soil can be disastrous for them. A good way to help the soil retain its moisture is to add organic mulch around the tree, which also prevents the growth of pesky weeds.

You’re not the only Colorado blue spruce admirer in the garden, there might be pests lurking around that you ought to watch out for. Spider mites are one of the most common pests that leave webs on the foliage. These pests and many others can be avoided by applying petroleum-based plant oils to effectively reduce their population, allowing the tree to regain its full health. Do not use pesticides, not only are they harmful to the environment but they often end up increasing mite population.
