With striking foliage of a silvery blue-green color, it is no wonder the Juniperus chinensis ‘Blue Point’ is a popular shrub. This shrub or tree is more commonly known as the Blue Point Juniper.
The nickname, other than referencing its scientific one, was allocated due to the tree’s foliage.
Early in the 1970s, the Blue Point Juniper was found. This form of the tree was selected and chosen for its beautiful and uniquely colored foliage. The tree was also appreciated for its strong and upright habit.
Originally the Juniperus chinensis ‘Blue Point’ grew naturally in Mongolia, Japan, and China.
In its natural habitat on hillsides or in rocky places, the Blue Point Juniper would develop into a large tree. It could grow to staggering heights of around 18m (60ft).
Juniperus chinensis ‘Blue Point’ grown nowadays grow rather steadily.
With new growth of roughly 30cm to 38cm (12in to 15in) each year. The ultimate size of the tree will depend on its age. After about ten years the Blue Juniper is known to reach a height of between 3m to 3.7m (10ft to 12ft).
As a conifer, the Blue Point Juniper will continue to grow throughout its life. At a young age, these trees appear to be rather upright and narrow.
As they grow, however, they slowly broaden and take on a more substantial look. The width of the Juniperus chinensis ‘Blue Point’ will continue to stay relative to its height at about two-thirds.
Generally, a mature Blue Point Juniper will reach a spread of about 1.8m to 2.4m (6ft to 8ft). It grows its branches densely and forms a broad pyramid shape.
Juniperus chinensis ‘Blue Point’ Care
Blue Point Juniper trees are among the easier trees to care for and maintain. They are not bothered about extremely hot or cold temperatures. In fact, they are hardy in temperatures as low as -34°C (-30°F). And, although they would ideally be in a location that gives them access to full sun, they will adapt to being in partial shade. These trees will usually only require an annual session of pruning. However, left alone, they will grow in a naturally beautiful rugged way. Shaping and topiary are also possible to do with the Juniperus chinensis ‘Blue Point’.

Planting the Juniperus chinensis ‘Blue Point’
The first step in your task of planting your Juniperus chinensis ‘Blue Point’ is deciding what its purpose will be. Planting will vary slightly depending on whether you want your Blue Point Juniper as a landscaping feature or if you will be creating a border or privacy screen.
What does not change, however, is the manner in which you should plant this tree. The only variable that will be adjusted accordingly is the spacing you leave between your trees.
To begin, you will need to dig a hole that is twice the width of the root ball of your Blue Point Juniper. You should then place your tree into its hole. Next, the soil needs to be backfilled and stamped down to eliminate any air pockets. The last thing to do is water it!
Problems may begin to arise if the spacing of your Juniperus chinensis ‘Blue Point’ is not taken into consideration. You need to plan for the growth and spread of your tree.
Used to create a screen or windbreaker the spacing between each planting site should be between 1.8m and 2.4m (6ft and 8ft). This will eventually grow into a dense screen. If you would rather more of an avenue of trees, you should allow spacing of about 3m to 3.7m (10ft to 12ft).
You should also leave a distance of about 1.2m (4ft) between the Blue Point Juniper and any other type of plant. This is necessary even when you are using the tree in a group planting situation.
Propagation of the Juniperus Blue Point
To propagate the Juniperus chinensis ‘Blue Point’ you will need a cutting from a mature tree’s branch. Cuttings should be taken during the springtime. With proper care, by the following spring, the cutting should have developed some roots.
The size you should aim for when taking a cutting from your Blue Point Juniper is between 20cm and 25cm (8in and 10in). It is recommended that the branch you choose to take the cutting from is healthy.
It should also have a decent amount of needles growing from its tip. Remember to remove the bottom 5cm (2in) of needles around the cut side of the removed bit of branch.
To aid in and encourage root growth you should make slits through the outer laver of the branch. These slits should be about 2.5cm to 5cm (1in to 2in) in length. Making these slits on each side of the bared stem will allow the branch to absorb more water.
Pests and diseases
Juniperus chinensis ‘Blue Point’ is not a very problematic tree. They have a high resistance to animals such as deer. They are also not very appealing to pests. Although, it is also good to check your Blue Point Juniper for spider mite or bagworm infestations.

These diseases are harmful to your Blue Point Juniper and will not just affect its foliage. In severe cases, your tree may even die.
