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.

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.

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.
